SECURITY ANALYSIS AND PORTFOLIO MANAGEMENT
Time Allowed: 3 Hours Maximum Marks: 50
Note: Aempt Five quesons in all, selecng at least One queson from each secon. The
Fih queson may be aempted from any secon. All quesons carry equal marks.
SECTION-A
1. Explain the concept of risk. What are various stascal methods to measure risk?
Ans: 1. What is Risk?
In simple words, risk means the possibility of loss or uncertainty of returns.
Whenever we make a decision about the futurelike investing, starting a business, or even
choosing a careerwe face risk because the future is unknown.
Example:
Easy2Siksha.com
If you invest ₹10,000 in a stock, it may grow to ₹15,000 (profit)
Or it may fall to ₹7,000 (loss)
Since you don’t know the exact outcome, there is risk involved.
2. Key Features of Risk
To understand risk better, remember these important points:
Uncertainty: Risk exists because the future is unpredictable
Possibility of Loss: There is always a chance of negative outcomes
Variability: Outcomes can differ from expectations
Decision-based: Risk arises when we make choices
󷷑󷷒󷷓󷷔 In short:
Higher uncertainty = Higher risk
3. Types of Risk (Basic Idea)
Before measuring risk, it's useful to know that risk can be of different types:
Business Risk: Loss due to poor business performance
Financial Risk: Risk from loans or debt
Market Risk: Changes in stock prices
Personal Risk: Illness, accidents, etc.
4. Statistical Methods to Measure Risk
Now comes the important part:
How do we measure risk?
Since risk is about uncertainty, we use statistics to measure how much outcomes vary.
(1) Range (Simplest Method)
Range shows the difference between the highest and lowest possible outcomes.
󹵙󹵚󹵛󹵜 Formula:
Range = Maximum Value Minimum Value
Easy2Siksha.com
Example:
Returns are: 5%, 10%, 15%
Range = 15% 5% = 10%
󷷑󷷒󷷓󷷔 Meaning:
Higher range = Higher risk
Easy to calculate
󽆱 But not very accurate (ignores other values)
(2) Variance (More Accurate Method)
Variance measures how far each value is from the average (mean).
𝜎
2
=
∑(𝑥𝑥ˉ)
2
𝑛
󷷑󷷒󷷓󷷔 Meaning:
If values are spread out → High variance → High risk
If values are close → Low variance → Low risk
Uses all data
󽆱 Slightly complex
(3) Standard Deviation (Most Popular Method)
This is the square root of variance and is widely used in finance.
𝜎=
∑(𝑥𝑥ˉ)
2
𝑛
󷷑󷷒󷷓󷷔 Meaning:
Higher standard deviation = Higher risk
Lower standard deviation = More stable returns
Most reliable and commonly used
Easy to interpret compared to variance
Easy2Siksha.com
(4) Coefficient of Variation (CV)
This method compares risk relative to return.
𝐶𝑉=
𝜎
𝑥ˉ
×100
󷷑󷷒󷷓󷷔 Meaning:
Lower CV = Better (less risk per unit of return)
Higher CV = More risk
Useful for comparing different investments
(5) Beta (β) – Market Risk Measure
Beta measures how much an investment reacts to market changes.
β = 1 → Same as market
β > 1 → More risky than market
β < 1 → Less risky
󷷑󷷒󷷓󷷔 Example:
If the market rises 10% and your stock rises 15%, it has high beta (more risk).
(6) Probability Distribution
This method studies the likelihood of different outcomes.
󷷑󷷒󷷓󷷔 Example:
20% chance of loss
50% chance of moderate gain
30% chance of high gain
Helps in understanding all possible outcomes
5. Simple Summary
Let’s quickly revise:
Risk = Uncertainty + Possibility of Loss
Easy2Siksha.com
It is present in every financial decision
It is measured using statistical tools
Main Methods:
Range → Basic idea
Variance → Spread of data
Standard Deviation → Most important
Coefficient of Variation → Comparison tool
Beta → Market risk
Probability → Chances of outcomes
Conclusion
Risk is a natural part of life and decision-making. Whether you are investing money, starting
a business, or making career choices, you cannot avoid riskbut you can understand and
measure it.
