1.4 Criticisms Of Fundamental Analysis
The biggest criticisms of fundamental analysis come primarily from two groups: proponents of technical analysis and believers of the efficient market hypothesis.
Technical Analyst
- Technical analysis is the other primary form of security analysis. Put simply, technical analysts base their investments (or, more precisely, their trades) solely on the price and volume movements of stocks. Using charts and other tools, they trade on momentum and ignore the fundamentals.
- One of the basic tenets of technical analysis is that the market discounts everything. All news about a company is already priced into the stock. Therefore, the stock's price movements give more insight than the underlying fundamentals of the business itself.
Efficient Market Hypothesis (EMH)
Followers of the efficient market hypothesis (EMH), however, are usually in disagreement with both fundamental and technical analysts. The efficient market hypothesis contends that it is essentially impossible to beat the market through either fundamental or technical analysis. Since the market efficiently prices all stocks on an ongoing basis, any opportunities for excess returns are almost immediately whittled away by the market's many participants, making it impossible for anyone to meaningfully outperform the market over the long term.
The weak form EMH stipulates that current asset prices reflect past price and volume information. The information contained in the past sequence of prices of a security is fully reflected in the current market price of that security. The weak form of the EMH implies that investors should not be able to outperform the market using something that "everybody else knows". Yet, many financial researchers study past stock price series and trading volume (using a technique called technical analysis) data in an attempt to generate profits.
The semi-strong form of the EMH states that all publicly available information is similarly already incorporated into asset prices. In other words, all publicly available information is fully reflected in a security's current market price. Public information here includes not only past prices but also data reported in a company's financial statements, its announcements, economic factors and others. It also implies that no one should be able to outperform the market using something that "everybody else knows". The semi-strong form of the EMH thus indicates that a company's financial statements are of no help in forecasting future price movements and securing high investment returns in the long-term.
The strong form of the EMH stipulates that private information or insider information too is quickly incorporated in market prices and therefore cannot be used to reap abnormal trading profits. Thus, all information, whether public or private, is fully reflected in a security's current market price. This means no long-term gains are possible, even for the management of a company, with access to insider information. They are not able to take the advantage to profit from information such as a takeover decision which may have been made a few minutes ago. The rationale to support this is that the market anticipates in an unbiased manner, future developments and therefore information has been incorporated and evaluated into market price in a much more objective and informative way than company insiders can take advantage of.
Know Important Steps In Fundamental Analysis
2.1 Macro Economic Analysis
The level of economic activity has an impact on investment in many ways. If the economy grows rapidly, the industry can also be expected to show rapid growth and vice versa. When the level of economic activity is low, stock prices are low, and when the level of economic activity is high, stock prices are high reflecting the prosperous outlook for sales and profits of the firms. The analysis of macro economic environment is essential to understand the behaviour of the stock prices.
Macro Economics Factors
The commonly analysed macro economic factors are as follows.
Gross Domestic Product (GDP) - GDP indicates the rate of growth of the economy. GDP represents the aggregate value of the goods and services produced in the economy. GDP consists of personal consumption expenditure, gross private domestic investment and government expenditure on goods and services and net export of goods and services. The estimates of GDP are available on an annual basis. The rate of growth of GDP is around 6% in the nineties. The GDP growth in 1998-99 has accelerated to 5.8 percent compared to 5 per cent of the previous year. The growth rate of economy points out the prospects for the industrial sector and the return investors can expect from investment in shares. The higher growth rate is more favourable to the stock market.
Savings And Investment - It is obvious that growth requires investment which in turn requires substantial amount of domestic savings. Stock market is a channel through which the savings of the investors are made available to the corporate bodies. Savings are distributed over various assets like equity shares, deposits, mutual fund units, real estate and bullion. The saving and investment patterns of the public affect the stock to a great extent.
