Passive investing, particularly in emerging markets, has become an increasingly popular means of quick, “diversified” exposure to a particular segment of the markets. Flows into passive emerging market products have been so strong that assets in exchange-traded funds (ETFs) designed to...

Over the years, Institute research has shown active managers, even the best-performing ones, suffered periods of weak returns relative to benchmarks and their peers. But underperformance, up to three years, had relatively little impact on the best-performing funds' ability to deliver success...

We examine how active share—the extent to which a portfolio's holdings differ from its benchmark's holdings—affects the performance, risk management, and flows of bond mutual funds. Measuring active share at both the issue and issuer level, the average bond fund has an issue-level...

In this paper we examine the differences in aggregate ownership of stocks held by passive equity funds and active equity funds and in the characteristics of stocks held by these funds. We find that holdings of passive funds do not mirror the holdings of active funds. There are systematic...

Just over 20 years have passed since the publication of Carhart's landmark 1997 study on mutual funds. Its conclusion—that the data did “not support the existence of skilled or informed mutual fund portfolio managers”—was the capstone of an academic literature beginning with Jensen...

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...

We examine the performance of mutual funds whose managers simultaneously manage portfolios with performance-based incentive fees for three account types: mutual funds, hedge funds, and separate accounts. Importantly, our dataset is free of selection bias because it is hand collected from...

The prices of exchange-traded funds can deviate significantly from their net asset values, on average fluctuating within a band of about 200 basis points, in spite of the arbitrage mechanism that allows authorized participants to create and redeem shares for the underlying portfolios. The...

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...
