Momentum strategies have produced high returns and Sharpe ratios, and strong positive alphas relative to market models and other standard factors models. However, the returns to momentum strategies are highly skewed; they experience infrequent but strong and persistent strings of negative returns....

Motivated by behavioral theories, we test whether recent past performance of the momentum strategy (Past Momentum Performance--PMP) negatively predicts the performance of stale momentum portfolios. Following periods of top-quintile PMP, momentum portfolios exhibit strong reversals 2-5 years...

Despite their strong positive average returns across numerous asset classes, momentum strategies can experience infrequent and persistent strings of negative returns. These momentum crashes are partly forecastable. They occur in “panic” states – following market declines and when market...

We introduce a methodology to estimate the historical time-series of returns to investment in private equity funds. The approach requires only an unbalanced panel of cash contributions and distributions accruing to limited partners, and is robust to sparse data. We decompose private equity...

We study the nature of systemic sovereign credit risk using CDS spreads for the U.S. Treasury, individual U.S. states, and major European countries. Using a multifactor affine framework that allows for both systemic and sovereign-specific credit shocks, we find that there is considerable...

Individuals and asset managers trade aggressively, resulting in high volume in asset markets, even when such trading results in high risk and low net returns. Asset prices display patterns of predictability that are difficult to reconcile with rational expectations–based theories of price...