Statistical methods like standard deviation and variance help us turn uncertainty into
numbers, making it easier to compare options and make better decisions.
2. Explain various methods of markeng of securies in detail.
Ans: 󹵈󹵉󹵊 Methods of Marketing Securities
When a company needs money to expand, modernize, or launch new projects, it often turns
to the capital market. Marketing securities means selling shares, debentures, or bonds to
investors. Let’s explore the major methods in detail:
1. Pure Prospectus Method
The company issues a detailed prospectus explaining its business, financials, and
purpose of raising funds.
Investors can directly subscribe to shares.
Advantage: Transparent and informative.
Disadvantage: Costly and time-consuming due to legal formalities.
2. Offer for Sale Method
The company sells securities to intermediaries (like brokers or financial institutions),
who then resell them to the public.
Advantage: Reduces burden on the company.
Easy2Siksha.com
Disadvantage: Investors may pay higher prices due to middlemen.
3. Private Placement Method
Securities are sold directly to select investors such as banks, insurance companies, or
wealthy individuals.
Advantage: Quick and less expensive.
Disadvantage: Limited to a small group, not accessible to the general public.
4. Initial Public Offer (IPO)
The company invites the public to buy shares for the first time.
Advantage: Raises large funds, increases visibility.
Disadvantage: Requires strict compliance with regulations.
5. Rights Issue Method
Existing shareholders are given the “right” to buy additional shares at a discounted
price.
Advantage: Rewards loyal shareholders.
Disadvantage: New investors cannot participate.
6. Bonus Issue Method
Free shares are issued to existing shareholders from company reserves.
Advantage: Boosts shareholder confidence.
Disadvantage: No fresh funds are raised.
7. Book-Building Method
Investors bid for shares within a price range, and the final price is decided based on
demand.
Advantage: Reflects true market demand.
Disadvantage: Complex process requiring expert management.
8. Stock Option Method
Employees are given the option to buy company shares at a fixed price.
Advantage: Motivates employees, aligns their interests with company growth.
Disadvantage: Limited to employees, not a fundraising tool for the public.
9. Bought-Out Deals Method
An investment institution buys the entire issue from the company and later sells it to
the public.
Advantage: Immediate funds for the company.
Disadvantage: Company loses control over pricing and timing.
Easy2Siksha.com
󽀼󽀽󽁀󽁁󽀾󽁂󽀿󽁃 Advantages of Multiple Methods
Flexibility: Companies can choose based on their needs.
Accessibility: Different methods reach different investor groups.
Efficiency: Some methods are faster, others more transparent.
󽁔󽁕󽁖 Disadvantages
Complexity: Legal and regulatory hurdles.
Costs: Prospectus and IPOs are expensive.
Limited Reach: Private placements exclude small investors.
󷈷󷈸󷈹󷈺󷈻󷈼 Conclusion
Marketing securities is like choosing the best way to sell a product. Sometimes you go
directly to customers (prospectus, IPO), sometimes through dealers (offer for sale, bought-
out deals), and sometimes you reward loyal customers (rights and bonus issues). Each
method has its own purpose, advantages, and drawbacks.
SECTION-B
3. Dierenate between technical analysis and fundamental analysis. Would you advise an
investor to use only technical analysis for investment decision making
Ans: 󹼧 What is Fundamental Analysis?
Fundamental analysis focuses on the real value of a company.
It tries to answer:
󷷑󷷒󷷓󷷔 “Is this company actually strong and worth investing in?”
An investor studies things like:
Company profits and revenue
Assets and liabilities
Management quality
Industry growth
Economic conditions
󹵙󹵚󹵛󹵜 Example:
If a company is making good profits, growing steadily, and has strong management, it is
considered a good long-term investment.
Easy2Siksha.com
󷷑󷷒󷷓󷷔 In simple words:
Fundamental analysis = Studying the “health” of the company
󹼧 What is Technical Analysis?
