We use a two-year panel of individual accounts in an S&P 500 index mutual fund to examine the trading and investment behavior of more than 91 thousand investors who have chosen a low-cost, passively managed vehicle for savings. This allows us to characterize investors' heterogeneity in terms of...

We provide an exploratory investigation of mutual funds' investment styles. Funds' styles tend to cluster around a broad market benchmark. When funds deviate from the benchmark they are more likely to favor growth stocks with good past performance. There is some consistency in styles, although...

Using a large sample of institutional investors' private equity investments in venture and buyout funds, we estimate the extent to which investors' skill affects returns from private equity investments. We first consider whether investors have differential skill by comparing the distribution of...

The literature has not unambiguously established that a positive alpha, as traditionally measured, means that an investor would want to buy a fund. However, when alpha is defined using the client's marginal utility function, a client faced with a positive alpha would generally want to buy. When...

The level of diseconomies of scale in asset management has important implications for tests of manager skill and the expected level of performance persistence. To identify the causal impact of fund size on future returns, we exploit the fact that small differences in returns can cause discrete...

Since the after-fee returns of funds-of-funds are, on average, lower than hedge fund returns, it is easy to conclude that funds-of-funds do not add value compared to hedge funds. However, funds-of-funds should not be evaluated relative to hedge fund returns in publicly reported databases....

We document that the observed persistence amongst the worst performing actively managed mutual funds is attributable to funds that have performed poorly both in the current and prior year. We demonstrate that this persistence results from an unwillingness of investors in these funds to respond...

The returns to hedge funds and other alternative investments are often highly serially correlated in sharp contrast to the returns of more traditional investment vehicles such as long-only equity portfolios and mutual funds. In this paper, we explore several sources of such serial correlation...

This paper uses data on actual returns on taxable bonds, tax-exempt bonds, and a small sample of equity mutual funds over the 1962-1998 period to compare two asset location strategies for retirement savers. The first strategy gives priority to holding equities, through equity mutual funds, in a...

This paper reconsiders the literature on tax options by examining the ability to defer net capital gains realizations within an equity portfolio whose constituents change over time. Unlike previous studies on the value of tax options, this paper examines after-tax returns to shareholders within...
