The persistence of Risk-adjusted Mutual Fund Performance

The authors examine predictability for stock mutual funds using risk-adjusted returns. They find that past performance is predictive of future risk-adjusted performance. Applying modern portfolio theory techniques to past data improves selection and allows the authors to construct a portfolio of funds that significantly outperforms a rule based on past rank alone. In addition, they can form a combination of actively managed portfolios with the same risk as a portfolio of index funds but with higher mean return. The portfolios selected have small but statistically significant positive risk-adjusted returns during a period where mutual funds in general had negative risk-adjusted returns.

The Adequacy of Investment Choices Offered By 401K Plans

Defined-contribution plans represent a major organizational form for investors’ retirement savings. Today more than one third of all workers are enrolled in 401K plans. In a 401K plan, participants select assets from a set of choices designated by an employer. For over half of 401K-plan participants, retirement savings represent their sole financial asset. Yet to date there has been no study of the adequacy of the choices offered by 401K plans. This paper analyzes the adequacy and characteristics of the choices offered to 401K-plan participants for over 400 plans. We find that, for 62% of the plans, the types of choices offered are inadequate, and that over a 20-year period this makes a difference in terminal wealth of over 300%. We find that funds included in the plans are riskier than the general population of funds in the same categories. We study the characteristics of plans that are associated with adequate investment choices, including an analysis of the use of company stock, plan size, and the use of outside consultants. When we examine one category of investment choices, S&P 500 index funds, we find that the index funds chosen by 401K-plan administrators are on average inferior to the S&P 500 index funds selected by the aggregate of all investors.

Marginal Stockholder Tax Effects and Ex-Dividend-Day Price Behavior: Evidence From Taxable Versus Nontaxable Closed-End Funds

Almost all research on the movement of stock prices on ex-dividend days has found that prices decline by less than the dividend. Though this is consistent with tax effects, several papers have argued that this phenomenon could be caused by market microstructure effects. In this paper we make use of a natural experiment that provides support for the tax explanations of ex-dividend behavior. Some closed-end funds have taxable, and some have nontaxable, dividend distributions. Both types are subject to taxes on capital gains. The implication of this for ex-dividendday price behavior is very different between these two types of funds if taxes matter. This paper demonstrates that the direction of ex-dividendday price behavior is consistent with a tax explanation and that ex-dividend-day price behavior changes, as theory would suggest, with changes in the tax law.

Why Do Closed-End Bond Funds Exist? An Additional Explanation for the Growth in Domestic Closed-End Bond Funds

This paper provides a new explanation for why closed-end bond funds coexist along with otherwise identical open-end bond funds. Closed-end bond funds offer investors the opportunity to leverage their fixed income investment at very low borrowing rates and are attractive to investors for this reason. We find that differences in leverage are reflected in the discount on closed-end bond funds in a manner consistent with the advantage of leverage.

The Performance of Separate Accounts and Collective Investment Trusts

Despite the size and importance of separately managed accounts (SMAs) and collective investment trusts, their characteristics and performance have not been studied in detail. We show that separate account performance is similar to that of index funds and superior to that of actively managed mutual funds. Management supplies a benchmark for each separate account. When the management-selected benchmark is used to measure performance, performance is significantly overstated. Despite this, investors react to differences in performance from the management-preferred benchmark in choosing among SMAs. Finally we find variables that explain both the cross section of alphas and the cross section of cash flows.

An Examination of Mutual Fund Timing Using Monthly Holdings Data

In this paper we use data on the monthly holdings for a set of mutual funds to study the timing ability of these funds. By examining monthly holdings we are able to see how management changes the risk parameters and industry holdings in a fund and to examine how this contributes to timing. We find evidence that timing decisions result in a decrease in performance, whether timing is measured using conditional or unconditional sensitivities. Likewise, sector rotation decisions also result in lower returns. Examining the results for individual sectors shows that the majority of the negative impact on returns from sector rotation comes about because of a fund changing exposure to high-tech stocks.

Applications of Markowitz Portfolio Theory To Pension Fund Design

Harry Markowitz (1952) published an article that revolutionized the way the world thought about investments, the investment process, and measuring and predicting portfolio performance. The impact of Harry’s 1952 article and his research that followed have been extraordinary. There is no doubt that this work is one of a handful of major breakthroughs that have changed not only the way we think about the world of finance, but also the way the world of finance functions.
