Financial studies on the herding effect have been very popular for decades, as detecting herding behavior helps to explain price deviations and market inefficiencies. However, studying the herding effect as a single influencing factor is believed to be insufficient to explain the changes in...

We distill tone from a huge assortment of NASDAQ articles to examine the predictive power of media-expressed tone in single-stock option markets and equity markets. We find that (1) option markets are impacted by media tone; (2) option variables predict stock returns along with tone; (3) option...

We develop a four-factor model intended to capture size, value, and credit rating transition patterns in excess returns for a panel of predominantly mid- and large-cap entities. Using credit transition matrices and rating histories from 48 US issuers, we provide evidence to support a...

Risk aversion theory is based on individuals' choice among risky assets with expected utility in its foundation. It is about investor behavior (i.e. investor choice), under normal circumstances, towards assets with various levels of risk. A positive and marginally diminishing relationship...

This paper provides evidence that the market does not efficiently incorporate expected returns implied by analyst price targets into prices. I use a novel decomposition to extract information and bias components from these analyst-expected returns and develop an asset pricing framework that...

This paper presents a present-biased general equilibrium model that explains many features of bond behavior. Present-biased investors increase (decrease) short-term (long-term) hedge demands compared to standard preferences. Hence, present bias drives up (down) short-term bond prices (yields)...

We examine the effect of investor attention spillover on stock return predictability. Using a novel measure, the News Network Triggered Attention index (NNTA), we find that NNTA negatively predicts market returns with a monthly in(out)-of-sample R-square of 5.97% (5.80%). In the cross-section, a...

Ungeheuer and Weber (2021, UW) propose a Comove measure, the fraction of weekly stock returns that are in the same direction as the market, and document that Comove positively predicts cross-sectional stock returns. We show that Comove is strongly negatively correlated with idiosyncratic...

Fractional trading (FT)—the ability to trade less than a full share—allows low-budget retail investors to trade high-priced stocks. This paper quantifies FT's impact on retail ownership and trading of high-priced stocks by exploiting its sequential introduction at four brokerage firms since...

We examine the asset pricing implications of regret theory. In our model, investors mentally represent a stock by the distribution of its past returns and evaluate it following regret theory. Investors feel the sensation of regret if their investment performs worse than an unchosen alternative...
