Modern asset pricing theory predicts an unambiguously positive relationship between volatility and expected returns. Empirically, however, realized volatility in the past often predicts expected returns in the future with a negative sign, as exemplified by the volatility-managed portfolios of...

The author analyzes the statistics of words and phrases related to financial market trading practices in millions of volumes from Google's book collection and available at Google Ngram Viewer. In recent almost 30 years, as the analyzed data shows, the scholars and practitioners' interest in the...

We investigate whether increased investor demand for financial information arising from higher market uncertainty leads to greater media coverage of earnings announcements. We also investigate whether greater coverage during times of higher uncertainty further destabilizes financial markets...

The role of public sentiment in stock market volatility has recently become increasingly relevant. Twitter, in theory, offers an inexpensive way to measure real-time public sentiment. We take advantage of a natural experiment to assess the potential improvement that social media adds to forecast...

We study the equilibrium implications on asset prices of institutions' trading with sentiment-driven retail investors. In the model, both the benchmarking concerns of institutions and the (irrational) optimism of retail investors boost the aggregate demand for a stock. We show that the ensuing...

This paper examines the distributional properties of cryptocurrency realized variation measures (RVM) and the predictability of RVM on future returns. We show the cryptocurrency volatility persistence and the importance of the asymmetry on volatility forecasting. Signed jumps variations...

Variance after-effect is a perceptual bias in the dynamic assessment of variance. Experimental evidence shows that perceived variance is decreased after prolonged exposure to high variance and increased after exposure to low variance. We introduce this effect in an otherwise standard financial...

Volatility is an important component of asset pricing; an increase in volatility on markets can trigger changes in the risk distribution of financial assets. In conventional financial theory, investors are considered to be rational and any changes in relevant risk are assumed to be a result of...

High idiosyncratic volatility (IV) stocks follow predictable return pattern after exhibiting large ex ante returns: a period of underreaction and low returns is superseded by persistent high returns. This pattern is robust and economically significant: it may be interpreted as informationally...
