Earnings management is a key issue for financial reporting. The purpose of this paper is to derive a set of indices to measure the pervasiveness of earnings management (PEM) using the properties of quarterly accrual volatility. The PEM index can be viewed as a quality measure of financial...

We find that lower ex-ante earnings volatility leads to higher Post-Earnings Announcement Drift (PEAD). PEAD is a function of both the magnitude of an earnings surprise and its persistence. While prior research has largely investigated market reactions to the magnitude of the earnings surprise,...

This paper extends the variance decomposition framework of Campbell (1991), Campbell and Ammer (1993) and Vuolteenhao (2002) to address the relative value relevance of accruals news, cash flow news and expected return news in driving firm-level equity returns. The extension is based on the...

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)...

This paper examines whether financial statement information can predict future realized volatility incremental to the volatility implied by option market prices. Prior research establishes that option-implied volatility is a biased estimator of future realized volatility. I use an analytical...

We examine the association between accounting quality, which is used as a proxy for firm information risk, and the behavior of the term structure of implied option volatility around earnings announcements. By employing a large sample of US firms having options traded on their equity during...

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...

This study documents the prominent role of idiosyncratic risk in impeding arbitrage activities with regard to a new value-to-price anomaly. Adopting the theoretical foundation and empirical specification of Hwang and Sohn's (2010) real-option-based valuation model, we measure the intrinsic value...

High-frequency trading has become a dominant force in the U.S. capital market, accounting for over 70% of dollar trading volume. This study examines the implication of high-frequency trading for stock price volatility and price discovery. I find that high-frequency trading is positively...
