The SEC recently required a two-page summary of risk factor disclosures with the purpose of improving the decision-usefulness of firm risk factor disclosures. This study tests the usefulness to investors of (1) this new requirement and (2) a novel proposal that involves hyperlinking financial...

In response to the unprecedented uncertain rare events of the last decade, we derive an optimal portfolio choice problem in a semi-closed form by integrating price diffusion ambiguity, volatility diffusion ambiguity, and jump ambiguity occurring in the traditional stock market and the...

Risk is one of the key aspects in financial decision-making and therefore an integral part of the behavioral economics and finance literature. Focusing on the conceptualization of the term "risk", which researchers have addressed from numerous angles, this comment aims to offer a critical...

In this paper, I analyse whether the level of uncertainty in the financial markets affects the previously demonstrated relationship between media sentiment and stock market outcomes. I capture media sentiment by analysing the tone of the textual data from the New York Times stock market column...

The joint-hypothesis problem casts doubt on the results of market efficiency research. Specifically, it is hard to assess to what extent financial markets reflect economic fundamentals or mispricing. To address this issue, we study price formation in a large virtual asset market where...

The effects of sentiment should be strongest during times of heightened valuation uncertainty. As such, we document a significant amplifying role for market uncertainty in the relation between sentiment and aggregate investment. A one-standard-deviation increase in uncertainty more than doubles...

Using a news-based gauge of geopolitical risk, we study its role for asset pricing in global emerging markets. We find that changes in risk positively predict future stock returns. The countries with the highest increase in geopolitical uncertainty outperform their counterparts with the lowest...

This experimental study investigates the impact of affective attitudes on risk and return estimates of stocks. Participants rate well-known blue-chip firms on an affective scale and forecast risk and return of the firms' stock. We find that positive affective attitudes lead to a prediction of...

Contrary to the theoretical principle that higher risk is compensated with higher expected return, the literature shows that low-risk stocks outperform high-risk stocks. Using a large-scale household dataset, we provide an explanation for this puzzling result that the anomalous negative...