Technical analysis focuses on price movements and charts, not the company itself.
It tries to answer:
󷷑󷷒󷷓󷷔 “When is the right time to buy or sell?”
An investor studies:
Price charts
Trends (uptrend, downtrend)
Patterns (like head & shoulders)
Indicators (RSI, MACD, moving averages)
󹵙󹵚󹵛󹵜 Example:
If a stock price is rising continuously and showing a strong trend, a technical analyst may
say:
󷷑󷷒󷷓󷷔 “Buy now, momentum is strong.”
󷷑󷷒󷷓󷷔 In simple words:
Technical analysis = Studying “market behavior” and price patterns
󹼧 Key Differences (Easy Comparison)

󹼧 Which One is Better?
Now comes the important part of your question.
󷷑󷷒󷷓󷷔 Should an investor rely only on technical analysis?
Easy2Siksha.com
The simple answer is:
󽆱 No, relying only on technical analysis is not advisable.
Let’s understand why.
󹼧 Why Only Technical Analysis is Risky
1. It ignores real company value
A stock may look good on charts, but the company might be weak.
󷷑󷷒󷷓󷷔 Example:
A company with poor financial health may still show a temporary price rise.
2. Market emotions can mislead
Technical analysis is based on market psychology, which can change quickly.
󷷑󷷒󷷓󷷔 Prices may rise due to hype, not real strength.
3. No long-term security
Technical analysis is mostly useful for short-term trading, not long-term wealth creation.
󹼧 Why Fundamental Analysis is Important
Fundamental analysis helps you:
Invest in strong companies
Reduce long-term risk
Build wealth over time
󷷑󷷒󷷓󷷔 Great investors like Warren Buffett mainly use fundamental analysis.
󹼧 The Best Approach (Smart Strategy)
Instead of choosing one, smart investors use both together.
Easy2Siksha.com
󷷑󷷒󷷓󷷔 This is called a combined approach:
Use Fundamental Analysis → to choose the right company
Use Technical Analysis → to decide the right time to buy/sell
󹵙󹵚󹵛󹵜 Example:
You find a strong company (fundamental)
Then wait for a good entry point using charts (technical)
󹼧 Final Conclusion
Fundamental analysis tells you “what to buy”
Technical analysis tells you “when to buy”
󷷑󷷒󷷓󷷔 So, relying only on technical analysis is not a wise decision, especially for long-term
investors.
4. Crically examine the features of Capital Asset Pricing Model. What are the
assumpons of this model?
Ans: 󷊆󷊇 Understanding CAPM
The Capital Asset Pricing Model (CAPM) is a formula that helps investors decide whether a
stock or asset is worth investing in, given its risk compared to the overall market.
The formula is:
𝐸(𝑅
𝑖
)=𝑅
𝑓
+𝛽
𝑖
(𝑅
𝑚
𝑅
𝑓
)
Where:
𝐸(𝑅
𝑖
)= Expected return on the asset
𝑅
𝑓
= Risk-free rate (like government bonds)
𝛽
𝑖
= Beta (measures how risky the asset is compared to the market)
𝑅
𝑚
= Expected market return
In simple terms, CAPM says: Your return should equal the safe return plus extra
compensation for taking risk.
󽁗 Features of CAPM
1. Risk-Return Relationship
Easy2Siksha.com
o CAPM directly connects risk (beta) with expected return.
o Higher risk → higher expected return.
2. Beta as a Key Measure
o Beta shows how sensitive a stock is to market movements.
o Example: A beta of 1.5 means the stock is 50% more volatile than the market.
3. Market-Oriented
o CAPM assumes investors compare every asset to the overall market portfolio.
4. Simplicity
o Provides a straightforward formula for calculating expected returns.
5. Cost of Equity Estimation
o CAPM is widely used by companies to estimate the cost of equity when
making investment decisions.
6. Focus on Systematic Risk
o CAPM only considers systematic risk (market-wide risk), not unsystematic risk
(company-specific risk).
