We introduce a new measure of active portfolio management, Active Share, which represents the share of portfolio holdings that differ from the benchmark index holdings. We compute Active Share for domestic equity mutual funds from 1980 to 2003. We relate Active Share to fund characteristics such...

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...

On the surface, hedge funds seem to have much higher fees than actively managed mutual funds. However, the true cost of active management should be measured relative to the size of the active positions taken by a fund manager. A mutual fund combines active positions with a passive position in...

We investigate the return premium on stocks with high earnings quality using a broad and recent global dataset covering all developed markets from 7/1988 to 6/2012. We find that a simple strategy that is long stocks with high earnings quality and short stocks with low earnings quality produces a...

I sort domestic all-equity mutual funds into different categories of active management using Active Share and tracking error. I find that over my sample period until the end of 2009, the most active stock pickers have outperformed their benchmark indices even after fees and transaction costs. In...

Standard Fama-French and Carhart models produce economically and statistically significant nonzero alphas, even for passive benchmark indices such as the S&P 500 and Russell 2000. We find that these alphas arise primarily from the disproportionate weight the Fama-French factors place on small...

This paper empirically investigates the index premium and its implications from 1990 to 2005. First, we find that the price impact has averaged 8.8% and 4.7% for additions to the Samp;P 500 and Russell 2000, respectively, and -15.1% and -4.6% for deletions. The premia have been growing over...
