1 Exam Theory Questions
1.1 Discuss the attributes relevant for evaluating an investment avenue.
ANSWER:
Five key attributes relevant for evaluating the investment
avenue are:
Rate of return
Risk
Marketability
Tax Shelter
Convenience
Return is computed on the principal amount invested for
duration. The rate of return takes into account the
current yield and the capital gains/losses. The current
yield is the short term returns on the actual
investment, in the form of interest or
dividends. Current yield has an impact on the overall
return as it is received at different time periods. The
overall capital appreciation is the increase in the
principal amount invested and is received only after
termination of the investment tenure.
Annual Income (End Price - Beginning Price) Rate of Return = ------------------ + ----------------------------- Beginning Price Beginning Price = Current Yield + Capital Appreciation
Hint: Give examples of bond and gold to contrast.
- Risk
- Is defined as the variability of the rate of return. An instrument that has fixed return and guaranteed, has less risk. For example: Govt. NSCs. The variance of return in possible in investments like Mutual funds and equities, where the variance is huge, is considered a high risk investment. Variance This is the mean of the squares of deviations of individual returns around their average value. Standard Deviation This is the square root of variance. Beta This reflects how volatile is the return from an investment in response to market swings.
- Marketability/Liquidity
- An investment is highly marketable or liquid if: (a) it can be transacted quickly (b) the transaction cost is low (c) the price change between two successive transactions is negligible
- Tax Shelter
- (a) Initial tax benefit (b) Continuing tax benefit (c) Terminating tax benefit
- Convenience
- refers to the ease with which the investment can be made and looked after. For example, can the investment be made readily? Can the investment be looked after easily? Savings bank account and chasing real estate property are two different extremes.
1.2 What qualities are required for successful investing? [Jan 2009]
ANSWER:
Contrary Thinking
Patience
Composure
Flexibility and openness
Decisiveness
1.3 Describe the following types of insurance policies: endowment assurance, money back plan, whole life assurance, term assurance, and deferred annuity.
ANSWER:
- Endowment Assurance (Non-Participating and Participating)
- a. Non-Participating endowment policy assures a guaranteed amount at the maturity date of the policy in exchange for a single premium. b. Participating Endowment Policy enhances the initial sum assured with payment of bonuses to policyholder. Eg. LIC Jeevan Anand, Jeevan Mitra
- Money Back Plan
- Savings cum protection plan as it provides lumpsum at periodic intervals. Eg. LIC Jeevan Surabhi, Jeevan Bharati
- Whole Life Assurance
- provides a benefit on the death of the policyholder whenever that might occur. Eg. LIC Jeevan Anand, Jeevan Tarang
- Term Assurance
- A pure protection policy that provides benefit on the death of the policyholder within the specified term stated in the policy. Eg. LIC Anmol Jeevan
- Deferred Annuity
- Pension scheme Eg. LIC Jeevan Nidhi
1.4 Discuss the major changes that have occurred in the equity market in India since 1992.
ANSWER:
In 1990, there was a major capital market scam where bankers and
brokers were involved. With this, many investors left the
market. Later there was a securities scam in 1991-92 which revealed
the inefficiencies and inadequacies of the Indian financial system
and called for reforms in the Indian Equity Market.
1994 - National Stock Exchange of India (NSE) and OCTEI (Over the
Counter Exchange of India) were established.
1995-96 - Securities Contracts (Regulation) Act was ammended to
introduce options trading.
1995-96 - NSCC and NDSL were setup for demutualized trading,
clearing and settlement.
In February 2000, permission was given for internet trading and
from June, 2000, futures trading started.
From 1st July 2001, ‘Badla' was discontinued and there was
introduction of rolling settlement in all scrips, after Ketan
Parekh scam.
Till 2001, India was the only sophisticated market having account
period settlement alongside the derivatives products. From middle
of 2001, uniform rolling settlement and same settlement cycles were
prescribed creating a true spot market.
The VaR based margining system was introduced in mid 2001
India is one of the few countries to have started the screen based
trading of government securities in January 2003.
