The document discusses key financial concepts including:
1) The primary goal of financial management is maximizing shareholder wealth through stock price appreciation. This is achieved by forecasting, investment decisions, coordination, and managing risk.
2) Risk is the probability that investment returns differ from expectations. There are various types of risk including market, business, liquidity, exchange rate, country, and interest rate risk.
3) Portfolio risk is determined not just by the risk of individual holdings, but also their covariance—how their returns move together. A portfolio's risk can be lower than its components' risks through diversification.
The document discusses risk and return in investments. It defines key concepts such as realized and expected return, ex-ante and ex-post returns, sources and measurements of risk including standard deviation and coefficient of variation. It also discusses the risk-return tradeoff and how higher risk investments require higher potential returns to compensate for additional risk.
This document defines key concepts related to risk and return in investments. It discusses components of return including yields and capital gains. It also defines expected return, relative return, and real rate of return. The document outlines several types of risk that can impact investments such as market risk, interest rate risk, liquidity risk, and foreign exchange risk. It also discusses standard deviation and the coefficient of variation as measures of risk. Finally, the capital asset pricing model is introduced as relating expected return on an asset to its systematic risk.
The document discusses the relationship between risk and return, known as the risk-return nexus. It defines key concepts like risk, return, systematic and unsystematic risk. It explains that total risk is comprised of systematic and unsystematic risk, but that unsystematic risk can be diversified away. The Capital Asset Pricing Model (CAPM) asserts that the expected return of an asset depends only on its systematic risk. Empirical analysis of CAPM shows strong correlation between market returns and the returns of various bonds, supporting the model.
This document discusses the relationship between risk and return in investments. It defines total risk as the sum of systematic and unsystematic risk. Systematic risk stems from external market factors that affect all investments, while unsystematic risk is specific to a particular company. The expected return and risk of individual stocks varies, with higher risk investments generally offering higher returns. A portfolio combines multiple assets to reduce overall risk through diversification. The portfolio risk depends on the covariance and correlation between the individual assets' returns. Diversifying across assets with low correlation is an effective way to reduce risk.

1) Total risk of a security is composed of systematic risk, which stems from external market factors, and unsystematic risk, which is specific to a company.
2) Diversifying a portfolio by holding many securities with returns that are not perfectly positively correlated can reduce total risk through lowering unsystematic risk exposure.
3) The degree of risk reduction from diversification depends on the correlation between the returns of the securities in the portfolio. Perfectly negatively correlated securities eliminate risk, while perfectly positively correlated securities do not allow for risk reduction through diversification.

1. The document discusses risk on portfolios and individual securities, as well as measures of risk like average absolute deviation and standard deviation.
2. It then explains the Capital Asset Pricing Model (CAPM), which relates expected return and systematic risk for assets. CAPM was developed by William Sharpe and considers both systematic and unsystematic risk factors.
3. The key elements of CAPM are outlined, including the capital market line, security market line, beta as a measure of individual asset risk compared to the market portfolio, and the CAPM formula.
Portfolio refers to a collection of investments held by an individual or institution. Portfolio management is the professional management of these securities and assets to meet investment goals. The portfolio management process involves creating an investment policy statement detailing goals and constraints, developing an investment strategy based on this, implementing the strategy by investing in assets, and monitoring the portfolio and updating the strategy over time as needs and markets change.
This document discusses the concept of time value of money and various time value of money calculations. It defines key concepts like future value, present value, perpetuity, net present value, etc. It provides examples to calculate future and present value of single amounts, annuities, multiple cash flows, and sinking funds. It also discusses the differences between annuities and annuities due. The document aims to explain the various time value of money principles and calculations for financial management and decision making.
Modern Portfolio Theory provides a framework for constructing investment portfolios to maximize expected return based on a given level of market risk. It assumes investors aim to reduce risk through diversification among assets with low correlations. Markowitz models show how to combine assets to obtain an efficient portfolio with the highest return for a given risk. Mean-variance optimization identifies the portfolio on the efficient frontier with the best risk-return tradeoff. However, the theory relies on historical data and assumptions that may not always hold in real markets.
1. The document discusses portfolio selection using the Markowitz model.
2. The Markowitz model aims to find the optimal portfolio, which provides the highest return and lowest risk. It does this by analyzing different combinations of securities to identify efficient portfolios.
3. The document provides details on the tools and steps used in the Markowitz model for portfolio selection, including analyzing expected returns, variance, standard deviation, and coefficients of correlation between securities.
The presentation discusses the profitability index (PI), which is a capital budgeting technique used to evaluate investment projects based on their profitability. The PI is calculated as the discounted cash inflows divided by the initial cash outflow. A PI greater than or equal to 1 indicates the project is profitable. The presentation provides an example calculation of the PI for a project with an initial investment of $200,000 and cash flows of $40,000, $30,000, $50,000 and $20,000 over 4 years with a 10% discount rate, resulting in a PI of 1.1235.
This document provides an introduction to key concepts in corporate finance including what corporate finance is, its relationship to financial accounting and management accounting, the concepts of risk and return and time value of money. It discusses corporate structure including sole proprietorships, partnerships and corporations. It describes the finance function and role of the financial manager in raising, allocating and returning funds. It also covers separation of ownership and management and issues of agency theory and corporate governance.