󷘹󷘴󷘵󷘶󷘷󷘸 Assumptions of CAPM
CAPM is built on several assumptions, which make it elegant but also unrealistic:
1. Investors are Rational and Risk-Averse
o Assumes all investors make logical decisions and prefer less risk.
2. Perfect Capital Market
o No transaction costs, taxes, or restrictions.
3. Homogeneous Expectations
o All investors have the same expectations about returns, risks, and future
performance.
4. Risk-Free Borrowing and Lending
o Investors can borrow or lend unlimited money at the risk-free rate.
5. Single Period Investment Horizon
o Assumes investors plan for only one period (like one year).
6. Market Portfolio is Efficient
o Assumes all investors hold a mix of assets that perfectly represents the
market.
7. Only Systematic Risk Matters
o Company-specific risks can be diversified away, so only market risk affects
returns.
󽀼󽀽󽁀󽁁󽀾󽁂󽀿󽁃 Criticisms of CAPM
While CAPM is elegant, it faces criticism:
Unrealistic Assumptions: Real markets have taxes, transaction costs, and irrational
investors.
Beta Limitations: Beta may not fully capture risk; past volatility doesn’t always
predict future risk.
Easy2Siksha.com
Empirical Weakness: Studies show CAPM predictions often don’t match actual
returns.
Ignores Other Factors: Models like the Fama-French three-factor model include size
and value effects, which CAPM overlooks.
󷈷󷈸󷈹󷈺󷈻󷈼 Wrapping It Up
CAPM is like a compassit points you in the right direction by linking risk and return, but it
doesn’t guarantee you’ll reach your destination. Its features make it simple and widely
used, but its assumptions limit its accuracy in real-world markets.
SECTION-C
5. Dene investment. What are various investment objecves?
Ans: What is Investment?
Imagine you have some extra money. Instead of keeping it idle at home, you decide to use it
in a way that it grows over time. This act of putting your money into something with the
expectation of earning profit or income in the future is called investment.
In simple words:
󷷑󷷒󷷓󷷔 Investment means using your money today so that it can increase in value tomorrow.
For example:
Depositing money in a bank
Buying shares or mutual funds
Purchasing land or property
Investing in gold
All these are forms of investment because they are expected to give returns in the future.
Why Do People Invest?
Money kept idle loses its value over time due to inflation (rising prices). So, people invest to
grow their money, achieve financial goals, and secure their future.
Various Objectives of Investment
Easy2Siksha.com
Every person invests with some purpose. These purposes are called investment objectives.
Let’s understand the major ones in a simple and interesting way:
1. Safety of Capital
The first and most important objective is protecting your money.
People want to ensure that the money they invest does not get lost. That’s why many prefer
safe options like bank deposits or government bonds.
󷷑󷷒󷷓󷷔 Example: A retired person prefers fixed deposits because they are safe.
2. Regular Income
Some people invest to earn a steady flow of income.
This is especially important for people who depend on investments for their daily expenses.
󷷑󷷒󷷓󷷔 Example:
Interest from bank deposits
Dividends from shares
Rent from property
3. Capital Growth (Wealth Creation)
Another important objective is to increase the value of money over time.
Here, the focus is not just on regular income but on making the investment grow in value.
󷷑󷷒󷷓󷷔 Example:
Buying shares at ₹100 and selling them later at ₹200.
This is common among young investors who have time and can take risks.
4. Liquidity
Liquidity means how quickly you can convert your investment into cash.
People prefer investments that can be easily sold or withdrawn when needed.
Easy2Siksha.com
󷷑󷷒󷷓󷷔 Example:
Savings accounts (high liquidity)
Real estate (low liquidity)
5. Tax Saving
Some investments help in reducing tax liability.
People choose such options to save money on taxes while also earning returns.
󷷑󷷒󷷓󷷔 Example:
PPF (Public Provident Fund)
ELSS (Equity Linked Saving Scheme)
6. Protection Against Inflation
Inflation reduces the purchasing power of money.
So, investors choose options that grow faster than inflation.