Inflation - Along with the growth of GDP, if the inflation rate also increases, then the real rate of growth would be very little. The demand in the consumer product industry is significantly affected. The industries which come under the government price control policy may lose the market, for example Sugar. The government control over this industry, affects the price of the sugar and thereby the profitability of the industry itself. If thee is a mild level of inflation, it is good to the stock market but high rate of inflation is harmful to the stock market.
Interest Rates - The interest rate affects the cost of financing to the firms. A decrease in interest rate implies lower cost of finance for firms and more profitability. More money is available at a lower interest rate for the brokers who are doing business with borrowed money.
Budget - The budget draft provides an elaborate account of the government revenues and expenditures. A deficit budget may lead to high rate of inflation and adversely affect the cost of production. Surplus budget may result in deflation. Hence, balanced budget is highly favourable to the stock market.
The Tax Structure - Every year in March, the business community eagerly awaits the Government's announcement regarding the tax policy. Concessions and incentives given to a certain industry encourages investment in that particular industry. Tax reliefs given to savings encourage savings. The minimum Alternative Tax (MAT) levied by the Finance Minister in 1996 adversely affected the stock market. Ten type of tax exemption has impact on the profitability of the industries.
The Balance Of Payment - The balance of payment is the record of a country's money receipts from and payments abroad. The difference bt6ween receipts and payments may be surplus or deficit. Balance of payment is a measure of the strength of rupee on external account. If the deficit increases, the rupee may depreciate against other currencies, thereby, affecting the cost of imports. The industries involved in the export and import are considerably affected by the changes in foreign exchange rate. The volatility of the foreign exchange rate affects the investment of the foreign institutional investors in the Indian stock market. A favourable balance of payment renders a positive effect on the stock market.
Monsoon And Agriculture - Agriculture is directly and indirectly linked with the industries. For example, Sugar, Cotton, Textile and Food processing industries depend upon agriculture for raw-material. Fertilizer and insecticide industries are supplying inputs to the agriculture. A good monsoon leads to higher demand for input and results in bumper crop. This would lead to buoyancy in the stock market. When the monsoon is bad, agricultural and hydel power production would suffer. They cast a shadow on the share market.
Infrastructure Facilities - Infrastructure facilities are essential for the growth of industrial and agricultural sector. A wide net work of communication system is a must for the growth of the economy. Regular supply of power without any power cut would boost the production. Banking and financial sectors also should be sound enough to provide adequate support to the industry and agriculture. Good infrastructure facilities affect the stock market favorably. In India even though infrastructure facilities have been developed, still they are not adequate. The government has liberalized its policy regarding the communication, transport and power sector. For example, power sector has been opened up to the foreign investors with assured rates of returns.
Demographic Factors - The demographic data provides details about the population by age, occupation, literacy and geographic location. This is needed to forecast the demand for the consumer goods. The population by age indicates the availability of able work force.
2.2 Economic Analysis
To estimate the stock price changes, an analyst has to analyse the macro economic environment and the factors peculiar to the industry he is concerned with. The economic activities affect the corporate profits, investors, attitude and the share prices. Fall in the GDP or a slackness inn the economic growth may lead to fall in corporate profit and consequently the security prices. For the purpose of economic analysis, an analyst should be familiar with the forecasting techniques. He should know the advantages and disadvantages of various techniques. The common techniques used are analysis of key economic indicators, diffusion index, surveys and econometric model building. These techniques help him to decide the right time to invest and the type of security he has to purchase i.e. stocks or bonds or some combination of stocks and bonds.
Key Economic Indicators
The economic indicators are factors that indicators are factors that i8ndicate the present status, progress or slow down of the economy. They are capital investment, business profits, money supply, GNP, interest rate, unemployment rate, etc. The economic indicators are grouped into leading, coincidental and lagging indicators. The indicators are selected on the following criteria.
Economic significance
Statistical adequacy
Timing
Conformity
Diffusion Index
Diffusion index is a composite or consensus index. The diffusion index consists of leading, coincidental and lagging indicators. This type of index has been constructed by the National Bureau of economic Research in USA. But the diffusion index is complex in nature to calculate and the irregular movements that occur in individual indicators cannot be completely eliminated.