Portfolio Mgt Ch 01 The Investment SettingSalik Sazzad
This document discusses key concepts related to investment analysis and portfolio management. It defines key terms like real rate of return, inflation premium, and risk premium. It also covers topics like measuring historical rates of return using holding period return and equivalent annual return. The document discusses measuring risk using standard deviation and beta. It explains that the required rate of return on an investment is determined by the real risk-free rate, expected inflation, and the risk premium required for the investment's inherent risk.
This chapter discusses risk and return, including:
- Risk and return of individual assets is measured using probability distributions and expected return and standard deviation.
- Portfolio risk is lower than holding individual assets due to diversification. Beta measures the sensitivity of an asset's return to market movements.
- The Security Market Line shows the expected return of an asset based on its beta and the risk-free rate. The Capital Asset Pricing Model suggests assets should be priced based on their systematic risk.
Because of the risk-return tradeoff, you must be aware of your personal risk tolerance when choosing investments for your portfolio. Taking on some risk is the price of achieving returns; therefore, if you want to make money, you can't cut out all risk. The goal instead is to find an appropriate balance - one that generates some profit, but still allows you to sleep at night.

This document discusses various concepts related to investment returns and risk. It begins by defining return as income received plus capital gains. It then discusses the components of return including yield and capital gains. It provides a formula to calculate total return. The document then discusses various types of risk including market risk, liquidity risk, and foreign exchange risk. It also covers sensitivity analysis using range and standard deviation. Finally, it discusses portfolio returns and risks, and introduces the Capital Asset Pricing Model to relate expected returns to market risk.
The document provides an overview of security analysis and different analytical techniques used, including fundamental analysis and technical analysis.
Fundamental analysis involves analyzing the economy, industry, and company to determine a company's intrinsic value. Technical analysis uses historical price and volume data to identify trends and patterns that can predict future price movements. Key techniques include chart analysis and identifying support/resistance levels and patterns like head and shoulders. The efficient market hypothesis suggests stock prices already reflect all available public information and it is difficult to outperform the overall market through analysis alone.
This document discusses the valuation of bonds and shares. It defines intrinsic value as the present value of expected future cash flows from an asset, discounted by the required rate of return. Book value is the value of an asset on the balance sheet, calculated as cost minus accumulated depreciation. The document outlines different types of bonds such as irredeemable and redeemable bonds, and how to calculate the present value of bonds with annual and semi-annual interest payments using discounted cash flow formulas. An example calculation is provided.
The document discusses various concepts related to security risk and return, including:
1. Calculating returns from security investments
2. Understanding historical return and risk
3. Efficient market hypothesis and its implications
4. Calculating expected returns and the impact of diversification on risk
It also covers risk-return tradeoff, systematic risk, security market line, and using the Capital Asset Pricing Model.

1) Return is the income received from an investment plus any change in the market price expressed as a percentage of the beginning market price. It measures the profit or loss over a period of time.
2) Risk is the variability of returns compared to expected returns. Higher variability means higher risk. Standard deviation is commonly used to measure the risk of an investment.
3) Portfolio expected return is calculated by weighting the expected return of each individual asset by its proportion in the portfolio. Portfolio risk is measured by standard deviation which takes into account the covariances between assets. Diversification reduces unsystematic risk.

