Provide and explain an alternative approach, other than the
discount growth model, that is often used to valuate stocks.
Critically discuss one limitation of this alternative approach
Answers:
Analysts often use multiples (financial ratios) to estimate stock
prices, such as EV (total firm value)/EBITDA, EV/Sales, P/E ratios,
etc.
Firstly, analysts estimate the average or median multiple value(s),
e.g., P/E ratio of comparable firms (or firms within an
industry/sector). This is called the P/E multiple. This multiple is
then multiplied by the expected earnings of the company to
estimate its stock price.
Problems with the market-multiple approach:
* It is often difficult to find or define comparable firms.
* Some multiples can be used for firms in any sector and across
the entire market, but some multiples can be used only for
specific sectors; e.g., internet firms by the later 1990s had
negative earnings and low revenues and book value.
* The average ratio of a multiple can have a wide range; e.g.,
the average P/E is 25, but the range could be from 8 to 70
what are the assumptions of CAPM?
CAPM Assumptions:
- Investors are rational, mean-variance optimizers.
- Their common planning horizon is a single period.
- Investors all use identical input lists, an assumption often termed
homogeneous expectations. Homogeneous expectations are consistent
with the assumption that all relevant information is publicly available. - All assets are publicly held and trade on public exchanges.
- Investors can borrow or lend at a common risk-free rate, and they can take
short positions on traded securities. - Investors pay no taxes or transaction costs
what are the unrealstic assumptions of CAPM?
Main unrealistic Assumptions that should be discussed:
- Investors pay no taxes or transaction costs
- investors can borrow and lend at a risk-free rate, and they can take short
positions on traded securities. - homogeneous expectations
What is securitisation and what are the downsides?
What is securitisation?
→ Pooling illiquid assets (e.g. mortgages) and repackaging them as securities sold to investors.
Two disadvantages:
1️⃣ Moral hazard — banks lower lending standards since risks are offloaded.
2️⃣ False diversification & opacity — tranches may seem safe but underlying assets are highly correlated and complex, leading to hidden risks.
What are the three forms of the Efficient Market Hypothesis (EMH). Briefly discuss and explain three tests that can be used to investigate the validity of the EMH (i.e., one test for each form of EMH).
3 Forms of EMH:
→ Weak: Prices reflect all past trading data.
→ Semi-strong: Prices reflect all public info (fundamentals + past prices).
→ Strong: Prices reflect all info, even insider info.
Tests:
→ Weak: Momentum/Reversal tests (short & long horizon returns).
→ Semi-strong: Market anomalies (e.g. small firm, P/E effects).
→ Strong: Insider trading profitability tests.
(c) Discuss and explain two types of cognitive bias investors may be subject to?
Two investor cognitive biases:
→ Overconfidence: Overestimate skills/forecasts → excessive trading & risk.
→ Extrapolation bias: Overweight recent trends → poor long-term judgment.
what are the tests for the three differnet forms of EMH?
weak form: Momentum (short term) → do prices keep going up/down after recent moves?
Reversal (long term) → do past winners become losers and vice versa?
✅ If these patterns exist → weak-form EMH is violated.
Semi strong: Market anomalies → e.g.
Small Firm Anomaly → small firms outperform
P/E Effect → low P/E stocks outperform
Book-to-Market → high book-to-market stocks outperform
strong: Insider trading studies → do insiders earn abnormal returns?
What is modified duration of a bond? Why it is important for
a bond holder?
Modified duration is a measure of a bond price sensitivity to changes in its yield to maturity. It is calculated by dividing the Macaulay’s duration of the bond by a factor of (1 + y/m) where y is the annual yield to maturity and mis the total number of coupon payments per period.
Why preferred stock gets priority over common stock upon liquidation?
Because they are higher ranked.
Preferred stocks are senior (i.e., higher ranking) to common stock, but
subordinate to bonds in terms of claim (or rights to their share of the assets of the company) and may have priority over common stock (ordinary shares) in the payment of dividends and upon liquidation
What is market liquidity, and why is it important for investors?
A:
Market liquidity is how easily an asset can be bought or sold quickly and at stable prices, without causing big price movements.
High liquidity = many buyers/sellers, fast transactions, stable prices
Low liquidity = few participants, harder to trade, more risk
Why it matters:
Low liquidity increases risk
You may struggle to exit a position or get stuck with worse prices
Especially important in volatile markets
If you know that the market is weak-form efficient would you use fundamental analysis?