In June 2003 the interest rate futures contracts on the screen
based trading platform were introduced.
1.5 Discuss the key features of the G-sec market in India.
ANSWER:
G-Secs or Government of India dated Securities are Rs.100
face-value units / debt paper issued by Government of India
in lieu of their borrowing from the market. These can be referred
to as certificates issued by Government of India through the
Reserve Bank acknowledging receipt of money in the form of debt,
bearing a fixed interest rate (or otherwise) with interests payable
semi-annually or otherwise and principal as per schedule, normally
on due date on redemption.
Key features of G-Sec are:
Issue of G-Secs is regulated by RBI under the Public Debt
Act. G-Secs are issued through an auction mechanism.
Participants Banks are the largest holders of G-Secs. About
one-third of the net demand and time liabilities of the banks
are invested in G-Secs maintly to meet the statutory liquidity
requirements and partly for investment purposes. Other
participants include insurance companies, provident funds,
mutual funds, primary and satellite dealers and trusts.
SGL Account facility is provided by RBI to large banks and
financial institutions so that they can hold their G-secs and
treasury bills in electronic book entry form.
Primary dealers are important intermediaries in the G-sec
market. They serve as underwriters in debt market, act as market
makers in secondary debt market, and enable investors to access
the SGL account.
Secondary market for G-secs As soon as G-secs are issued, they
are deemed to be listed and eligible for trading. The NSE has a
Wholesale Debt Market (WDM) which is a fully automated screen
based trading system.
Transactions in G-secs are settled through the delivery versus
payment (DVP) mode.
1.6 Why do companies manipulate the bottom line? What devices are used to do so?
ANSWER:
To project an image that the company is a low-risk company
To enhance managerial compensation, if the same is linked in
some way to reported earnings
To promote a perception that the management of the firm is
competent.
To communicate more meaningfully about the long-term
prospects of the firm.
(### ADD TEXT: WWW)
1.7 Discuss the problems and issues faced in financial statement analysis.
ANSWER:
Heuristical in nature - the financial analysis does not result in
concrete financial position of the firm. It only gives clues
for further study or decision making. There are no established
rules that directly give the results about the financial
health of the firm.
Relies on benchmarks - Financial analysis is based on
comparison of firms financial ratios against the industry
average ratios. This comparison for a multi-industry
corporation is not only difficult, but at times
impossible. Because, there might be no firm of similar
industry mix to get a industry standard benchmark.
Easy Window dressing - It is easy to manipulate and project
balance sheet to produce favorable financial ratios. To
overcome this, the auditor should do a deep dive into the
parameters under study. For example: A firm with a very
comfortable liquidity position and a high turnover of
inventories.
Price Level changes - In India the financial accounting
does not take into account the price level changes that have
impact on financial statements.
Variations in Accounting Policies - Business firms have
some freedom in accounting treatment of items like
depreciation, valuation of stocks, research and development
expenses, foreign exchange transactions, installment sales,
etc. Due to diversity of policies found in practice,
comparative financial statement analysis may be vitiated.
Subjectivity in Interpretation - It is difficult to judge
whether certain ratio is good or bad. A high current ratio,
for example, may indicate a strong liquidity position
(something good) or excessive inventories (something bad). But
is becomes difficult when a firm has good as well as bad
financial ratios.
Correlations among ratios - Financial ratios of a firm show
a high degree of correlation as most ratios share either
numerator or denominator.
1.8 Explain the single index model proposed by William Sharpe.
ANSWER:
William Sharpe model was proposed to overcome the limitation of
Markowitz model. In Markowitz model, the number of computations of
covariance increases dramatically with increase in number of stocks
under consideration. If there are n securities, Markowitz model
requires n expected returns, n variance terms, and n(n-1)/2
covariance terms. For example, if an analyst is considering 100
securities, Markowitz model requires 100 expected returns, 100
variance terms and 4950 covariance terms.