The document discusses risk and return in investments. It defines key concepts like holding period return (HPR), expected return, standard deviation, variance, and coefficient of variation. It provides examples of calculating HPR for stocks based on purchase price, selling price, and dividends. Expected return is the average HPR and can be calculated in different ways. Risk is the variability in returns and can be measured using standard deviation, variance, beta, etc. The document also discusses portfolio returns and how to calculate expected portfolio return based on individual asset expected returns and weights.
This document discusses key concepts in portfolio theory, including how to calculate investment returns over single and multiple periods. It defines holding period return (HPR) to measure single period returns and arithmetic average, geometric average, and dollar-weighted return to measure returns over many periods. It also explains how to calculate the expected return, variance, and standard deviation of investments to quantify the expected reward and risk.
This document defines key concepts related to investment returns including yield, capital gains, total return, expected return, relative return, real/inflation-adjusted return, and risk. It discusses components of return including yield and capital gains. Total return is defined as the sum of yield and price change. Expected return is the weighted average of possible returns based on their probabilities. Relative return compares an investment's return to a benchmark. Real return removes the effects of inflation from the nominal return. Risk is defined as the variability between expected and actual returns, and various types of risk are described such as market risk and liquidity risk. Methods for analyzing risk including sensitivity analysis, standard deviation, and coefficient of variation are also summarized.
The Capital Asset Pricing Model (CAPM) formalizes the relationship between risk and expected return. It states that the expected return of an asset is determined by its sensitivity to non-diversifiable or systematic risk as measured by its beta. Beta measures how an asset's returns co-vary with the market portfolio. According to CAPM, an asset's expected return is equal to the risk-free rate plus its beta multiplied by the market risk premium. Diversification reduces risk by eliminating asset-specific or diversifiable risk, but not market risk.

The document discusses portfolio management and various approaches to constructing portfolios. It defines a portfolio as a combination of different asset classes like stocks, bonds, and money market instruments. The traditional approach to portfolio construction evaluates an individual's overall financial plan and objectives to determine suitable securities. The modern approach uses the Markowitz model to maximize expected return for a given level of risk. This models constructs portfolios along the "efficient frontier" where higher returns are achieved for the same level of risk. Factors like diversification, correlation between assets, and an individual's risk tolerance further influence portfolio selection.
The document discusses key concepts related to risk and return in investments. It defines return as the motivating force for making investments, while risk refers to uncertainty in future cash flows. There are different types of returns such as historical returns and expected returns. Risk is measured using concepts like variance, standard deviation, and beta. The Capital Asset Pricing Model relates risk and return, specifying that expected return is equal to the risk-free rate plus a risk premium based on systematic risk. Diversification can reduce unsystematic risk but not systematic risk.

