Beginning from 1991, India¶s financial system took a radically new turn
towards the market model. This envisaged an increased rol e for the
capital market, along with a fundamental restructuring of banks and
financial institutions. Such restructuring has been rather slow. The bulk
of the banking system and major financial institutions are still largely
owned and controlled by the government.
1.1 Financial Firms in India
The corporate sector desiring long-term funds can raise it by issuing
shares and debentures to the members of the public. The corporate sector
can also approach financial institutions for satisfying their long term
financial needs. The financial institutions are concerned with mobilizing
resources from different sections of society for their channelisation in
productive way. The financial institutions provide a convenient and
effective li nk betw een savings and investment. T hey pool the savings of
the society and are used by them to cater to the needs of the corporate
sector.
In India, we have a battery of financial institutions operating in
capital market and rendering financial assistance to needy enterprises.
These financial institutions can be categorised into three major groups.
1. Commercial Banks.
2. Development Banks.
3. Investing Institutions
1.1.1 Commercial Banks

The Commercial Banks are the oldest institutions having a wide network
of branches commanding utmost public confidence and having the lion¶s
share in the total banking operations. The Commercial Banks operating
in India fall under a number of sub-categories on the basis of ownership
and control of management. They constitute a vital role Indian financial
system. These financial institutions have been major suppliers of
working capital finance to the corporate sector.
The Commercial Banks assist enterprises by granting term loans
and various kinds of financial modes. They render help to the corporate
sector in raising long term funds from capital market through merchant
banking activity. Let us discuss the nature of long term financing of
business by t he commercial banks.
1. Term Lending.
2. Underwriting.
3. Direct subscription.
4. Merchant banking activity.
1.1.2 Development Banks
The Development Banks are also known as Industrial Banks. The
development banks supply capital, knowledge and enterprise. They meet
the requirements of industries. They provide long term investments.
They are able to finance the long term investments. They employ
financial experts to render the services to the prospecting projects. These
banks acquire funds by issuing their own shares and debentures and
obtain loans from the Central government and international agencies.
They are performing important functions for rapid industrialisation of
the country. They inquire and investigate the prospects of the industry

and feasibility and utilities of the various schemes. They advise the
industries in financial and non financial matters of the corporate secto r.
The functions of industrial banks can be categorised into three parts:
a) Accepting of long term deposits.
b) Permitting of long term investments.
c) Consultancy services.
The deposits are mobilised by these banks by giving higher rate of
interest to the depositors. These banks grant direct financial aids to the
industries. Long term loans are sanctioned usually on the mortgage or
land, machine and other fixed assets. The companies require short term
funds for purchase of raw materials and other payments. The short term
credit is provided by Commercial Banks. The important industrial banks
in India are:
1) IDBI
2) ICICI
3) IFCI
1.2 Objective
1. The purpose of doing study is to understand the security pricing
theories viz, CAPM & SML by application.
2. To find the pricing status of securities of financial firms.
3. Test of asset pricing theories such as CAPM and Test of Market
Efficiency.
4. To know the return and risk of the stocks.

1.3 Scope
1. The study is based on the securities listed on National Stock
Exchange (NSE) of India Ltd.
2. The Study¶s scope is confined to securities of financial services
firms in India from 1 s t Jan 2007 to 31 s t Dec 2008, They are :
a) Industrial Development Bank of India Ltd.
b) India Bulls.
c) Bajaj Auto Finance Ltd.
d) Housing Development Finance Corporation Ltd.
e) LIC Housing Finance.
1.4 Methodology
Research Design
Research is conducted on the equity shares listed in the National
Stock Exchange (NSE). Research consists of analyzing the equity shares
and Calculation of return and betas of stocks.
Data Collection Methods & Techniques:
The collection of data is through Secondary Research
Secondary Research
1. Internal Secondary Data: The data generated within the
organization such as financial reports, share prices at different
time period.
8/8/2019 Security Market Line With Reference to Financial Firms in India
http://slidepdf.com/reader/full/security-market-line-with-reference-to-financial-firms-in-india 8/88