󷷑󷷒󷷓󷷔 Example:
Investing in stocks or real estate can help beat inflation.
7. Risk Minimization
Every investment involves some level of risk.
Many investors aim to reduce risk by diversifying their investments.
󷷑󷷒󷷓󷷔 Example:
Instead of investing all money in shares, they divide it among shares, bonds, and gold.
8. Future Financial Security
People invest to secure their future needs like:
Retirement
Children’s education
Easy2Siksha.com
Marriage expenses
󷷑󷷒󷷓󷷔 Investment helps in planning for these long-term goals.
Conclusion
Investment is not just about earning moneyit is about planning your financial future
wisely.
Different people have different objectives:
Some want safety
Some want growth
Some want regular income
A good investor understands their goals and chooses investments accordingly.
6. Explain the concept of mutual funds. What is the dierence between porolio
management and mutual funds ?
Ans: 󷊆󷊇 What is a Mutual Fund?
A mutual fund is like a big basket of investments. Many investors contribute money, and a
professional fund manager invests that pool into stocks, bonds, or other securities.
How it works: You buy “units” of the fund, and your money is combined with others.
Who manages it: A fund manager decides where to invest.
Example: If you invest in an equity mutual fund, your money might be spread across
50 different companies’ shares.
Think of it like joining a buffetyou pay for your plate, and you get access to a wide variety
of dishes (investments) without having to cook yourself.
󷘹󷘴󷘵󷘶󷘷󷘸 Features of Mutual Funds
1. Diversification
o Your money is spread across many investments, reducing risk.
2. Professional Management
o Experts handle the buying and selling decisions.
3. Liquidity
o You can usually sell your units and get your money back quickly.
4. Accessibility
Easy2Siksha.com
o Even small investors can participate with modest amounts.
5. Transparency
o Funds regularly publish reports showing where your money is invested.
󽁗 What is Portfolio Management?
Portfolio management is more personalized. Instead of pooling money with others, you hire
a portfolio manager to design and manage your individual investment portfolio.
How it works: The manager studies your financial goals, risk appetite, and
preferences, then creates a tailored investment plan.
Who manages it: A portfolio manager or advisory firm works directly with you.
Example: If you want a mix of safe bonds and a few high-growth stocks, your
manager will build that exact portfolio for you.
Think of it like having a personal chefyou tell them your tastes, and they cook meals just
for you.
󷘹󷘴󷘵󷘶󷘷󷘸 Features of Portfolio Management
1. Customization
o Investments are tailored to your specific needs.
2. Direct Ownership
o You own the securities directly, unlike mutual funds where you own “units.”
3. Flexibility
o You can change your portfolio anytime based on your goals.
4. Expert Guidance
o Managers provide advice and adjust strategies as markets change.
5. Higher Costs
o Personalized service often comes with higher fees compared to mutual funds.

SECTION-D
7. Porolio management is a combinaon of the securies which will give maximum
return with minimum risk. Why/why not?
Ans: 󷊆󷊇 What is Portfolio Management?
Imagine you have some money to invest. Instead of putting all your money into one place
(like only shares or only gold), you spread it across different optionsshares, bonds, mutual
funds, etc. This combination is called a portfolio.
Easy2Siksha.com
Managing this combination wisely is known as portfolio management.
The main idea is simple:
󷷑󷷒󷷓󷷔 Don’t put all your eggs in one basket.
󷘹󷘴󷘵󷘶󷘷󷘸 The Ideal Goal: Maximum Return + Minimum Risk
In theory, portfolio management aims to:
Increase returns (profit)
Reduce risk (loss)
This idea comes from a famous concept in finance called diversification.
For example:
If one investment performs badly, another might perform well.
This balance helps protect your overall money.
So yes, portfolio management does try to achieve maximum return with minimum risk.
󽀼󽀽󽁀󽁁󽀾󽁂󽀿󽁃 But Heres the Reality
Now comes the important partthis idea is not 100% true in practical life.
Why?
Because of something very important:
󷷑󷷒󷷓󷷔 Risk and return are directly related.
