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...

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....

I propose to use volatility to infer opportunistic insider sales. I argue that insider sales occurring when volatility is low are suspicious and that these suspicious sales are likely to be driven by insiders’ private information for the following reasons. Suppose that insider sales are not...

We examine the impact of accounting quality, used as a proxy for information risk, on the behavior of equity implied volatility around quarterly earnings announcements. Using US data during 1996-2010, we observe that lower (higher) accounting quality significantly relates to higher (lower)...

The purpose of our study is to further understand managerial incentives that affect the volatility of reported fiscal-year earnings. We do this by examining income smoothing based on pseudo fiscal years. For each firm, we create pseudo-year earnings using four consecutive quarters other than the...