This document discusses risk and return, including key concepts such as:
- Risk is defined as the potential variability in investment returns, while return refers to the total gain or loss on an investment.
- There is typically a relationship between higher risk and higher potential returns.
- Standard deviation and beta are common measures used to quantify investment risk. Beta specifically measures the volatility of a security compared to the overall market.
- Portfolio risk can be reduced through diversification among assets with low or negative correlations. However, some systematic market risk cannot be diversified away.
- The Capital Asset Pricing Model (CAPM) describes the expected return of an asset based on its beta and the expected market return.
International Portfolio Investment and Diversification2.pptxVenanceNDALICHAKO1
Portfolio management involves making investment decisions about asset allocation to balance risk and return for individuals and institutions. A portfolio is a group of financial assets such as stocks and bonds. Portfolio investments are passive and made with the goal of earning returns. Risk is reduced through diversification across many assets whose returns are not perfectly correlated. The expected return of a portfolio is the weighted average of the expected returns of its individual components, weighted by their proportion in the portfolio. Portfolio risk comes from asset-specific and systematic sources and can be measured by the variance and standard deviation of returns. Diversification reduces asset-specific risk but not systematic risk.
Security analysis and portfolio managementFinSubham
This document discusses security analysis and portfolio management. It defines key concepts like systematic risk, market risk, interest rate risk, purchasing power risk, and exchange rate risk. It also explains how to calculate measures like beta, variance, and covariance that are used to evaluate risk and return of investment portfolios. The goal is to construct efficient portfolios that maximize return for a given level of risk based on Markowitz portfolio theory.
The document discusses risk and return, including expected return, variance, and standard deviation. It provides examples of how to calculate expected return by taking the returns of individual outcomes and multiplying by their probabilities. It also explains how to calculate variance and standard deviation as measures of risk and dispersion around the mean. The standard deviation is the square root of the variance and provides a measure of risk in the same units as the data. Riskier investments are expected to provide higher returns through a risk premium.
This chapter discusses portfolio theory and the benefits of diversification. It introduces the concept of the efficient frontier, which graphs the set of optimal portfolios that maximize expected return for a given level of risk. The chapter also discusses measuring risk and return of portfolios, the single index model, and how introducing a risk-free borrowing and lending opportunity shifts the efficient frontier. The optimal portfolio is found where the efficient frontier is tangent to an investor's indifference curve.
This document discusses risk and return, defining risk as the potential divergence between actual and expected outcomes. It outlines measures of return such as dollar return, percentage return, and holding period return. Risk is measured using standard deviation, which indicates how spread out returns are from the mean. Higher standard deviation means higher risk. Charts of market indexes like the Dow Jones Industrial Average show the volatility of returns over time.
This document discusses risk and return, defining risk as the potential divergence between actual and expected outcomes. It presents data on market indexes like the Dow Jones Industrial Average, NASDAQ, and S&P/TSX over time, showing fluctuations. It then covers calculating returns, including dollar returns, percentage returns, and holding period returns. Risk is measured using standard deviation, which captures how spread out returns are from the mean. The relationship between risk and return is important for investors, corporations, and financial intermediaries.

Risk & return cf presentaion
1. The primary financial goal is shareholder wealth
maximization, which translates to maximizing stock
price.
Maximize stock value by:
◦ Forecasting and planning
◦ Investment and financing decisions
◦ Coordination and control
◦ Transactions in the financial markets
◦ Managing risk
1
2. It is the reward for undertaking the investment
The Two Components of Return
1. Yield: The income component of a security’s return
2. Capital gain (loss): The change in price on a
security over some period of time
Putting The Two Components Together
Total return = Yield + Price change
Where: the yield components can be 0 or +
the price change components can be 0, +, or -

3. “Risk comes from not knowing what you are doing”
Warren Buffet
The chance that the actual outcome from an
investment will differ from the expected outcome.
Future returns from an investment are unpredictable
Risk = Probability of occurrence * Impact on objects

6. Total Return (TR)
Percentage measure relating all cash flows on a
security for a given time period to its purchase price
TR= Any cash payment received + Price change over the period
Price at which the asset is purchased
How to Calculate Total Return
TR= CFt +(PE - PB) = CFt +PC
PB PB

7. Example: 100 shares of data shield are purchased at
$30 per share and sold one year later at $35 per
share. A dividend of $2 per share is paid.
Stock TR = 2+(35-30)/30
= 2+(5)/30
= 0.2333 or 23.33%

8. Example: Assume the purchase of a 10% coupon
Treasury bond at a price of $960, held 1 year, and
sold for $1020. The TR is
Bond TR = 100+(1020-960)/960
= 100+60/960
= 0.1667 or 16.67%

The future is uncertain.
Investors do not know with certainty whether the
economy will be growing rapidly or be in recession.
Investors do not know what rate of return their
investments will yield.
Therefore, they base their decisions on their
expectations concerning the future.
The expected rate of return on a stock represents
the mean of a probability distribution of possible
future returns on the stock.
13. 13
Given a probability distribution of returns, the
expected return can be calculated using the
following equation:
N
E[R] = S (piRi)
i=1
Where:
◦ E[R] = the expected return on the stock
◦ N = the number of states
◦ pi = the probability of state i
◦ Ri = the return on the stock in state i.
14. 14
Risk reflects the chance that the actual return on an
investment may be different than the expected
return.
One way to measure risk is to calculate the variance
and standard deviation of the distribution of
returns.
Var(R) = s2 = S pi(Ri – E[R])2
i=1
Where:
◦ N = the number of states
◦ pi = the probability of state i
◦ Ri = the return on the stock in state i
◦ E[R] = the expected return on the stock
15. 15
The standard deviation is calculated as the positive
square root of the variance:
SD(R) = s = s2 = (s2)1/2 = (s2)0.5
16. The ratio of the standard deviation of a
distribution to the mean of that distribution.
It is a measure of RELATIVE risk.
CV =s/E(R)

