Equity Portfolio Management Flashcards
What is semiactive equity management?
Semiactive equity management (a.k.a. enhanced indexing or risk-controlled active management) attempts to earn a higher return than the benchmark while minimizing the risk of deviating from the benchmark.
What is the information ratio?
The information ratio combines expected active return and tracking risk into one risk-adjusted return measure. It is the expected active return divided by the tracking risk, so it shows the manager’s active return per unit of tracking risk (a.k.a. tracking error).
Rank (lowest to highest) the equity investment approaches by their information ratio, historically.

Describe a price-weighted index.
A price-weighted index is simply an arithmetic average of the prices of the securities included in the index. Computationally, a price-weighted index adds together the market price of each stock in the index and then divides this total by the number of stocks in the index. The divisor of a price-weighted index is adjusted for stock splits and changes in the composition of the index, so the total value of the index is unaffected by the change.
Describe a market capitalization-weighted index (value weighted).
A market capitalization-weighted index (value index) is calculated by summing the total market value (current stock price time the number of share outstanding) of all the stocks in the index.The value-weighted index assumes the investor holds each company in the index according to its relative weight in the index.
Describe a equal-weighted index.
In an equal-weighted index, all stock returns are given the same weight (i.e., the index is computes as if an investor maintains an equal dollar investment in each stock in the index). These indices must be periodically rebalanced to maintain equal representation of the component stocks.
What are the biases in a price-weighted index?
- Higher priced stocks will have a greater impact on the index’s value than lower priced stocks.
- The price of a stock is somewhat arbitrary and changes through time as a firm splits its stock, repurchases stock, or issues stock dividends. As a stock’s price changes through time, so does its representation in the index.
- The price-weighted index assumes the investor purchases one share (or the same number of shares) of each stock represented in the index, which is rarely followed by any investor in practice.
What are the biases in a value-weighted index and the free float-adjusted market capitalization index?
- Firms with greater market capitalization have a greater impact on the index than firms with lower market capitalization. This means that these indices are biased toward large firms that may be mature/or overvalued.
- These indices my be less diversified if they are over-represented by large-cap firms.
- Some institutional investors may not be able to mimic a value-weighted index if they are subject to maximum holdings and the index holds concentrated positions.
What are the biases of the equal-weighted index?
- The equal weighted index is biased towards small-cap companies because they will have the same weight as large cap firms even though they have less liquidity. Many equal-weighted indices contain more small firms than large firms.
- The required rebalancing of this index creates high transaction costs.
- The emphasis on small-cap stocks means that index investors may not be able to find liquidity in many of the index issues.

When may equity passive strategies be preferable?
Investor is/has
- Taxable.
- An information disadvantage in global markets.
- Investing in informationally efficient large-cap markets.
- Wants to avoid the high transactions costs in small-cap markets.
What are the differences between mutual funds and ETFs?
- Mutual funds trade once a day, ETFs trade through out the day.
- ETFs do not have to maintain recordkeeping for shareholders, whereas mutual funds do.
- Index mutual funds usually pay lower license fees to index providers, relative to the fees that ETFs pay.
- ETFs are generally more tax effcient.
- The cost of holding ETFs are lower.
Compared to ETFs, what are the two disadvantages of equity futures?
- Futures contracts have a finite life and must be periodically rolled over into a new contract.
- Using basket trades and futures contracts in combination for risk management can be problematic because a basket may not be shorted if one of the components violates the uptick rule.
Describe Optimization as an approach to constructing an indexed portfolio.
Optimization uses a factor model to match the factor exposures of the index. It accounts for the covariances between the risk factors.
What are possible problems with optimization in index construction.
The risk sensitivities may change through time. This may provide misleading results and lead to frequent rebalancing.
When is each approach to constrcting indexed portfolios preferable?
- Full replication is more appropriate for small indices when the index stocks are liquid and when the manager has more funds.
- Stratified sampling is more appropriate when the number of stocks in the index is large and/or the stocks are illiquid.
- Optimization leads to lower tracking risk than stratified sampling.
What are the three main categories of investment style and their characteristics?
Value investor - focuses on stocks with low price multiples (e.g., P/E ratio, P/B ratio)
Growth investor - favors stocks with high past and future earnings growth.
Market-oriented investor - Cannot be easily classified as value or growth.
What are the two techniques for identifying investment styles?
Returns-based style analysis - The returns on a manager’s fund are regressed against the returns for various security indices (e.g., large-cap value stocks, small-cap value stocks). The regression coefficients are constrained to be nonnegative and to sum to one.
Holding-based style analysis - Evaluates portfolio characteristics using the following attributes: value or growth, expected earnings growth, earnings volatility, and industry representation.
What are the advantages of returns-based style analysis?
Advantages: Low cost, quick, and consistent method of characterizing an entire portfolio.
Disadvantages: The regression may be misspecified, and it may be slow to detect style changes.
What are the advantages of holdings-based style analysis?
Advantages: It can characterize individual securities, and detect style changes quickly.
Disadvantages: It subjectively classifies securities, requires more data, and is not consistent with how most managers invest.
