Abstract

Recent theories suggest that both risk and mispricing are associated with commonality in security returns, and that the loadings on characteristic-based factors can be used to predict future returns. We offer a parsimonious model which features: (1) a factor motivated by limited attention that is dominant in explaining short-horizon anomalies, and (2) a factor motivated by overconfidence that is dominant in explaining long-horizon anomalies. Our three-factor risk-and-behavioral composite model outperforms both standard models and recent prominent factor models in explaining a large set of robust return anomalies.

Complexity Aversion When Seeking Alpha

Abstract

I provide evidence that news’ complexity and sentiment affect investor attention to news and market reactions. Using field data with randomization from Seeking Alpha, I find standard-deviation increases in headline length (negativity) lead to 12%-fewer (2%-more) views. Effects are greater for less-sophisticated investors. Studying company-earnings-press-release headlines, and using the length of firms’ legal names to instrument headline lengths, I find standard-deviation increases in length lead to 7%-lower turnover, 60-basis-points-tighter-intraday-price ranges, and 15-basis-points-return underreactions, which reverse in three months. Complexity matters more for less-surprising news released on quieter days to less-sophisticated investors.

Abstract

We propose a theory of one of the most economically significant stock market anomalies, i.e. the ``profitability'' anomaly. In our model, investors forecast future profits using a signal and sticky belief dynamics. In this model, past profits forecast future returns (the profitability anomaly). Using analyst forecast data, we measure expectation stickiness at the firm level and find strong support for three additional predictions of the model: (1) analysts are on average more pessimistic for high profit firms, (2) the profitability anomaly is stronger for stocks which are followed by stickier analysts, and (3) it is also stronger for stocks with more persistent profits.