This means:
Higher returns usually come with higher risk
Lower risk usually gives lower returns
So, it is not possible to completely eliminate risk and still get maximum returns.
󹵍󹵉󹵎󹵏󹵐 A Simple Example
Let’s say you have two options:
Easy2Siksha.com
1. Government bonds
o Very safe
o Low return
2. Stock market investments
o High return potential
o High risk
Now, if you want maximum return, you must take some risk.
If you want minimum risk, you must accept lower returns.
So, the goal of portfolio management is not perfection, but balance.
󼩏󼩐󼩑 What Portfolio Management Actually Does
Instead of achieving “maximum return with minimum risk,” portfolio management aims to:
Optimize returns for a given level of risk
Reduce unnecessary risk through diversification
Match investments with investor goals
This idea is explained by Modern Portfolio Theory (MPT), which says:
󷷑󷷒󷷓󷷔 You can create an “efficient portfolio” that gives the best possible return for a chosen
level of risknot zero risk.
󼩺󼩻 Key Factors That Affect Portfolio Management
1. Market conditions Prices keep changing
2. Economic factors Inflation, interest rates
3. Investor goals Short-term vs long-term
4. Risk tolerance Some people can handle risk, others cannot
Because of these factors, perfect balance is impossible, but smart balance is achievable.
󼫹󼫺 Final Answer: Why / Why Not?
Why (Yes):
Portfolio management helps reduce risk through diversification
It improves chances of better returns
It creates a balanced investment strategy
Easy2Siksha.com
󽆱 Why Not (Limitations):
Maximum return and minimum risk cannot be achieved together
Risk cannot be completely eliminated
Market uncertainty always exists
󷚚󷚜󷚛 Conclusion
So, the statement is partially true but not completely correct.
Portfolio management is not about creating a perfect combination with zero risk and
maximum profit. Instead, it is about finding the best possible balance between risk and
return.
8. What do you mean by porolio selecon problem ? What is its signicance ?
Ans: Portfolio Selection Problem: Concept and Significance
Let’s imagine you’ve saved some money and want to invest it. You could buy shares of a
tech company, put some into government bonds, or maybe invest in real estate. But here’s
the catch—you can’t put all your money into one option because that’s risky. At the same
time, you want to maximize your returns. So, how do you decide the right mix of
investments? This dilemma is what we call the portfolio selection problem.
󷊆󷊇 What is the Portfolio Selection Problem?
The portfolio selection problem refers to the challenge investors face when deciding how to
allocate their wealth across different assets (like stocks, bonds, mutual funds, or real estate)
in order to balance risk and return.
Risk: The chance that your investment may lose value.
Return: The profit or gain you expect from your investment.
The problem arises because investors want the highest possible return but with the lowest
possible risk. Since risk and return usually move together (higher returns often mean higher
risks), finding the “perfect balance” becomes tricky.
In simple terms, it’s like choosing a diet plan: you want tasty food (returns) but also healthy
options (low risk). The portfolio selection problem is about finding the right mix.
󷘹󷘴󷘵󷘶󷘷󷘸 Why Does This Problem Exist?
Easy2Siksha.com
1. Uncertainty in Markets
o No one can predict the future perfectly. Prices of stocks, bonds, and
commodities fluctuate.
2. Different Risk Levels
o Some assets are safe (like government bonds), while others are risky (like
start-up stocks).
3. Limited Resources
o Investors have limited money, so they must decide how to distribute it
wisely.
4. Diversification Needs
o Putting all money into one asset is dangerous. Spreading investments
reduces risk but complicates decision-making.
󽁗 Significance of the Portfolio Selection Problem
The portfolio selection problem is not just academicit has real-world importance for
investors, companies, and the economy. Let’s explore why it matters:
1. Helps Investors Balance Risk and Return
Investors don’t want to lose sleep worrying about their money.
By solving the portfolio selection problem, they can achieve a balance between
safety and profitability.
2. Foundation of Modern Investment Theory
The concept was formalized by Harry Markowitz in his Modern Portfolio Theory