2. External Secondary Data: The data generated by sources outside
the organization such as government reports, data collected by
syndicate, etc.
1.5 Limitations of the Study
1. Inadequacies or Incorrectness of Data: An analyst has to wrestle
with inadequate or incorrect data. While deliberat e falsif ication of
data may be rare, subtle misrepresentation and concealment are
common. Often, an experienced and skilled analyst may be able to
detect such ploys and cope with them. However, in some instances,
he too is likely to be misled by them into drawing wrong
conclusions.
2. Future Uncertainties: Future changes are largely unpredictable,
more so when the economic and business environment is buffeted
by frequent winds of change. In an environment characterized by
discontinuities, the past record is poor guide to future
performance.
3. Irrational Market Behaviour: The market itself presents a major
obstacle to the analyst. On account of neglect of prejudice,
undervaluation may persist for extended periods, likewise
overvaluations arising from unjustified optimism and misplaced
enthusiasm may endure for unreasonable lengths of time. The slow
correction of under or overvaluation poses a threat to the analyst.
Before the market eventually reflects the values established by the
analyst, new forces may emerge.

This chapter consists of Literature review by various authors and
introduction to concepts and terms like Capital Asset Pricing Model,
Security Market Line and various terms used in these concepts like
Retun, Risk, Risk free rate to name a few.
2.1 Capital Asset Pricing Model (CAPM)
Capital Asset Pricing Model was developed in 1960¶s. the model
has been attributed to William sharp, John Linter and Jan Mossin
independently. Consequently, t he model is often referred to as Sharpe -
Lintner-Mossin capital Asset Pricing Model.
The capital asset pricing model or CAPM is really an extension of
the portfolio theory of Markowitz. The portfolio theory is a description
of how rational investors should build efficient portfolios and select the
optimal portfolio. The capital markets if everyone behaved in the way
the portfolio theory suggested.
The relationship between risk and return established by the
security market line is known as the capital asset pricing model. It is
basically a simple linear relat ionship and ther efore, larger would be the
return expected by the investors. In other words, all securities are
expected to yield returns commensurate with their riskiness as measured
by Beta.
CAPM represents one of the most important discoveries in the
field of finance. It describes the expected return for all assets and
portfolios of assets in the economy. The difference in the expected
returns of any two assets can be related to the difference in their betas.
The model postulat es that systematic risk is the only import ant
8/8/2019 Security Market Line With Reference to Financial Firms in India
http://slidepdf.com/reader/full/security-market-line-with-reference-to-financial-firms-in-india 10/88
10
ingredient in determining expected return. As investors can eliminate all
unsystematic risk through diversification, they can be expected to be
rewarded only for bearing systematic risk. Thus, the relevant risk of an
asset is its systematic risk and not the total risk.
Assumptions of CAPM:
1. Investors make their investment decisions on the basis of risk
return assessments measured in terms of expected returns and
standard deviation of returns.
2. The purchase or sale of a security can be undertaken in infinitely
divisible units.
3. Purchases and sales by a single investor cannot affect prices. This
means that there is perfect competition where investors in total
determine prices by their actions.
4. There are no transaction costs. Given the fact that transaction
costs are small, they are probably of minor importance in
investment decision-making, and hence they are ignored.
5. There are no personal income taxes. Alternatively, the tax rates on
dividend income and capital gains are the same, there by making
the investor indifferent to the form in which the return on the
investment is received.
6. The investor can lend or borrow any amount of funds desired at a
rate of interest equal to the rate for risk less securities.
7. The investor can sell short any amount of any share.

11
The above assumptions are untenable. However, they do not
materially alter the real world. Moreover, the model describes the risk
return relationship and the pricing of assets fairly well.
2.2 Security Market Line
One of the contributions of modern portfolio theory to the field of
investments is the concept of modern portfolio theory to field of investments is the
concept of security market line (SML)
The SML simply represents the average or normal trade off between risk and
return for a group of security where risk is measured typically in terms of the security
betas.
For calculation of SML average historical rates of return for security are plotted
against their betas for a particular time period. Then a straight line is fitted to the plots
by regression and this is called the SML
Security Market L ine (SML) Graph
8/8/2019 Security Market Line With Reference to Financial Firms in India

