Passive investing, particularly in emerging markets, has become an increasingly popular means of quick, “diversified” exposure to a particular segment of the markets. Defensive investors, as Benjamin Graham noted, would be best served owning a diversified list of leading companies. Yet it's...

Value investors generally characterize themselves as the grown ups in the investment world, unswayed by perceptions or momentum, and driven by fundamentals. While this may be true, at least in the abstract, there are at least three distinct strands of value investing. The first, passive value...

We propose a measure of dispersion in fund managers beliefs about future stock returns based on their active holdings, i.e., deviations from benchmarks. We fi nd that both the level of and the change in dispersion positively predict subsequent stock returns on a risk-adjusted basis. This effect...

We use price pressure resulting from purchases by mutual funds with large capital inflows to identify overvalued equity. This is a relatively exogenous overvaluation indicator as it is associated with who is buying, buyers with excess liquidity, rather than what is being purchased. We document...

Theoretical models imply fund size and performance should be negatively linked. However, empiricists have failed to uncover consistent support for this negative relation. Using a new econometric framework which includes fund-specific sensitivities to decreasing returns to scale, we find a both...

Final working paper version. "" Published version: The Review of Financial Studies, Volume 31, Issue 7, July 2018, pp. 2499–2552. Past fund performance does a poor job of predicting future outcomes. The reason is noise. Using a random effects framework, we reduce the noise by pooling...

A closet indexer is more likely to meet a value-weighted investment benchmark by value-weighting the portfolio. Following this intuition, we introduce a simple measure of active management, the absolute difference between the value weights and the actual weights held by a fund, averaged across...

I study the market for lending and borrowing securities in the United States. I find that by making securities available for borrowing, mutual funds acquire information about short selling, which they exploit for trading. Funds with discretion in their investment choices rebalance their...

Risk-neutral valuation is used to value a portfolio and decompose it into the components accruing to its stakeholders. The analysis incorporates managers' expected performance and contract renewal issues. A managed portfolio's economic value is shown to differ from its net asset value. A better...

We use risk-neutral valuation to value a portfolio and decompose the value into the components accruing to its stakeholders - service providers, portfolio managers, and the owners. The analysis incorporates managers' expected performance and contract-renewal issues. It provides a paradigm for...