Econometric Model Building
For model building several economic variables are taken into consideration. The assumptions underlying the analysis are specified. The relationship between the independent and dependent variables is given mathematically. While using the model, the analyst has to think clearly all the inter-relationships are specified, he can forecast not only the direction but also the magnitude. But his prediction depends on his understanding of economic theory and the assumption on which the model has been built. The models mostly use simultaneous equations.
2.3 Industry Analysis
An industry is a group of firms that have similar technological structure of production and produce similar products. For the convenience of the investors, the broad classification of the industry is given in financial dailies and magazines. Companies are distinctly classified to give a clear picture about their manufacturing process and products. The table below gives the industry wise classification given in Reserve Bank of INDIA Bulletin.
- Food products
- Beverages, Tobacco and Tobacco products
- Textiles
- Wood and wood products
- Leather and leather products
- Rubber and plastic products
- Chemical and chemical products
- Non-metallic mineral products
- Basic metals, Alloys and metal products
- Machinery and Machine tools
- Transport equipment and parts
- Other Miscellaneous manufacturing industries
Classification
These industries can be classified on the basis of the business cycle i.e. classified according to their reactions to the different phases of the business cycle. They are classified into growth, cyclical, defensive and cyclical growth industry.
Growth Industry - The growth industries have special features of high rate of earnings and growth in expansion, independent of the business cycle.
Cyclical Industry - The growth and the profitability of the industry move along with the business cycle. During the boom period they enjoy growth and during depression they suffer a set back. For example, the white goods like fridge, washing machine and kitchen range products command a good market in the boom period and the demand for them slackens during the recession.
Defensive Industry - Defensive industry defies the movement of the business cycle. Ford example, food and shelter are the basic requirements of humanity. The food industry withstands recession and depression.
Cyclical Growth Industry - This is a new type of industry that is cyclical and at the same time growing. For example, the automobile industry experiences periods of stagnation, decline but they grow tremendously. The changes in technology and introduction of new models help the automobile industry to resume their growth path.
Life Cycle
In each of these industry- it is also important to understand what is the industry life cycle. The industry life cycle theory is generally attributed to Julius Grodensky. The life cycle of the industry is separated into four well defined stages such as
Pioneering stage - The prospective demand for the product is promising in this stage and the technology of the product is low. The demand for the product attracts many producers to produce the particular product.
Rapid growth stage - This stage starts with the appearance of surviving firms from the pioneering stage. The companies that have withstood the competition grow strongly in market share and financial performance.
Maturity and stabilization stage - In the stabilization stage, the growth rate tends to moderate and the rate of growth would be more or less equal to the industrial growth rate or the gross domestic product growth rate.
Declining stage - In this stage, demand for the particular product and the earnings of the companies in the industry decline. Now-a-days very few consumers demand black and white T.V. Innovation of new products and changes in consumer preferences lead to this stage. The specific feature of the declining stage is that even in the boom period, the growth of the industry would even in the boom period. Investment in the shares of these types of companies leads to erosion of capital.
Factors To Be Considered
Apart from industry life cycle analysis, the investor has to analyse some other factors too. They are as listed below
Growth of the industry - The historical performance of the industry in terms of growth and profitability should be analysed. Industry wise growth is published periodically by the Centre for Monitoring Indian Economy.
Cost structure and profitability - The cost structure, that is the fixed and variable cost, affects the cost of production and profitability of the firm.
Nature of the product - The products produced by the industries are demanded by the consumers and other industries.
Nature of the competition - Nature of competition is an essential factor that determines the demand for the particular product, its profitability and the price of the concerned company scrips.
Government policy - The government policies affect the very nerve of the industry and the effects differ from industry to industry. Tax subsidies and tax holidays are provided for export oriented products. Government regulates the size of the production and the pricing of certain products. The sugar, fertilizer and pharmaceutical industry are often affected by the inconsistent government policies. Control and decontrol of sugar price affect the profitability of the sugar industry. In some cases entry barriers are placed by the government. In the airways, private corporates are permitted to operate the domestic flights only. When selecting an industry, the government policy regarding the particular industry should be carefully evaluated. Liberalisation and delicensing have brought immense threat to the existing domestic industries in several sectors.