12
The securities which plot above the expose SML generated above
normal returns for their risk as measured by their beta for the particular
time period used in constructing the SML.
Those securities which plot below the SML generated below normal
rate for the systematic risk.
Applicati on of SML:
1. Evaluating the performance of portfolio manager.
2. Test of asset pricing theories such as CAPM.
3. Test of market efficiency.
2.3 Return
2.3.1 Historical return:
The proper measurement of return generated by an investment
must account for both the price change and the cash flow derived during
the period the assets was held i.e. the return from the investment
includes both current income and capital gain or los ses due to
appreciation or deprecation in the price of the security then the income
and capital gain are expressed as a percentage of the total annual income
and capital gain as percentage of investment.
Any investor always expects a good rate of return from his
investment. Rate of Return is defined as the total income the investor
receives during the holding period of he assets, the returns is calculated
by using the for mula:
Today¶s Return = Today¶s price ± Yesterd ays price
Yesterday¶s price
* 100

http://slidepdf.com/reader/full/security-market-line-with-reference-to-financial-firms-in-india 13/88
13
Rate or return can be stated semi annually or annually or to
compare different investment alternative available. If the investment
alternative is a stock the investor gets a dividend and the capital
appreciation as return, if it is a debt instrument investor gets the interest
and capital appreciation, If the debt instrume nt is redeemed above the
face value.
2.4 Risk
In the context of security analysis risk is interpreted essentially in
terms of the variability of security returns and the most common measure
of risk of a security is the varia nce and standard deviation of return.
The square of standard deviation is called variance hence variance
of security returns is the average value of the square of deviations of the
observed returns from the expected value of return.
2.4.1 Systematic Risk:
In finance, systematic risk, also someti mes called market
risk, aggregate risk, or undiversifiable risk, is the risk associated with
aggregate market returns. Systematic risk is a risk of security that cannot
be reduced through diversification
In the capital asset pri cing model, th e rate of return requir ed for
an asset in market equilibrium depends on the systematic risk associated
with returns on the asset, that is, on the covariance of the returns on the
Today¶s Market Return = Today¶s index± Yesterd ays index
Yesterday¶s index
* 100
Total Risk = systematic risk + unsystematic risk
8/8/2019 Security Market Line With Reference to Financial Firms in India
http://slidepdf.com/reader/full/security-market-line-with-reference-to-financial-firms-in-india 14/88
14
asset and the aggregate returns to the market. Risk in asset returns that is
uncorrelated with aggregate market returns is called 'specific risk',
'diversifiable risk', or 'idiosyncratic risk'. Given diversified holdings of
assets, each individual investors exposure to idiosyncratic risk
associated with any particular asset is smal l and uncorrelated with the
rest of their portfolio. Hence, the contribution of idiosyncratic risk to the
riskiness of the portfolio as a whole is negligible. It follows that only
systematic risk needs to be taken into account.
2.4.2 Risk-free Assets:
Though a truly risk-free asset exists only in theory, in practice
most professi onals and academics use short -dated government bonds of
the currency in quest ion. For USD invest ments, usually US Treasur y
bills are used, while a common choice for EUR investments are German
government bills or Euribor rates. The mean r eal inter est r ate of US
treasury bills during the 20th century was 0.9% p.a. (Corresponding
figures for Germany are inapplicable due to hyperinflation during the
1920s.)
These securities are considered to be risk-free because the
likelihood of these governments defaulting is extremely low, and because
the short maturity of the bill protects the investor from interest-rate risk
that is present i n all fixed rate bonds (if interest rat es go up soon after
the bill is purchased, the investor will miss out on a fairly small amount
of interest before the bill matures and can be r einvested at the new
interest rate).
Since this interest rate can be obtained with no risk, it is implied
that any additional risk taken by an investor should be rewarded with an
8/8/2019 Security Market Line With Reference to Financial Firms in India

15
interest rate higher than the risk-free rate (on an after-tax basis, which
may be achieved with preferential tax treatment; some local government
US bonds give below the risk-free rate).
2.4.3 Non Diversifiable Risk of a Portfolio:
To understand why a certain amount of risk is always present in a
portfolio or the nature of the risk that cannot be diversified away
consider the case of ³n´ securities, the proportion of investment in each
security being 1/N-1 .The variance of the portfolio can be given by:
The residual risk in a well diversified portfolio equals the average
covariance of the securities in the portfolio representing the market risk.
This is the amount of ris k that cannot be diversified alway s no matter
how much diversification is done
2.4.4 Risk Decomposition:
The total risk of a security is measured in terms of variance or
standard deviation of its returns. Apart from this we know that the risk
comprises of both systematic and unsystematic components. The way or
method to split the total risk into the systematic or unsystematic risk
components is known as risk decomposition.
Here ¬2m = market variance.
im = Covariance of security i , and market index.
Vari ance (¬X2) = 1 (Rx - Rx)2 N-1

