We estimate a heterogeneous agent model on five prominent equity investment styles - value, size, profitability, investment, and momentum - and find evidence for behavioral heterogeneity in expected return formation. Our model features two groups of boundedly rational investors, fundamentalists...

We measure investors' short- and long-term stock-return expectations using both options and survey data. These expectations at different horizons reveal what investors think their own short-term expectations will be in the future, or forward return expectations. While contemporaneous short-term...

We provide strong evidence that the dispersion of individual stock options trading volume across moneynesses (IDISP) contains valuable information about future stock returns. Stocks with high IDISP consistently underperform those with low IDISP by more than 1% per month. In line with the idea...

This paper illustrates that when CAPM is expanded to incorporate an investor base with heterogeneous risk aversions over a multi-period timeframe, a more realistic model is revealed which explains many return attributes previously considered to be anomalies. Investor concentrations in the market...

The efficient-market hypothesis (EMH) is one of the most important economic and financial hypotheses that have been tested over the past century. Due to many abnormal phenomena and conflicting evidence, otherwise known as anomalies against EMH, some academics have questioned whether EMH is...

This paper examines whether sell-side security analysts follow momentum or create momentum by themselves for recommending stocks. We employ an indirect method of testing the role of analysts by assigning projected recommendation scores for the neglected stocks to mitigate the so-called...

The analysis is focus on European market and test a presence structural break in year 2000 (financial services and markets act). We made an analysis of five portfolios over eight...

Past industry returns predict the cross section of industry returns, and this predictability is at its strongest at the one-month horizon (Moskowitz and Grinblatt 1999). We show that the cross section of factor returns shares this property, and that industry momentum stems from factor momentum....

Using a unique data set that contains the complete ownership structure of the German stock market, we study the momentum and contrarian trading of different investor groups. Foreign investors and financial institutions, and especially mutual funds, are momentum traders, whereas private...