The variance and standard deviation for stock X is calculated as
follows:
E[R]X = .2(5%) + .3(10%) + .3(15%) + .2(20%) = 12.5%
s2
X = .2(.05 -.125)2 + .3(.1 -.125)2 + .3(.15 -.125)2 + .2(.2 -.125)2
= .002625
sX = (.002625)0.5 = .0512 = 5.12%
CV = 5.12/12.5 = 0.41
21. 21
E[R]Y = .2(50%) + .3(30%) + .3(10%) + .2(-10%) =20 %
s2
y = .2(.50 -.20)2 + .3(.30 -.20)2 + .3(.10 -.20)2 + .2(-.10 -
.20)2 = .042
sy = (.042)0.5 = .2049 = 20.49%
CV = 20.49 / 20 = 1.09
Although Stock Y offers a higher expected return than Stock X, it
is also riskier since its variance and standard deviation are greater
than Stock X's.
22. Certainty Equivalent (CE) is the amount of cash
someone would require with certainty at a point
in time to make the individual indifferent
between that certain amount and an amount
expected to be received with risk at the same
point in time.
23. Certainty equivalent > Expected value
Risk Preference
Certainty equivalent = Expected value
Risk Indifference
Certainty equivalent < Expected value
Risk Aversion
Most individuals are Risk Averse.
24. You have the choice between (1) a
guaranteed dollar reward or (2) a coin-flip
gamble of $100,000 (50% chance) or $0
(50% chance). The expected value of the
gamble is $50,000.
•Mary requires a guaranteed $25,000, or more, to
call off the gamble.
•Raleigh is just as happy to take $50,000 or take
the risky gamble.
•Shannon requires at least $52,000 to call off the
gamble.
Risk Attitude Example
25. What are the Risk Attitude tendencies of each?
Mary shows “risk aversion” because her
“certainty equivalent” < the expected value of
the gamble.
Raleigh exhibits “risk indifference” because her
“certainty equivalent” equals the expected value
of the gamble.
Shannon reveals a “risk preference” because her
“certainty equivalent” > the expected value of
the gamble.