Labour - The analysis of labour scenario in a particular industry is of great importance. The number of trade unions and their operating mode have impact on the labour productivity and modernization of the industry. Textile industry is known for its militant trade unions. If the trade unions are strong and strikes occur frequently, it would lead to fall in the production.
Research and Development - For any industry to survive the competition in the national and international markets, product and production process have to be technically competitive. This depends on the R$D in the particular company or industry.
Pollution Standards - Pollution standards are very high and strict in the industrial sector. For some industries it may be heavier than others; for example, in leather, chemical and pharmaceutical industries the industrial effluents are more.
SWOT Analysis
The above mentioned factors themselves would become strength, weakness, opportunity and threat (SWOT) for the industry. Hence, the investor should carry out a SWOT analysis for the chosen industry. Take for instance, increase in demand for the industry's product becomes its strength, presence of numerous players in the market, i.e. competition becomes the threat to a particular company in the respective industry. The progress in the research and development in that particular industry is an opportunity and entry of multinationals in the industry and cheap imports of the particular products are threat to that industry. In this way the factors have to be arranged and analysed. To make the industry analysis more explanatory it has been carried out on the pharmaceutical industry and SWOT analysis results are also given.
2.4 Company Analysis
In the company analysis the investor assimilates the several bits of information related to the company and evaluates the present and future values of the stock. The risk and return associated with the purchase of the stock is analysed to take better investment decisions. The valuation process depends upon the investors ability to elicit information from the relationship and inter-relationship among the company related variables.
Points to Analyze in a Company
The Competitive Edge Of The Company - Major industries in India are composed of hundreds of individual companies. In the information technology industry even though the number of companies is large, few companies like Tata Infotech, Satyam computers, Infosys, NIIT etc. , control the major market share. The competitiveness of the company can be studied with the help of:
The market share - The market share of the annual sale helps to determine a company's relative competitive position within the industry. If the market share is high, the company would be able to meet the competition successfully.
Growth Of Sales - The Company may be a leading company, but if the growth in sales is comparatively lower than another company, it indicates the possibility of the company losing the leadership. The rapid growth in sales would keep the shareholder in a better position than one with the stagnant growth rate.
Stability Of Sales - If a firm has stable sales revenue, other things being remaining constant, will have more stable earnings. Wide variation in sales leads to variations in capacity utilization, financial planning and dividend.
Earnings Of The Company - Sales alone do not increase the earnings but the costs and expenses of the company also influence the earnings of the company. Further, earnings do not always increase with the increase in sales. The company's sales might have increased buy its earnings per share may decline due to the rise in costs. The rate of change in earnings differs from the rate of change of sales. Sales may increase by 10% in a company but earnings per share may increase only by 5%. Even though there is a relationship between sales and earnings, it is not a perfect one. Sometimes, the volume of sales may decline but the earnings may improve due to the rise in the unit price of the article. Hence, the investor should not depend only on he sales, but should analyse the earnings of the company.
Management - Good and capable management generates profit to the investors. The management of the firm should efficiently plan, organize, actuate and control the activities of the company. The basic objective of management is to attain the stated objectives of company for the good of the equity holders, the public and the employees. If the objectives of the company are achieved, investors will have a profit. A management that ignores profit does more harm to the investors than one that over emphasises it.
2.5 Financial Analysis
The best source of financial information about a company is its own financial statements. This is primary source of information for e valuating the investment prospects in the particular company's stock. Financial statement analysis is the study of a company's financial statement from various viewpoints. The statement gives the historical and current information about the company's operations. Historical financial statement helps to predict the future. The two main statements used in the analysis are:
The Balance Sheet
The balance sheet shows all the company's sources of fund (liabilities and stockholder's equity) and uses of funds at a given point of time. The balance sheet can either be in the horizontal form or vertical form.