To simplify analysis, the single-index model assumes that there is
only 1 macroeconomic factor that causes the systematic risk
affecting all stock returns. This factor can be represented by
the rate of return on a market index, such as the S&P
According to this model, the return of any stock can be
decomposed into the expected excess return of the individual stock
due to firm-specific factors, commonly denoted by its alpha
coefficient (α), the return due to macroeconomic events that
affect the market, and the unexpected microeconomic events that
affect only the firm.
http://thismatter.com/money/investments/single-index-model.htm
Rit = ai + bi RMt +eit
Rit = Return on security i in period t
RMt = return on the market index in period t
ai = constant return
bi = measure of the sensitivity of the security i return to
the return on the market index (popularly called beta)
eit = error term
Assumptions in the single index model
The error term (eit) has an expected value of zero and a
finite variance
The error term is not correlated with the return on the market portfolio
Cov(eit, RMt) = 0
Securities are related only through their common response to
the return on the market index. This implies that the error
term for security i is not correlated with the error term for
any other security:
Cov(eit, ejt) = 0
Single index model has computational advantages of magnitude
defined below:
To compute Markowitz model you need n(n+3)/2 computations;
Single index model you only need 3n+2 estimates (100 sec, 302
inputs).
1.9 Discuss the procedure commonly used in practice to test the CAPM.
ANSWER: READ Page 256
The Capital Asset Pricing Model (CAPM) is an economic model for
valuing stocks, securities, derivatives and/or assets by relating
risk and expected return. CAPM is based on the idea that investors
demand additional expected return (called the risk premium) if they
are asked to accept additional risk.
The CAPM model says that this expected return that these investors
would demand is equal to the rate on a risk-free security plus a
risk premium. If the expected return does not meet/beat the
required return, the investors will refuse to invest and the
investment should not be undertaken.
The CAPM formula is:
Expected Security Return = Riskless Return + Beta x (Expected Market
Risk Premium)
A consequence of CAPM-thinking is that it implies that investing in
individual stocks is pointless, because one can duplicate the
reward and risk characteristics of any security just by using the
right mix of cash with the appropriate asset class. This is why
die-hard followers of CAPM avoid stocks, and instead build
portfolios merely out of low-cost index funds.
The Capital Asset Pricing Model is a ceteris paribus model. It is
only valid within a special set of assumptions. These are:
Investors are risk averse individuals who maximize the expected
utility of their end of period wealth.
Implication: The model is a one period model.
Investors have homogenous expectations (beliefs) about asset
returns.
Implication: all investors perceive identical opportunity
sets. This is, everyone have the same information at the same
time.
Asset returns are distributed by the normal distribution.
There exists a risk free asset and investors may borrow or lend
unlimited amounts of this asset at a constant rate: the risk free rate.
There is a definite number of assets and their quantities are
fixed within the one period world.
All assets are perfectly divisible and priced in a perfectly competitive marked.
Implication: e.g. human capital is non-existing (it is not
divisible and it can’t be owned as an asset).
Asset markets are frictionless and information is costless and
simultaneously available to all investors.
Implication: the borrowing rate equals the lending rate.
There are no market imperfections such as taxes, regulations, or
restrictions on short selling.
Commonly followed procedure involves three basic steps:
Set up the sample data
Compute:
Rit = Returns on n securities over the t period of time
RMt = Returns on a market portfolio proxy over the t month period
Rft = Return on risk free investment over t month period
Estimate the Security Characteristics Line (Beta)
Rit = ai + bi RMt + eit
Rit - Rft = ai + bi (RMt-Rft) + eit
Estimate the Security Market Line
With the Beta estimates of various securities, you can estimate the SML.
Ri = Y0 + Y1 bi + ei
If CAPM holds
The relationship should be linear.
Y0, the intercept, should not be significantly different
from risk free return, Rf
Y1, the slope coefficient should not be significantly
different from RM-Rf
No other factors, such as company size or total variance,
should affect Ri
The model should explain the significant portion of
variation in returns among securities.
1.10 Discuss the following approaches to beta estimation:
(a) betas based on fundamental information and
(b) betas based on accounting information.
ANSWER:
Factors employed for predicting betas based on fundamental
information are:
Industry Affiliation: Beta varies across industries.
Corporate Growth: Growth and Beta are correlated.