The Expected Return on a Portfolio is the weighted average of the
expected returns on the stocks which comprise the portfolio.
This can be expressed as follows:
N
E[Rp] = S wiE[Ri]
i=1
Where:
◦ E[Rp] = the expected return on the portfolio
◦ N = the number of stocks in the portfolio
◦ wi = the proportion of the portfolio invested in stock i
◦ E[Ri] = the expected return on stock i
28. 28
The variance/standard deviation of a portfolio reflects not only the
variance/standard deviation of the stocks that make up the portfolio but also how
the returns on the stocks which comprise the portfolio vary together.
◦ Covariance is a measure that combines the variance of a stock’s returns with
the tendency of those returns to move up or down at the same time other
stocks move up or down.
◦ Correlation coefficient, is often used to measure the degree of co-movement
between two variables. The correlation coefficient simply standardizes the
covariance.
◦ Its range is from –1.0 (perfect negative correlation), through 0 (no
correlation), to +1.0 (perfect positive correlation).
29. 29
The Covariance between the returns on two stocks can be
calculated as follows:
N
Cov(RX,RY) = sX,Y = S pi(RXi - E[RX])(RYi - E[RY])
i=1
Where:
◦ sX,Y = the covariance between the returns on stocks X and Y
◦ N = the number of states
◦ pi = the probability of state i
◦ RXi = the return on stock X in state i
◦ E[RX] = the expected return on stock X
◦ RYi = the return on stock Y in state i
◦ E[RY] = the expected return on stock Y
30. 30
The Correlation Coefficient between the returns on two stocks can
be calculated as follows:
sX,Y
Corr(RX,RY) = rX,Y = sX sy
Where:
◦ rX,Y =the correlation coefficient between the returns on stocks X
and Y
◦ sX,Y =the covariance between the returns on stocks X and Y,
◦ sX =the standard deviation on stock X, and
◦ sy =the standard deviation on stock Y
31. 31
The covariance between stock X and stock Y is as
follows:
sX,Y = .2(.05-.125)(.5-.2) + .3(.1-.125)(.3-.2) +
.3(.15-.125)(.1-.2) +.2(.2-.125)(-.1-.2) = -.0105
The correlation coefficient between stock X and stock
Y is as follows:
-.0105
rX,Y = (.0512)(.2049) = -1.00
32. 32
Most investors do not hold stocks in isolation.
Instead, they choose to hold a portfolio of several stocks.
When this is the case, a portion of an individual stock's risk
can be eliminated, i.e., diversified away.
From our previous calculations, we know that:
◦ the expected return on Stock X is 12.5%
◦ the expected return on Stock Y is 20%
◦ the variance on Stock X is .00263
◦ the variance on Stock Y is .04200
◦ the standard deviation on Stock X is 5.12%
◦ the standard deviation on Stock Y is 20.49%
33. 33
Using either the correlation coefficient or the
covariance, the Variance on a Two-Asset Portfolio can
be calculated as follows:
s2
p = (wA)2s2
x + (wy)2s2
y + 2wxwy rX,Y sxsy
OR
s2
p = (wA)2s2
x + (wy)2s2
y + 2wxwy sx,y
The Standard Deviation of the Portfolio equals the
positive square root of the variance.

39. While diversification of portfolio, there are
two kinds of risk we will deal with:
- Unsystematic Risk
- Systematic Risk
- So,
Total Risk = Unsystematic Risk + Systematic
Risk
40. An unsystematic risk, also called diversifiable,
unique, firm specific risk, is one that is particular
to a single asset or, at most, a small group.
For example, if the asset under consideration is
stock in a single company,
- The positive NPV projects( successful new
products, cost saving) will tend to increase the
value of stock.
- Unanticipated lawsuits, industrial accidents,
strikes etc will decrease the FCF’s and thereby
decrease the share values.
41. Unsystematic risk is essentially eliminated by
diversification, so a portfolio with many
assets has almost no unsystematic risk.
42. Systematic risk, also called as undiversifiable,
unavoidable, market risk, is due to factors that
affect overall market, such as,
- Changes in nation’s economy
- Tax reforms
- Change is world energy situation
These are the risks that affect securities overall(
whether in a portfolio or single) and,
consequently, cannot be diversified away.
An investor who holds a well-diversified portfolio
will be exposed to this type of risk.
44. The systematic risk principle states that the
reward for bearing risk depends only on the
systematic risk of an investment.
- The underlying rationale for this principle is
straight forward: because unsystematic risk
can be eliminated at virtually no cost(by
diversifying), there’s no reward for bearing it.
- No matter how much total risk an asset has,
only the systematic risk is relevant
determining the expected return and risk
premium on that asset.
45. Beta is an index of systematic risk.
Beta (β) of a stock or portfolio is a number
describing the relation of its returns with those
of the market as a whole.
The sensitivity of an asset’s return on the market
index.
A measure of the volatility, or systematic risk, of
a security or a portfolio in comparison to the
market as a whole.
Beta is a standardized measure of the covariance
of the asset’s return with the market return.
45
46. Beta = Covariance of Asset’s return with
market return / variance of market return
= Cov im/ s2
m
The beta of a portfolio is simply a weighted
average of the individual stock betas in the
portfolio.
47. 47
bp = Weighted average
= 0.5(bX) + 0.5(bY)
= 0.5(1.29) + 0.5(-0.86)
= 0.22
48. The typical analysis involves either monthly or weekly returns
on the stocks and on the market index for 3-5 years.
Many analysts use the S&P 500 to find the market return.
Analysts typically use four or five years’ of monthly returns to
establish the regression line like Merill Lynch.
Some analysts use 52 weeks of weekly returns like Value
Line.