The Profit And Loss Account
Analysis of the financial condition of the company requires a report on the flow of funds too. The income statement reports the flow of funds from business operations that take place in between two points of time. It lists down the items of income and expenditure. The difference between the income and expenditure represents profit or loss for the period. It is also called income and expenditure statement.
Analysis Of Financial Statements
The analysis of financial statements reveals the nature of relationship between income and expenditure, and the sources and application of funds. The investor determines the financial position and the progress of the company through analysis. The investor is interested in the yield and safety of his capital. He cares much about the profitability and the management's policy regarding the dividend. Towards this end, he can use the following simple analysis:
Comparative Financial Statement - In the comparative statement balance sheet figures are provided for ore than one year. The comparative financial statement provides time perspective to the balance sheet figures. The annual date are compared with similar data of previous years, either in absolute terms or in percentages.
Trend Analysis - Here percentages are calculated with a base year. This would provide insight into the growth or decline of the sale or profit over the years. Sometimes sales may be increasing continuously, and the inventories may also be rising. This would indicate the loss of market share of the particular company's product. Likewise sales may have an increasing trend but profits may remain the same. Here the investor has to look in the cost and management efficiency of the company.
Comon Size Statement - Common size balance sheet shows the percentage of each asset item to the total assets and each liability item to the total liabilities. Similarly, a common size income statement shows each item of expense as a percentage of net sales. With common size statement comparison can be made between two different size firms belonging to the same industry. For a same company over the years common size statement can be prepared.
Fund Flow Analysis - The balance sheet gives a static picture of the company's position on a particular date. It does not reveal the changes that have occurred in the financial position of the unit over a period of time. The investor should know,
How are the profits utilized?
Financial source of dividend
Source of finance for capital expenditures
Source of finance for repayment of debt
The destiny of the sale proceeds of the fixed assets and
Use of the proceeds of the proceeds of the share or debenture issue or fixed deposits raised from public.
These items of information are provided in the funds flow statement. It is a statement of the sources and applications of funds. It highlights the changes in the financial condition of a business enterprise between two balance sheet dates. The investor could see clearly the amount of funds generated or lost in operations. He could see how these funds have been divided into three significant uses like taxes, dividends and reserves. Moreover, the application of long the funds towards the acquisition of current assets can be found out. This would reveal the real picture of the financial position of the company.
Cash Flow Statement - The investor is interested in knowing the cash inflow and outflow of the enterprise. The cash flow statement is prepared with the help of balance sheet, income statement and some additional information. It can be either prepared in the vertical form or in the horizontal form. Cash flows related to operations and other transactions are calculated. The statement shows the causes of changes in cash balance between two balance sheet dates. With the help of this statement the investor can review the cash movements over an operating cycle. The factors responsible for the reduction of cash balance in spite of increase in profits or vice versa can be found out
Ratio Analysis - Ratio is a relationship between two figures expressed mathematically. Financial ratio provides numerical relationship between two relevant financial data. Financial ratios are calculated from the balance sheet and profit and loss account. The relationship can be either expressed as a percent pr as a quotient. Ratios summaries the data for easy understanding, comparison and interpretation.
2.6 Valuation
- Valuation analysis is conducted to decide whether the stock of a company is currently selling at attractive (cheap/undervalued), fair (rightly priced) or expensive (overvalued) valuations. It is done post-financial analysis, to select stocks for further analysis.
- Once an investor has found a financially strong company by using the parameters highlighted in the financial analysis guide, she should do the valuation analysis to check whether the stock of the company is priced right.
- If the shares of a company are overvalued then the investor should avoid investing in it, however good the company's financial position may be. Investing hard-earned money in overvalued stocks exposes the investor to higher levels of risk where the potential of future appreciation is limited but the risk of loss of money is high. Therefore, valuation analysis becomes paramount before taking a decision to buy any stock.