2.5 Beta
A measurement of the movement of the price of a particular stock
compared with the movement of the market as a whole over the same
period. If a stock has a beta value of less than 1, it is regarded as low
risk and if it has a beta of more than 1, it is regarded as more risky, but
there is a greater chance that it will outperform the market. Low beta
stocks are generally known as defensive stocks, such as food retailers,
and high beta stocks are more cyclical, in sectors such as consumer
durables. Betas are usually plotted on a scatter diagram which shows the
movement of the market as a whole and the return on a particular stock
daily, weekly, monthly or quarterly. Note that betas for any individual
company do change, so you can't rely on historical betas as a guide to
future betas, and a stock's beta varies according to the direction of the
market - some stocks are riskier in a falling market.
For example, Standard & Poor's 500 Index (S&P 500) has a beta
coefficient (or base) of 1. That means if the S&P 500 moves 2% in either
direction, a stock with a beta of 1 would also move 2%.
Under the same market conditions, however, a stock with a beta of
1.5 would move 3% (2% increase x 1.5 beta = 0.03, or 3%). But a stock
with a beta lower than 1 would be expected to be more stable in pric e

17
and move less. Betas as low as 0.5 and as high as 4 are fairly common,
depending on the sector and si ze of the company.
2.6 Literatur Review 1
S .K evin in his book ³ Portfolio Management ´ talks about
investment decisions and various ways to reduce risk and other points to
be noted before making an invest ment.
According to Kevin Return and risk are two important
characteristics of every investment. Investors base their investment
decision on the expected return and risk of investments. Risk is
measured by the variability in returns.
Investors attempt to reduce the variability of returns through
diversification of investment. This results in the creation of a portfolio.
With a given set of securities, any number of portfolios may be created
by altering the proportion of funds invested in each security. Among
these portfolios some dominate others or some are more efficient than
the vast majority of portfolios because of lower risk or higher returns.
Diversification helps to reduce risk, but even a well diversifie d
portfolio does not become risk free. If we construct a portfolio including
all the securities in the stock market, that would be the most diversified
portfolio. Even such a portfolio would be subject to considerable
variability. This variability is undiversifiable and is known as the market
risk or systematic risk because it affects all he securities in the market.

The real risk of a security is the market risk which cannot be
eliminated through diversification. This is indicated by the sensiti vity of
a security to the movements of the market and is measured by the beta
coefficient of the security.
A rational investor would expect the return on a security to be
commensurate with its risk. The higher the risk of security, the higher
would be the return expected from it. And since the relevant risk of a
security is its market risk or systematic risk, the return is correlated with
this risk only. The capital asset pricing model gives the nature of the
relationship between the expected return and the systematic risk of a
security.
2.7 Literatur Review 2
Charles P . Jones in the book ³ Investments -Analysis and
Management´ talks about importance of making a financial plan and
various methods & models used for investing.
According to Charles investment of funds in various assets is only
part of the over all financial decision making and planning that most
individuals must do. Before investing, each individual should develop an
overall financial plan. Such a plan should include the decision on
whether to purchase a house, which for most individuals represents a
major investment.
Investors should expect a risk premium for buying a risky asset
such as a stock. The greater the riskiness of that stock, the higher the
risk premium should be. If investors hold well-diversified portfolios,
they should be interested in portfolio risk rather than individual security

risk. Different stocks will affect a well diversified portfolio differently.
The relevant risk for an individual stock is its contribution to the
riskiness of a well diversified portfolio is market risk, or systematic
risk, which is nondiversifieable.
This chapter deals with data analysis using Capital Asset Pricing
Model and Security Market Line, for this 5 financial firms are chosen
and there actual return is calculated by taking its historical data and
finding mean return and risk associated with the stock.
Then the historical data of NSE (2007-2008) is taken to calculate
the mean return and betas of Market. Then by using the actual returns
and beta values expected returns are calculated by using Capital Asset
Pricing Model. Finally by comparing the actual returns with expected
returns pricing status of the stocks can be accessed. By using this
method the investor can decide wisely about his investm ent options in
stocks which would yield high return with calculated risk.