49. •Obtaining Betas
• Can use historical data if past best represents
the expectations of the future.
•Adjusted Beta
• There appears to be a tendency for the
measured betas of individual securities to
revert eventually toward the beta of the market
portfolio.
• This might be due to the economic factors
affecting the operations and financing of the
firm.
50. A line that describes the relationship between an individual
security’s returns and returns on the market portfolio.
It is useful to deal with returns in excess of the risk free rate.
The excess return is simply the expected return less the risk
free return.
There are two ways of determining the relationship b/w
excess return on stock and market portfolio.
- Historical data (with the assumption that relationship will
continue in future)
- Security Analysts.

52. Greater the slope, greater the systematic risk.
Alpha is intercept of characteristic line on vertical
axis.
If excess returns for market portfolio were zero,
alpha would be the expected excess return for
the stock.
Beta is slope of characteristic Line = Rise/Run
i.e. Change in Stock’s Return/ Change in Market
Return
The monthly returns are calculated as:
(Div paid) + (Ending price – beginning price)/
Beginning price

Each characteristic
line has a
different slope.
Characteristic Lines and Different Betas
54. Aggressive Investment: A slope steeper than
1 means that the stock’s excess return varies
more than proportionally with the excess
return of market portfolio, it has more
systematic risk than market.
Defensive Investment: A slope less than 1
means that the stock’s excess returns varies
less than proportionally with the excess
return of the market portfolio. It has less
systematic risk than market.
55. If b = 1.0, stock has average risk.
If b > 1.0, stock is riskier than average.
If b < 1.0, stock is less risky than average.
Most stocks have betas in the range of 0.5 to 1.5.
A positive beta means that the asset's returns generally follow
the market's returns, in the sense that they both tend to be
above their respective averages together, or both tend to be
below their respective averages together.
A negative beta means that the asset's returns generally move
opposite the market's returns: one will tend to be above its
average when the other is below its average

56. The CAP model was introduced by Jack Treynor, John
Lintner, William Sharpe and Jan Mossin in the early
1960’s.
According to CAP model the investor needs to be
compensated in two ways, for time value of money
(risk free rate) and for taking systematic risk.
In a competitive market, the expected risk premium
varies in direct proportion to beta.
This model states the linear relationship between risk
(systematic) and expected (required) return.
A security’s expected return is risk free rate plus a
premium based on the systematic risk of security.
Rj = Rf + bj(RM – Rf)
57. Capital markets are efficient.
Homogeneous investor expectations over a given period.
Investors all think in terms of a single holding period.
There are no taxes and no transactions costs.
All investors are price takers, that is, investors buying and
selling won’t influence stock prices.
Quantities of all assets are given and fixed.
Risk-free asset return is certain.
Market portfolio contains only systematic risk (use S&P
500 Index or similar as a proxy).
Investors can borrow or lend unlimited amounts at the
risk-free rate.
58. The least risky investment is T-bills, since the
return on them is fixed, it is unaffected by
what happens to the market. (beta = 0),
The riskier investment is market portfolio of
common stocks (average beta = 1)
Risk premium(excess return) is expected
returns minus risk free return.
The relationship between systematic risk and
expected return in financial markets is
usually called the security market line (SML).
59. The relationship between an individual security’s expected
rate of return and it’s systematic risk as measured by beta
will be linear, this relationship is called as Security Market
Line.

Systematic Risk (Beta)
60. Now, if everyone holds the market portfolio,
and if beta measures each security’s
contribution to the market portfolio risk, then
it’s no surprise that the risk premium
demanded by investors is proportional to
beta.
This is what the CAPM says!
62. Investors require some extra return for taking
risk, that is why common stocks are given
higher returns on average than t-bills.
Investors are not concerned with those risks
that they cannot diversify, hence the
systematic risk the relevant risk only.
63. Maturity of Risk free Security :
CAPM is one period model and investors are
concerned about the long term capital
investment returns.
Faulty use of the market index
CAPM/SML concepts are based on
expectations, yet betas are calculated using
historical data. A company’s historical data
may not reflect investors’ expectations about
future riskiness.