Earnings Variability: Greater the variability of
earnings over time, greater beta.
Financial Leverage: Greater the financial leverage,
higher the beta is likely to be.
Size: Larger the size of a company, smaller the beta.
One can estimate the beta of a company using the accounting
information rather than the traded prices. This involves
regressing the changes in company earnings (on a quarterly or
annually) against changes in the earnings for the market (the
aggregate earnings of all the companies included in the market
index which is used as the proxy for the market).
Limitations of this approach:
Accounting earnings are generally smoothed out, relative to
the value of the company.
Accounting earnings are influenced by non-operating factors
like extraordinary gains or losses and changes in
accounting policy with respect to depreciation, inventory
valuation, and so on.
Compared to stock prices which are observed on a daily
basis, accounting earnings are measured at less frequent
intervals. This means that regression analysis using accounting
data will have fewer observations and have lesser power.
1.11 Discuss the Arbitrage Pricing Theory.
ANSWER:
http://www.money-zine.com/Investing/Stocks/Arbitrage-Pricing-Theory-or-APT/
APT model was first described by Steven Ross. The APT assumes
that each stock's (or asset's) return to the investor
is influenced by several independent factors.
The APT Formula
Furthermore, Ross stated that the return on a stock must follow a
very simple relationship that is described by the following APT
formula:
Expected Return = rf + b1 x (factor 1) + b2 x (factor 2)… + bn x (factor n)
Where:
rf = The risk free interest rate is the interest rate the
investor would expect to receive from a risk free
investment. Typically, US Treasury Bills are used for
US dollars and German Government bills are used for
the Euro
b = the sensitivity of the stock to each factor
factor = the risk premium associated with each factor
The APT model also states that the risk premium of a stock
depends on two factors:
The risk premiums associated with each of the factors described
above
The stock's own sensitivity to each of the factors - similar
to the beta concept
Risk Premium = r - rf = b1 x (r factor(1) - rf) + b2 x (r factor(2) - rf… + bn x (r factor(n) - rf
If the expected risk premium on a stock were lower than the
calculated risk premium using the formula above, then investors
would sell the stock. If the risk premium were higher than the
calculated value, then investors would buy the stock until both
sides of the equation were in balance. Arbitrage is term used to
describe how investors could go about getting this formula, or
equation, back into balance.
Factors Used in the Arbitrage Pricing Theory
It's one thing to describe the APT theory in terms of simple
formulas, but it's another matter entirely to identify the
factors used in this theory. That's because the theory itself
does not tell the investor what those factors are for a
particular stock or asset - and for very good reason. In
practice, and in theory, one stock might be more sensitive to one
factor than another. For example, the price of a share of
ExxonMobil might be very sensitive to the price of crude oil,
while a share of Colgate Palmolive might be relatively
insensitive to the price of oil.
In fact, the Arbitrage Pricing Theory leaves it up to the
investor, or analyst, to identify each of the factors for a
particular stock. So the real challenge for the investor is to
identify three things:
Each of the factors affecting a particular stock
The expected returns for each of these factors
The sensitivity of the stock to each of these factors
Identifying and quantifying each of these factors is no trivial
matter and is one of the reasons that the Capital Asset Pricing
Model remains the dominant theory to describe the relationship
between a stock's risk and return.
Keeping in mind that the number and sensitivities of a stock to
each of these factors is likely to change over time, Ross and
others identified the following macro-economic factors they felt
played a significant role in explaining the return on a stock:
Inflation
GNP or Gross National Product
Investor Confidence
Shifts in the Yield Curve
With that as guidance, the rest of the work is left to the stock
analyst.
APT versus the Capital Asset Pricing Model
As mentioned, the APT and the Capital Asset Pricing Model (CAPM)
are the two most influential theories on stock and asset pricing
today. The APT model is different from the CAPM in that it is
far less restrictive in its assumptions. APT allows the
individual investor to develop their model that explains the
expected return for a particular asset.