Yes, since only historical information is reflected in the current share price, while future
expectations not yet absorbed by market.
What is cryptocurrency?
They are online ledgers and therefore money can be sent between individuals on a peer-topeer basis without the need to go through a financial institution. They have no physical association with any authority/country, have no physical representation, and have been argued to be an alternative currency
What is Efficient Frontier?
The efficient frontier is the set of optimal portfolios that offer the highest expected return for a
defined level of risk or the lowest risk for a given level of expected return. Portfolios that lie
below the efficient frontier are sub-optimal because they do not provide enough return for the
level of risk. Portfolios that cluster to the right of the efficient frontier are sub-optimal because they have a higher level of risk for the defined rate of return..
What is a correlation analysis? Does it change over time?
Correlation analysis evaluates how asset prices move in relation to one another. It’s crucial for diversification because:
A well-diversified portfolio considers each asset’s risk/return profile, economic sensitivity, and correlation with other assets.
Correlation is not fixed — it’s based on historical data and can change over time, especially during market crises.
Assuming stable correlations can lead to underestimating risk and overestimating diversification.
Example: During the Global Financial Crisis or Eurozone crisis, correlations between assets often spiked unexpectedly.
Do you believe that media/news affect asset prices? Which
theories support your position?
Answer can be linked to EMH, or to Behavioural Finance.
What are the examples of alternative investments?
Anything that is not included in main equity/debt investments, such as commodities, real
estate, gold, cryptocurrencies etc
What are alternative investments and what are the main risks compared to traditional ones?
Alternatives = non-traditional assets (e.g., real estate, hedge funds, private equity, crypto, gold).
Risks:
Illiquidity
Difficult valuation
Higher fees
Complex/negative tax treatment
Lack of regulation
Fraud and forgery risk
Due diligence burden
Less transparency and market efficiency than stocks/bonds.
Q: What are the main functions of financial intermediaries?
Maturity transformation (short-term deposits → long-term loans)
Risk diversification (pooling investments)
Liquidity provision (easy access to funds)
Credit allocation (screening borrowers)
Reducing information asymmetry
Economies of scale & expert investment management
Transporting funds through time (e.g., saving/investing or borrowing)
If the market is weak-form efficient, should you use technical analysis? Why?
No. Weak-form efficiency assumes all past price data is already reflected in stock prices, making technical analysis ineffective. Price movements are random, so past trends don’t predict future performance.
Q: How would the portfolios of a highly risk-averse vs. less risk-averse investor differ?
Highly risk-averse investor: holds safer assets (e.g., bonds, cash, low-volatility stocks).
Less risk-averse investor: allocates more to risky assets (e.g., equities, alternatives) for higher potential return.
Risk aversion affects the balance between risk and return in portfolio construction.
What is the difference between systematic and non-systematic risk?
Systematic risk: Market-wide, non-diversifiable (e.g., interest rates, inflation, recessions).
Non-systematic risk: Firm-specific, diversifiable (e.g., bad management, product recalls).
Diversifying across assets reduces non-systematic risk, but not systematic risk.
What are cryptocurrencies, and why have they become popular?
Definition: Digital assets enabling peer-to-peer transactions via a decentralised ledger (blockchain).
Decentralised: No single authority (unlike central banks).
Popularity drivers:
Diversification (low correlation with traditional assets)
High volatility = potential for large gains
Forced scarcity (e.g., Bitcoin supply cap)
Low transaction costs (especially for global transfers)
Anonymity (pseudo/fully anonymous coins like Monero)
Use in DeFi (non-bank lending, staking, etc.)
Global access (useful in underbanked regions)
What are the three forms of the Efficient Market Hypothesis?
Weak-form: Prices reflect all past trading data (e.g. price trends, volumes).
Semi-strong form: Prices reflect all publicly available info, including past data, news, reports.
Strong-form: Prices reflect all public and private (insider) information.
How are hedge funds different from mutual funds?
Investor access: Hedge funds = for wealthy or institutional clients; mutual funds = public access.
Strategies: Hedge funds use short selling, leverage, derivatives; mutual funds follow safer, regulated strategies.
Regulation: Mutual funds are strictly regulated & transparent; hedge funds are less regulated and secretive.
