We examine the trades of individual and professional investors around stock splits and find that splits bring about a significant shift in investor clientele. We find that a higher fraction of post-split trades are made by less sophisticated investors, as individual investors increase and...

In this paper, we find that existing classifications do a poor job at forecasting differences in future performance. We propose a different method for grouping mutual funds which is relatively impervious to strategic quot;gamingquot; of benchmarks. In particular, it captures active portfolio...

Over the years numerous portfolio performance measures have been proposed. In general they are designed to capture some particular enhancement that might result from active management. However, if a principal uses a measure to judge an agent, then the agent has an incentive to game the measure....

Our analysis of daily index fund flows indicates a strong contemporaneous correlation between fund inflows and S&P market returns. We also document a strong negative correlation between fund out flows and S&P market returns with the exception of outflows from a back-end load fund. These effects...

We test a Wall Street investment strategy known as "pairs trading" with daily data over the period 1962 through 1997. Stocks are matched into pairs according to minimum distance in historical normalized price space. We test the profitability of several trading rules with six-month trading...

It is now well known that the Sharpe ratio and other related reward-to-risk measures may be manipulated with option-like strategies. In this paper we derive the general conditions for achieving the maximum expected Sharpe ratio. We derive static rules for achieving the maximum Sharpe ratio with...

In this paper, we collect individual stock prices for NYSE stocks over the period 1815 to 1925 and individual dividend data over the period 1825 to 1870. We use monthly price and dividend information on more than 600 individual securities over the period to estimate a stock price index and total...