Intuitively, the APT makes a lot of sense because it removes the
CAPM restrictions and basically states "the expected return on an
asset is a function of many factors and the sensitivity of the
stock to these factors." As these factors move, so does the
expected return on the stock - and therefore its value to the
investor.
In the CAPM theory, the expected return on a stock can be
described by the movement of that stock relative to the rest of
the stock market. The CAPM theory is really just a simplified
version of the APT, whereby the only factor considered is the
risk of a particular stock relative to the rest of the stock
market - as described by the stock's beta.
From a practical standpoint, CAPM remains the dominant pricing
model used today. When compared to the Arbitrage Pricing Theory,
the Capital Asset pricing model is both elegant and relatively
simple to calculate versus what's required by the APT formula.
1.12 Describe the common misconceptions about the Efficient Market Hypothesis. How would you dispel them?
ANSWER:
| Misconception | Answer |
|---|---|
| <30> | <30> |
| The efficient market hypothesis implies that the market has perfect forecasting capabilities. | The EMH merely implies that prices impound all available information. This does not mean taht the market possesses perfect forecasting capabilities. |
| As prices tend to fluctuate, they would not reflect fair value. | Unless prices fluctuate, they would not reflect fair value. Since the future is uncertain, the market continually surprised. As prices reflect these surprises they fluctuate. |
| Inability of institutional portfolio managers to achieve superior investment performane implies that they lack competence. | In an efficient market, it is ordinarily not possible to achieve superior investment perf. Market efficiency exists because portfolio mgrs are doing their job well in a competitive setting. |
| The random movement of stock prices suggests that the stock market is irrational. | Randomness and irrationality are two different matters. If investors are rational and competitive, price changes are bound to be random. |
1.13 What steps are involved in an 'event study'? What steps are involved in a 'portfolio study'?
ANSWER:
An event examines the market reactions to and the excess market
returns around a specific information event like acquisition
announcement or stock split.
Involved in event study:
Identify the event to the studied and pinpoint the date on
which the event was announced.
Event studies presume that the timing ofthe event can be
specified with a fair degree of precision. Because, financial
markets react to the announcement of an event, rather than the
event itself, event studies focus on announcement date of the
event.
Collect returns data around the announcement date. This is the
retuns window (number of dates before and after).
Calculate the excess returns, by period, around the
announcement date for each firm in the sample.
The excess return is calculated by making adjustment for
market performance and risk. For example, if the CAPM is
employed to control for risk the excess return is calculated
as:
ERjt = Rjt - Betaj x Rmt
where
E Rjt = excess return on firm j for period t
Betaj = beta of firm j
Rmt = returns on market for period t
Compute the average and the standard error of excess
returns across all firms.
Assess whether the excess returns around the announcement
date are different from zero.
In a portfolio study, a portfolio of stocks having the observable
characteristic (low price earnings ratio or whatever) is created
and tracked over time to see whether it earns superior
risk-adjusted returns.
Define study the variable (characteristic) on which firms
will be classified
Classify firms into portfolios based upon the magnitude of
the variable
Compute the returns for each portfolio
Calculate the excess returns on each portfolio
Assess whether the average excess returns are different
across the portfolios
1.14 Discuss the alternative paradigm of 'noise trading and limited arbitrage' as articulated by Scheifer, Summers, and others.
ANSWER:
Noise Trading:
Many investors trade on pseudo-signals, or noise, and not on
fundamentals. As long as these investors trade randomly, their
trades cancel out and are likely to have perceptible impact on
demand. True, this happens to some extent because the market is
thronged by noise traders who employ different models and, hence,
cancel each other out. However, a good portion of noise traders
employ similar strategies, as they suffer from similar judgmental
bias while processing information. For example:
a. They tend to be overconfident and hence assume more risk
b. They tend to extrapolate past time series and hence chase
trends
c. They tend to put lesser weight on base rates and more weight
on the information and hence overreact to news
d. They follow market gurus and forecasts and act in similar
fashion.
