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 sponsorDetermining Style Style grid: firm size value-growth characteristics Style analysis constrained least squaresBenchmark 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 stocksBenchmark 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 capitalizationBenchmark 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 valueTiming 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 cycleAsset Allocation Strategies Integrated asset allocation capital market conditions investors objectives and constraints Strategic asset allocation constant-mix Tactical asset allocation mean reversion inherently contrarian Insured asset allocation constant proportionAsset Allocation Strategies Selecting an allocation method depends on: Perceptions of variability in the clients objectives and constraints Perceived relationship between the past and future capital market conditionsUsing 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 portfolios underlying assets reduces the portfolios sensitivity to price changes of the asset Options do not have symmetrical impact on returnsThe 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 optionsUsing 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 rebalancingUsing Derivatives in Active Equity Portfolio Management Modifying systematic risk Modifying unsystematic riskThe InternetInvestments OnlineEnd of Chapter 17Equity Portfolio Management StrategiesFuture topicsChapter 18 Bond Fundamentals
