We examine the effect of earnings surprises on changes in information asymmetry. We hypothesize and find that asymmetry is lower (higher) in the quarter following positive (negative) earnings surprises compared to firms that meet the consensus analyst earnings forecast. The relations between...

Investors in hedge funds and commodity trading advisors [CTA s] are naturally concerned with risk as well as return. In this paper, we investigate risk of hedge funds and CTA s in light of managerial career concerns. We find an association between past performance and risk levels consistent with...

Empirical analysis of rates of return in Finance implicitly condition on the security surviving into the sample. We investigate the implications of such conditioning on the time series of rates of return. In general this conditioning induces a spurious relationship between observed return and...

We propose a new empirical approach to determination of mutual fund styles. This approach is simple to apply, yet it captures nonlinear patterns of returns that result from virtually all active portfolio management styles. We find that the largest equity fund category, acirc;not;SGrowthacirc;not;?...

In this paper, we investigate risk of hedge funds and CTA s in light of managerial career concerns. We find an association between past performance and risk levels consistent with...

Two major conclusions follow from this very careful study. First, sophisticated prediction tools do not fare well relative to naive models predicting return based on past sample means. Second, there appear to be short-lived episodes of quite limited return predictability. These conclusions are...

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...

We explore performance persistence in mutual funds using absolute and relative benchmarks. Our sample, largely free of survivorship bias, indicates that relative risk-adjusted performance of mutual funds persists, however persistence is mostly due to funds that lag the Samp;P 500. A profit...