Covariance shows the degree to which the returns of the two
securities vary or change together.
1. The stocks which are having high value of covariance are
positively covariated means that the returns of the two securities
move in the same direction.
2. The stocks which are having lesser value of covariance or negative
covariance imply that the returns of the two securities move in the
opposite direction
3. Here the stock of LIC Housing Finance and India Bulls are highly
covariated with a covariance of 259.48 between them indicating
that the returns of these two stocks move in the same direction.
4. The securities of LIC Housing Finance and Bajaj Auto Finance are
having least value of covariance which implies that the returns of
these two stocks do not move in the same direction and hence may
be preferred combination to invest.

Table 4.2, coefficient of correlation between stocks
Coefficient of correlation reflects the degree of co movement
between two variables. Coefficient of correlation indicates the risk
aspect of the two stocks.
1. The correlation coefficient can vary between -1.0 and +1.0.
A value of -1.0 means perfect negative correlation or
co movement. A value of +1.0 means perfect correlation or
movement in the same direction.
2. The correlation coefficient between the securities of HDFC and
IDBI is the highest indicating high co movement
3. The correlation coefficient between the securities of LIC Housing
Finance and Bajaj Auto Finance is the lowest and hence the risk
will be least if investment is made in the combination of these two
securities.

1. From the above table it is found that the actual returns(2.10) of IDBI
are more than the expected returns(-86.14), and the beta (1.15)is more
than one which is considered to be high, but comparing to other
stocks it is having moderate risk.
2. India Bulls actual return (2.14) is also greater than expected return
(-95.58) and its beta (1.26) is quite high.
3. Bajaj Auto Finance Ltd. Has an actual return of -5.75 against an
expected return of -62.28, the beta is 0.86 which means the risk
associated with this stock is low.

4. HDFC¶s actual return (0.63) is greater than the expected return
(-74.83) and have a beta value of 1.07. which means the risk of the
stock is moderate.
5. LIC HSG Finance Ltd. Has an actual returns of 2.66 and an expected
return of -135.42, its beta value is 1.74. This is very high.
5.1 SUGGESTIONS
1. As it has been shown that the Market return is giving a negative
yield of -0.74 and the above said companies shares are under priced it
would be suggested to the investor to start investing.
2. As the returns of the stocks and the returns of the market are not
equal the market is considered to be very aggressive or volatile
3. As markets are very volatile and the returns for coming years is
not certain investor seeing for short term to medium term investment
(1 ± 5 yrs) are advised not t o invest in equity.
4. It¶s a good Opportunity for Investors looking for long term
Investment as stocks are available at lower prices, so it¶s the right time
to buy, but proper evaluat ion of companies is requir ed before investing
in them.
5. Seeing the current trend the volatility of the market is assumed to
continue for the next 18 to 24 months. So even though we may get stocks
at low prices there would be no increase in there value until 2years
(approximately).
6. Investors looking for long term investment in equity are advised to
invest in short term money instruments (Bank FD¶s etc) for 1-2 years and
8/8/2019 Security Market Line With Reference to Financial Firms in India
http://slidepdf.com/reader/full/security-market-line-with-reference-to-financial-firms-in-india 87/88
87
then systematically transfer some amount from these FD¶s into equity
over a period of ti me.
5.2 CONCLUSIONS
1. From the findings it is clear that the Actual Returns of all the
above companies specified are very high when compared to Expected
Returns. There is a wide gap between the Actual Return and the Expected
Return so it would be beneficial for the investor, as t he values of the
shares are under priced.
2. Investors investing in the above stocks are advised to invest in
combination of LIC Housing Finance and Bajaj Auto Finance as the
covariance & coefficient of coefficient between these stocks is less
which means that returns of these two stocks do not move in same
direction, and the risk will be least if investment is made in the
combination of these two.
3. So in terms of risk and return, combination of LIC Housing
Finance Limited and Bajaj Auto Finance would be an ideal combination
for investment.