- Valuation analysis compares the stock market values of the stock of a company with its financial parameters. Stock market values consist of the current market price (CMP), market capitalization (MCap) etc. Various financial parameters, which are used in valuation analysis, are earning per share (EPS), sales, sales growth rate, earnings (EPS) growth rate, book value, shareholder's equity, dividend payout etc
Understanding Basic Terms In Fundamental Analysis
3.1 Time Value Of Money
If we have to evaluate, what would be the value of money that we have today sometime in the future, then we need to move the 'money today' through the future. This is called the "Future Value (FV)" of the money. Likewise, if we have to evaluate the value of money that we are expected to receive in the future in today's terms, then we have to move the future money back to today's terms. This is called the "Present Value (PV)" of money. In both the cases, as there is a passage of time, the money has to be adjusted for the opportunity cost. This adjustment is called "Compounding" when we have to calculate the future value of money. It is called "Discounting" when we have to calculate the present value of money.
The present value of an asset could be shown to be:
PV= FV/(1+r)^t
The Future Value of an asset is calculated as:
FV= PV*(1=r)^t
Where,
PV = Present Value
FV = Future Value
r = Discount Rate
t = Time
Example 1: How much is Rs.10000/- in today's terms worth five years later assuming an opportunity cost of 10%?
This is a case of Future Value (FV) computation, as we are trying to evaluate the future value of the money that we have today -
Future Value = Present Value * (1+ opportunity cost rate) ^ Number of years.
= 10000 *(1 + 1.10%) ^ 5 = 16105.
This means Rs.10000 today is comparable with Rs.16105 after 5 years, assuming an opportunity cost of 10%
Example 2: How much is Rs.10,000/- receivable after 6 years, worth in today's terms assuming an opportunity cost of 10%?
This is clearly the case of Present Value (PV) computation as we are trying to evaluate the present value of cash receivable in future in terms of today's value.
Present Value = Amount / (1+Discount Rate) ^ Number of years
= 10,000 / (1+ 10% ) ^ 6 = 5644
This means Rs.10,000/- receivable after 6 years in future is comparable to Rs.5644 in today's terms assuming a discount rate of 10%
Thus, the time value of money is like your money getting older. There are things you can do in your 20s that hurt when you are in your 40s. Just try hiking that mountain. Even though the mountain hasn't changed, it requires a different amount of effort, pain, and dedication to get to the top. The same hundred-rupee note in 20 years from now is a lot weaker than that hundred-rupee note in your pocket today - due both to inflation and the interest you could earn on it in the meantime.
3.2 Net Present Value Of The Asset
Net Present Value (NPV) is the value of all future cash flows (positive and negative) over the entire life of an investment discounted to the present.
Basically it refers to the rupee value derived by deducting the present value of all the cash outflows of the company from the present value of the total cash inflows. It is widely used in finance and to know the profitability of the project.
- If the Net present value is positive, then the project should be accepted. It indicates that earning from the project is more than the amount invested in the project, so the project should be accepted.
- If the Net present value is negative, then it indicates that the project in which we invested the money does not provide a positive return, so the project should be rejected.
Mathematically, NPV Formula is represented as,
NPV = Cash Flows /(1- i)t - Initial Investment
Where,
- i stands for the Required Rate of Return or Discount Rate
- t stands for Time or Number of Period
Example-
Lets say a friend of your needs Rs.500 now, and will pay you back Rs.570 in a year. Is that a good investment when you can get 10% elsewhere?
Money Out: Rs.500 now
You invested Rs.500 now, so PV = -500.00
Money In: Rs.570 next year
PV = 570 / (1+0.10)1= 570 / 1.10 = Rs.518.18
The Net Amount is:
Net Present Value = 518.18 - 500.00 = 18.18
So, at 10% interest, that investment is worth 18.18
A Net Present Value (NPV) that is positive is good (and negative is bad).
But your choice of interest rate can change things!
