T ax-efficient investing is both a challenge and an opportunity for the investment management industry. Few firms seem to recognize the importance of taxes; the same is true for many taxable investors. Although taxes impose material constraints and costs in the investment process, taxable investing has not received much attention from academics, practitioners, and investors. The investment world largely assumes tax-exempt investors. Portfolio management and perfbrmance measurement are generally inaerent to the effect of taxes on the investors who pay them. These facts are not surprising, as the tax-exempt segment is not only larger but also easier to reach than the taxable one. For taxable investors, the name of the game is to stay in the game. Taxable investors face several issues that those who are taxexempt do not need to address. Beyond the pleasures of maintaining meticulous records and completing forms for various taxing authorities, taxable entities should use hfferent strategies from those that operate in an environment without the negative cash flow of taxes. Jeffrey and Arnott [1993] demonstrate the importance of reducing turnover to a very low percentage. The power of compoundmg is one of the most significant aspects of taxable investing. Exhibit 1 displays pretax and after-tax returns of several investment styles using 1 actual returns and dstribution data from Morningstar over tenand twenty-year spans. An important aspect of this information is that it reflects how managers act within their respective styles. Among the equity styles, growth stocks have the highest pretax and after-tax returns. The growth style has the highest tax efficiency (after-tax returns as a percentage of pretax returns), but also the most volathty. A value approach (represented by the equity income style) has lower returns and tax efficiency but less volatility. These findings are noteworthy, given several studies that conclude that a value approach is superior. Whde it is beyond the scope of t h s article to address this issue, several factors could explain t h s Ifference. For diversification and other reasons, value managers may not exclusively own the lowest price-tobook or price-to-earnings companies. Alternatively, growth or “glamour” managers may invest in not only the most expensive stocks, but also those with more modest valuations. Growth managers, with their lower yields relative to other equity styles, have tax arbitrage working in their favor, as capital gains are taxed at a lower rate than ordmary income for most investors. The difference in the pretax and after-tax numbers for the equity styles is staggering. Consistent with Jeffrey and Arnott, we find that there is real money in increased tax efficiency. For example, if a
