Chapter 17 - Equity Portfolio Management Strategies
Questions to be answered:
• What are the two generic equity portfolio management styles?

• How does the goal of a passive equity portfolio manager differ from the goal of an active manager?
• What is a portfolio’s tracking error and how is it useful in the construction of a passive equity investment?
Chapter 17 - Equity Portfolio Management Strategies
• What is the difference between an index mutual fund and an exchange-traded fund?
• What are the three themes that active equity portfolio managers can use?
• What stock characteristics differentiate value-oriented and growth-oriented investment styles?
• What is style analysis and what does it indicate about a manager’s investment performance?
Chapter 17 - Equity Portfolio Management Strategies
• What techniques are used by active managers
in an attempt to outperform their benchmark?
• What are differences between the integrated,
strategic, tactical, and insured approaches to
asset allocation?
• How can futures and options be useful in
managing an equity portfolio?
Passive versus Active Management • Passive equity portfolio management
– Long-term buy-and-hold strategy
– Usually tracks an index over time
– Designed to match market performance
– Manager is judged on how well they track the target index
• Active equity portfolio management
– Attempts to outperform a passive benchmark portfolio on a risk-adjusted basis
An Overview of Passive Equity
Portfolio Management Strategies
• Replicate the performance of an index
• May slightly underperform the target index
due to fees and commissions
• Costs of active management (1 to 2 percent)
are hard to overcome in risk-adjusted
performance
• Many different market indexes are used for
tracking portfolios
Index Portfolio Strategy
Construction Techniques
• Full replication
• Sampling
• Quadratic optimization or
programming
Full Replication
• All securities in the index are
purchased in proportion to weights in
the index
• This helps ensure close tracking
• Increases transaction costs, particularly
with dividend reinvestment
Sampling
• Buys a representative sample of stocks in the
benchmark index according to their weights in
the index
• Fewer stocks means lower commissions
• Reinvestment of dividends is less difficult
• Will not track the index as closely, so there will
be some tracking error

and Portfolio Samples of Less Than 500 Stocks

Expected Tracking
Error (Percent)
Number of Stocks
Quadratic Optimization
(or programming techniques)
• Historical information on price changes and
correlations between securities are input
into a computer program that determines the
composition of a portfolio that will
minimize tracking error with the benchmark
• This relies on historical correlations, which
may change over time, leading to failure to
track the index
Methods of Index Portfolio
Investing
• Index Funds
– Attempt to replicate a benchmark index
• Exchange-Traded Funds
– EFTs are depository receipts that give investors a pro rata claim on the capital gains and cash flows of the securities that are held in deposit by a financial institution that issued the certificates
An Overview of Active Equity
Portfolio Management Strategies • Goal is to earn a portfolio return that
exceeds the return of a passive benchmark portfolio, net of transaction costs, on a risk-adjusted basis
• Practical difficulties of active manager
– Transactions costs must be offset
– Risk can exceed passive benchmark
Fundamental Strategies
• Top-down versus bottom-up approaches
• Asset and sector rotation strategies
Sector Rotation
• Position a portfolio to take advantage of the
market’s next move
• Screening can be based on various stock
characteristics:
– Value
– Growth
– P/E
– Capitalization
– Sensitivity to economic variables
Technical Strategies
• Contrarian investment strategy
• Price momentum strategy
• Earnings momentum strategy
Value versus Growth
• Growth stocks will outperform value
stocks for a time and then the
opposite occurs
• Over time value stocks have offered
somewhat higher returns than
growth stocks
Value versus Growth
• Growth-oriented investor will:
– focus on EPS and its economic
determinants
– look for companies expected to have rapid
EPS growth
– assumes constant P/E ratio
Value versus Growth
• Value-oriented investor will:
– focus on the price component
– not care much about current earnings
– assume the P/E ratio is below its natural
level
Style
• Construct a portfolio to capture one or more of
the characteristics of equity securities
• Small-capitalization stocks, low-P/E stocks,
etc…
• Value stocks appear to be underpriced
– price/book or price/earnings
• Growth stocks enjoy above-average earnings
per share increases
Does Style Matter?
• Choice to align with investment style
communicates information to clients
• Determining style is useful in measuring
performance relative to a benchmark
• Style identification allows an investor to
diversify by portfolio
• Style investing allows control of the total
portfolio to be shared between the investment
managers and a sponsor
Determining Style
• Style grid:
– firm size
– value-growth characteristics
• Style analysis
– constrained least squares
Benchmark Portfolios
• Sharpe
– T-bills, intermediate-term government bonds,
long-term government bonds, corporate bonds,
mortgage related securities, large-capitalization
value stocks, large-capitalization growth stocks,
medium-capitalization stocks, small-
capitalization stocks, non-U.S. bonds, European
stocks, and Japanese stocks
Benchmark Portfolios
• Sharpe
• BARRA
– Uses portfolios formed around 13 different
security characteristics, including variability in
markets, past firm success, firm size, trading
activity, growth orientation, earnings-to-price
ratio, book-to-price ratio, earnings variability,
financial leverage, foreign income, labor
intensity, yield, and low capitalization
Benchmark Portfolios
• Sharpe
• BARRA
• Ibbotson Associates
– simplest style model uses portfolios formed
around five different characteristics: cash (T-
bills), large-capitalization growth, small-
capitalization growth, large-capitalization
value, and small-capitalization value
Timing Between Styles
• Variations in returns
among mutual funds are
largely attributable to
differences in styles
• Different styles tend to
move at different times
in the business cycle
Asset Allocation Strategies • Integrated asset allocation
– capital market conditions
– investor’s objectives and constraints
• Strategic asset allocation
– constant-mix
• Tactical asset allocation
– mean reversion
– inherently contrarian
• Insured asset allocation
– constant proportion
Asset Allocation Strategies
• Selecting an allocation method depends on:
– Perceptions of variability in the client’s objectives and constraints
– Perceived relationship between the past and future capital market conditions
Using Futures and Options in
Equity Portfolio Management
• Systematic and unsystematic risk of equity
portfolios can be modified by using futures and
options derivatives
• Selling futures on the portfolio’s underlying
assets reduces the portfolio’s sensitivity to price
changes of the asset
• Options do not have symmetrical impact on
returns
The Use of Futures in Asset Allocation
• Allows changing the portfolio allocation quickly
to adjust to forecasts at lower transaction costs
• Futures can maintain an overall balance in a
portfolio
• Futures can gain exposure to international
markets
• Currency exposure can be managed using
currency futures and options
Using Derivatives in Passive
Equity Portfolio Management
• Futures and options can help control cash inflows and outflows from the portfolio
– Inflows - index contracts allow time to make investments
– Outflows - large planned withdrawal is made by selling securities, which causes an increase in cash holdings; futures can counterbalance this until the withdrawal
• Options can be sold to reduce weightings in sectors or individual stocks during rebalancing
Using Derivatives in Active
Equity Portfolio Management
• Modifying systematic risk
• Modifying unsystematic risk