Example: Same investment, but try it at 15%
Money Out: 500
You invested 500 now, so PV = -500.00
Money In: 570 next year:
PV = 570 / (1+0.15)1 = 570 / 1.15 = 495.65
Work out the Net Amount:
Net Present Value = 495.65 - 500.00 = -4.35
So, at 15% interest, that investment is worth - Rs.4.35
It is a bad investment. But only because you are demanding it earn 15% (maybe you can get 15% somewhere else at similar risk).
Let us try a bigger example.
Example: Invest Rs.2,000 now, receive 3 yearly payments of Rs.100 each, plus Rs.2,500 in the 3rd year. Use 10% Interest Rate.
Let us work year by year (remembering to subtract what you pay out):
- Now: PV = -2,000
- Year 1: PV = 100 / 1.10 = 90.91
- Year 2: PV = 100 / 1.102= 82.64
- Year 3: PV = 100 / 1.103= 75.13
- Year 3 (final payment): PV = 2,500 / 1.103= 1,878.29
Adding those up gets: NPV = -2,000 + 90.91 + 82.64 + 75.13 + 1,878.29 = 126.97
Looks like a good investment.
Why is the NPV higher when the interest rate is lower?
- Because the interest rate is like the team you are playing against, play an easy team (like a 6% interest rate) and you look good, a tougher team (like a 10% interest) and you don't look so good!
- You can actually use the interest rate as a "test" or "hurdle" for your investments: demand that an investment have a positive NPV with, say, 6% interest.
3.3 Opportunity And Discount Factors
Opportunity Cost
Opportunity cost is the cost of any activity measured in terms of the value of the other alternative that is not chosen (that is foregone). Put another way, it is the benefit you could have received by taking an alternative action; the difference in return between a chosen investment and one that is not taken. Say you invest in a stock and it returns 10% over a year. In placing your money in the stock, you gave up the opportunity of another investment - say, a fixed deposit yielding 8%. In this situation, your opportunity costs are 2% (10% - 8%). But do you expect only fixed deposit returns from stocks? Certainly not. You expect to earn more than the return from fixed deposit when you invest in stocks. Otherwise you are better off with fixed deposits. The reason you expect higher returns from stocks is because the stocks are much riskier as compared to fixed deposits. This extra risk that you assume when you invest in stocks calls for additional return that you assume over other risk-free (or near risk-free) return.
The discount rate of cost of capital to be used in case of discounting future cash flows to come up with their present value is termed as Weighted Average Cost of Capital (WACC).
Where
D = Debt portion of the Total Capital Employed by the firm
TC = Total Capital Employed by the frim (D+E+P)
Kd = Cost of Debt of the Company.
t = Effective tax rate of the firm
E = Equity portion of the Total Capital employed by the firm
P = Preferred Equity portion of the Total Capital employed by the firm
Kp = Cost of Preferred Equity of the firm
The Cost of equity of the firm, Ke (or any other risky asset) is given by the Capital Asset
Pricing Model (CAPM)
or,
Where
Rf = Risk-free rate
β = Beta, the factor signifying risk of the firm
Rm = Implied required rate of return for the market
Risk-Free Rate
The risk-free interest rate is the theoretical rate of return of an investment with zero risk, including default risk. Default risk is the risk that an individual or company would be unable to pay its debt obligations. The risk-free rate represents the interest an investor would expect from an absolutely risk-free investment over a given period of time.
Though a truly risk-free asset exists only in theory, in practice most professionals and academics use short-dated government bonds of the currency in question. The risk-free interest rate for the Indian Rupee for Indian investors would be the yield on Indian government bonds denominated in Indian Rupee of appropriate maturity.
These securities are considered to be risk-free because the likelihood of governments defaulting is extremely low and because the short maturity of the bills protect investors from interest-rate risk that is present in all fixed rate bonds .
Though Indian government bond is a risk less security per se, a foreign investor may look at the India's sovereign risk which would represent some risk. As India's sovereign rating is not the highest a foreign investor may consider investing in Indian government bonds as not a risk free investment.
