We test the hypothesis that retail investors' attraction to lottery stocks induces overvaluation, and is amplified by high attention and social interactions. The lottery premium (negative abnormal returns) is stronger for high-retail-ownership stocks—especially those that also have high...

We establish key stylized facts about the post-crisis evolution of trading and pricing of credit default swaps. Using supervisory contract-level data, we document that dealers become net buyers of credit protection starting in the second half of 2014, both through reducing the amount of...

We document that the variation in market liquidity is an important determinant of momentum crashes that is independent of other known explanations surfaced on this topic. This relationship is driven by the asymmetric large return sensitivity of short-leg of momentum portfolio to changes in...

We provide detailed descriptions, including over 550 mathematical formulas, for over 150 trading strategies across a host of asset classes (and trading styles). This includes stocks, options, fixed income, futures, ETFs, indexes, commodities, foreign exchange, convertibles, structured assets,...

Recent research shows that a high wage gap between managers and workers identifies better-performing firms, but the stock market does not seem to price this information. In this paper, we show that not all investors neglect pay inequality. Using a unique data set on German firms' employee...

This paper explains and extends my 2002 paper. It presents a return factor of illiquid-minus-liquid stocks, called IML, which provides a time series of the illiquidity premium. The risk-adjusted predicted return on IML is lower in the period that follows my 2002 paper but it is still...

Nowadays, the social media play a central role not only in "de-asymmetrizing" the information between firms and investors but also in influencing the emotional response to this information. The social media have provided firms with the opportunity to construct their image and stimulate...

Warren Buffett suggested that the ratio of the market value of all publicly traded stocks to the Gross National Product could identify potential overvaluations and undervaluations in the US equity market. We investigate whether this ratio is a statistically significant predictor of equity market...

I investigate whether or not the multi-period trades of financial institutions cause mispricing in the stock market. After controlling for the magnitude and trends in institutional trades, I find evidence consistent with institutional trades pushing prices away from fundamentals. Stocks heavily...

We study asset prices and portfolio choice with overlapping generations, where the young disregard history to learn from own experience. Disregarding history implies less precise estimates of output growth, which in equilibrium leads the young to increase their investment in risky assets after...