Limits of Arbitrage:
One can expect the irrationality of noise traders to be
countered by the rationality of arbitrageurs as the latter are
supposed to be guided by fundamentals and immune to
sentiments. However, arbitrage in the real world is limited by
two types of risk. The first risk, is fundamental. Buying
undervalued securities tends to be risky because the market may
fall further and inflict losses. The fear of such a loss may
restrain arbitrageurs from taking large enough long positions
that will push price to fully confirm to fundamentals.
The second is resale price risk and it arises mainly from the
fact that arbitrageurs have infinite horizons for two reasons:
i) arbitrageurs usually borrow money or securities to implement
their trades and therefore have to pay fees periodically. So,
they can ill-afford to keep an open position for long horizon.
ii) Portfolio managers are evaluated every few months. This
limits their horizon to arbitrage.
1.15 Discuss the investment implications of the Efficient Market Hypothesis.
ANSWER:
Random walk theory is against the technical analysis and
both parties debate over it. There is much evidence to the
nature of randomness in stock price behaviour.
Routine and conventional fundamental analysis is of not
much help in identifying profitable courses of action, more
so when you are looking at actively traded
securities. Market is imperfect.
The key levers for earning superior rate of return are:
early action on any new development
Sensitivity to market imperfections, and
innovative mode of analysis
Use of original, unconventional, and innovative
modes of analysis
Access to inside information and its sensible
interpretation
An independent judgment that is not affected my
market psychology
1.16 Discuss the risks that debt instruments are subject to.
ANSWER:
- Interest Rate Risk
- Interest rates tend to vary over time and affect bond prices. They are inversely related. Also referred to as market risk. Interest rate risk affects the value of bonds more directly than stocks, and it is a major risk to all bondholders. As interest rates rise, bond prices fall and vice versa. The rationale is that as interest rates increase, the opportunity cost of holding a bond decreases since investors are able to realize greater yields by switching to other investments that reflect the higher interest rate. For example, a 5% bond is worth more if interest rates decrease since the bondholder receives a fixed rate of return relative to the market, which is offering a lower rate of return as a result of the decrease in rates.
- Inflation Risk
- As interest rates are defined in nominal terms, the real return decreases and makes it less attractive to the buyers. Inflation is the artificial expansion of the quantity of money so that too much money is used in exchange for goods and services. To consumers, inflation shows up inteh form of higher prices. Inflation risk is also referred to as purchasing parity risk. This term just means that money doesn't buy as much as it used to. Since financial contracts are stated in nominal term, the real interest rate should be adjusted for the expected inflation. According to Fisher Effect, the following relationship holds between nominal rate r, real rate a, and the expected inflation rate alpha. r = 1 + alpha + a x alpha When the inflation is higher than expected, the borrower gains at the exposure of the lender and vice-versa.
- Real Interest Rate Risk
- Shifts in supply and/or demand for funds change the real interest rate. The company giving debt might itself earn less on (leasing, selling) assets and may be paying more debt interest due to real interest rate.
- Default Risk
- Borrower may not pay interest and/or principal on time. Also, referred to as Credit Risk is normally gauged by the rating assigned by debt instrument by an independent credit rating agency (like CRISIL, ICRA or CARE). Other things being equal, bonds which carry a higher default risk (lower credit rating) trade at higher yield to maturity.
- Call Risk
- The issuer has an option to call intermittently before maturity period. At that point the investor is subject to call risk as he cannot reinvest the money in any other comparable instrument.
Many bonds include a call feature that allows the issuer to redeem or call all or part of the issue before the maturity date. The issuer usually retains this right in order to have flexibility to refinance the bond in the future if the market interest rate drops below the coupon rate. This implies three risks from the investor:
The cash flow pattern becomes uncertain,
The investor becomes exposed to reinvestment risk
because the issuer will call the bond when interest
rates drop, and
The capital appreciation potential of a bond will be
reduced, because the price of a callable bond may not
rise much above the price at which the issuer will
call the bond.
- Liquidity Risk
- All other debt instruments, other than Govt. sponsored to not have much liquidity in market.
1.17 What are the important properties of duration?
ANSWER:
Duration of a bond is the weighted average maturity of its
cash flow stream, where the weights are proportional to the
present value of cash flows.
