We examine the relation between stock volatility and asymmetric information empirically. We use two proxies of information asymmetry: institutional ownership and analyst coverage. We find that firms covered by more analysts are more likely to have less volatile returns. A significant and...

The arrival of new information helps financial markets to value assets, but it may has the side-effect of increasing their volatilities. A better knowledge of the mechanism that links relevant news and stock prices would help both private and institutional agents to improve the calibration of...

The same firm characteristics that help explain cross-sectional variation in expected stock returns, such as size, book-to-market and the earnings yield, also help explain cross-sectional variation in returns to trading in option-implied stock return volatility. This empirical phenomenon is...

Purpose – The purpose of this paper is to examine securities analyst independence in China's capital market and the effect on analyst independence of institutional investors' shareholding and separation between control rights and cash flow rights of ultimate...

We explore the impact of earnings announcements on equity markets, using intraday price data for the DJIA stocks. We find on a daily basis, an abnormally high volatility only within one day following the overnight announcement. On an intraday basis, a striking volatility spike stands out during...

This study proposes and validates “other information” in analysts' forecasts as a legitimate proxy for future cash flows, and examines its incremental role in explaining stock return volatility. We suggest that “other information” contains information about fundamentals beyond that...

The primary aim of this study is to investigate the stock return volatility surrounding management earnings forecasts. Disclosure by managers of expected earnings are particularly important communications, and as such, it is important to understand the capital market implications surrounding...

This paper examines the relation between firm-level implied volatility skew and the likelihood of extreme negative events, or crash risk. I show that volatility skew identifies which firms are likely to experience crashes, but only in short-window earnings announcement periods. The predictive...

We test the proposition in Johnstone (2016) that new information may lead to higher, rather than lower, uncertainty about firms' future payoffs. Based on the Bayesian rule, we hypothesize earnings news that is inconsistent with investors' prior belief will lead to higher market uncertainty....

Financial crises are typically marked by substantial increases in ambiguity where prices appear to decouple from fundamentals. Consistent with ambiguity-based asset pricing theories, we find that ambiguity concerns are more severe for firms with higher pre-crisis earnings volatility, causing...
