Angel investors invest billions of dollars in thousands of entrepreneurial projects annually, far more than the number of firms that obtain venture capital. Previous research has calculated realized internal rates of return on angel investments, but empirical estimates of expected returns have...

Previous research calculates realized internal rates of return on angel investments but does not estimate expected returns. We present the first estimates of expected returns on angel investments by applying a consistent statistical framework to a new data set. Our sample spans 1972 to 2007 with...

This paper analyzes the interaction between investor overconfidence, share turnover, return volatility and the disposition effect. I create a measure for investor overconfidence using posted price target updates retrieved from Yahoo!Finance online message boards. I find that posters are slow to...

We measure herding of trading activities by regressing individual order imbalances on market wide, industry wide, and dealer wide order imbalances. We find that stocks whose trading activities herd more have higher sensitivity of their returns to order imbalances. Investors demand compensations...

The correlation of returns for various equity asset classes has been high. In addition, the range or "dispersion" of returns across asset classes - and across sectors within those asset classes - has been low. These factors have made it difficult for active managers to outperform. But dispersion...

We show that immediate and delayed abnormal returns following earnings announcement surprises differ across market states. Immediate abnormal returns are more sensitive to earnings surprises in down markets, while delayed abnormal returns are less sensitive; underreaction is attenuated in down...

Financial markets are typically characterized by high (low) price level and low (high) volatility during boom (bust) periods, suggesting that price and volatility tend to move together with different market conditions/states. By proposing a simple heterogeneous agent model of fundamentalists and...

Using stocks traded on the NYSE, AMEX and NASDAQ for the period of 1964 to 2009, this study demonstrates that, while momentum prevails among small stocks, momentum and reversals coexist among large stocks for a holding period of up to six months. The momentum/reversal divide is along the...

We propose a model of volatility tail behavior, in which the pricing measure dominates the physical measure in both tails of the volatility distribution and, hence, the derived pricing kernel exhibits an increasing and decreasing region in the volatility dimension. The model features investors...