Duration is the key concept in bond analysis for two reasons:
It measures the interest rate sensitivity of a bond
It is a useful tool for immunising against interest rate
risk.
Properties of duration:
Duration of a zero-coupon bond is same as its maturity
For a given maturity, a bond′ s duration is higher when its
coupon rate is lower
For a given coupon rate, a bond`s duration generally
increases with maturity
Other things being equal, the duration of a coupon bond
varies inversely with the yield to maturity.
The duration of a level of perpetuity is:
(1 + yield)/yield
The duration of a level annuity approximately is:
(1 + yield) Number of payments --------------- - ----------------------------------- yield (1 + yield)^{number of payments} - 1
The duration of a coupon bond approximately is:
1+y (1+y) + T(c-y) ----- - ----------------------------------- y c [(1+y)T-1] + y
1.18 What is debt rating? What are the functions of debt ratings (or debt rating firms)?
ANSWER:
Debt ratings are the grading system given to bonds to assess
their investment qualities, like timely payment of interest,
principal. Higher the rating, higher the chances of investor
getting back his money. This can also be considered,
peace-of-mind indicator for the investor.
Functions of Debt Rating:
Provide superior information
Offer low-cost information
Serve as a basis for a proper risk-return trade-off
Impose healthy discipline on corporate borrowers
? Lend greater credence to financial and other representations
Facilitate the formulation of public policy guidelines on
institutional investment.

Volume
Sentiment indicators

Mutual fund liquidity
If the mutual fund liquidity is low, it means that mutual funds
are bullish. So contrarians (who think crowd is wrong) argue that
the market is at, or near, a peak and hence likely to
decline. Thus, low mutual fund liquidity is considered as bearish
indicator.

1.25 Evaluate technical analysis.
ANSWER:
Advocates of Technical Analysis:
Under influence of crowd psychology, trends persist for quite
some time.
Shifts in demand and supply are gradual rather than
instantaneous.
Fundamental information about a company is absorbed and
assimilated by the market over a period of time.
Charts provide a picture of what has happened in the past and
hence give a picture of volatility that can be expected from the
stock.
Detractors of Technical Analysis:
Most technical analysts are not able to offer convincing
explanations for the tools employed by them.
Empirical evidence in support of the random-walk hypothesis
casts its shadow over the usefulness of technical analysis
By the same time an uptrend or downtrend may have been signaled
by technical analysis, it may already have taken place
Technical analysis is a self-defeating proposition. As more and
more people use it, the value of such analysis tends to
decline.
The numerous claims that have been made for different chart
patterns are simply untested assertions.
There is a great deal of ambiguity in the identification of
configurations as well as trend lines and channels on the
charts.

1.29 Explain the principal vectors of an active portfolio strategy.
ANSWER:
An active portfolio strategy is followed by most investment
professionals and aggressive investors who strive to earn superior
returns, after adjustment for risk.
Four principal vectors of an active strategy are:
Market timing
Sector rotation
Security selection
Use of a specialized concept
is based on an explicit and implicit forecast
of general market movements. The advocates of market timing
employ a variety of tools like business cycle analysis, moving
average analysis, advance-decline analysis, and econometric models.
A careful study on market timing argues that the investment
manager must forecast the market correctly 75 percent of the
time just to break-even, after taking into account the cost of
errors and the costs of transactions.
This concept applies to stocks as well as
bonds. Tilt the portfolio towards growth industries and sectors,
compared to market selection.
With respect to bonds, sector rotation implies a shift in the
composition of bond portfolio in terms of quality, coupon rate,
term of maturity, and so on. If you anticipate rise in interest
rates, you may shift from long term bonds to medium or short
term. Remember that long-term bonds are more sensitive to
interest rate variation compared to a short-term bond.
Most commonly used vector in active
portfolio strategy is the search under-priced security. If you
resort to active stock selection, you may employ fundamental
and/or technical analysis to identify stocks which seem to
promise superior returns and concentrate the stock component of
your portfolio on them.
like growth stocks,
neglected or 'out of favor' stocks, asset-rich stocks,
technology stocks, cyclical stocks.