Equity Risk Premium
The notion that risk matters and that riskier investments should have higher expected returns than safer investments, to be considered good investments, is both central to modern finance.
Thus, the expected return on any investment can be written as the sum of the risk-free rate and a risk premium to compensate for the risk. The equity risk premium reflects fundamental judgments we make about how much risk we see in an economy/market and what price we attach to that risk.
In effect, the equity risk premium is the premium that investors demand for the average risk investment and by extension, the discount that they apply to expected cash flows with average risk.
When equity risk premia rises, investors are charging a higher price for risk and will therefore pay lower prices for the same set of risky expected cash flows. Equity risk premia are a central component of every risk and return model in finance and is a key input into estimating costs of equity and capital in both corporate finance and valuation.
The Beta
The Beta is a measure of the systematic risk of a security that cannot be avoided through diversification. Therefore, Beta measures non-diversifiable risk. It is a relative measure of risk: the risk of an individual stock relative to the market portfolio of all stocks. Beta is a statistical measurement indicating the volatility of a stock’s price relative to the price movement of the overall market. Higher-beta stocks mean greater volatility and are therefore considered to be riskier but are in turn supposed to provide a potential for higher returns; low-beta stocks pose less risk but also lower returns
Thus, it is a measure of the volatility-or systematic risk-of a security or portfolio compared to the market as a whole. Beta data about an individual stock can only provide an investor with an approximation of how much risk the stock will add to a (presumably) diversified portfolio. For beta to be meaningful, the stock should be related to the benchmark that is used in the calculation.

= Coefficient of Correlation between security and market returns
How Beta Works ?
A beta coefficient can measure the volatility of an individual stock compared to the systematic risk of the entire market. In statistical terms, beta represents the slope of the line through a regression of data points. In finance, each of these data points represents an individual stock's returns against those of the market as a whole. Beta effectively describes the activity of a security's returns as it responds to swings in the market. A security's beta is calculated by dividing the product of the covariance of the security's returns and the market's returns by the variance of the market's returns over a specified period.
Types Of Beta Values
- Beta Value Equal To 1.0
- If a stock has a beta of 1.0, it indicates that its price activity is strongly correlated with the market. A stock with a beta of 1.0 has systematic risk. However, the beta calculation can't detect any unsystematic risk. Adding a stock to a portfolio with a beta of 1.0 doesn't add any risk to the portfolio, but it also doesn't increase the likelihood that the portfolio will provide an excess return.
- Beta Value Less Than One
- A beta value that is less than 1.0 means that the security is theoretically less volatile than the market. Including this stock in a portfolio makes it less risky than the same portfolio without the stock. For example, utility stocks often have low betas because they tend to move more slowly than market averages.
- Beta Value Greater Than One
- A beta that is greater than 1.0 indicates that the security's price is theoretically more volatile than the market. For example, if a stock's beta is 1.2, it is assumed to be 20% more volatile than the market. Technology stocks and small cap stocks tend to have higher betas than the market benchmark. This indicates that adding the stock to a portfolio will increase the portfolio's risk, but may also increase its expected return.
- Negative Beta Value
- Some stocks have negative betas. A beta of -1.0 means that the stock is inversely correlated to the market benchmark. This stock could be thought of as an opposite, mirror image of the benchmark's trends. Put options and inverse ETFs are designed to have negative betas. There are also a few industry groups, like gold miners, where a negative beta is also common.
Problems With Beta
- The Beta is just a tool and as is the case with any tool, is not infallible. While it may seem to be a good measure of risk, there are some problems with relying on beta scores alone for determining the risk of an investment. Beta is not a sure thing. For example, the view that a stock with a beta of less than 1 will do better than the market during down periods may not always be true in reality. Beta scores merely suggest how a stock, based on its historical price movements will behave relative to the market.
- Beta looks backward and history is not always an accurate predictor of the future. Beta also doesn't account for changes that are in the works, such as new lines of business or industry shifts. Indeed, a stock's beta may change over time though usually this happens gradually.
