We analyze a comprehensive sample of more than 10,000 U.S. OTC stocks. We first show that the OTC market is a large, diverse, and dynamic trading environment with a rich set of regulatory and disclosure regimes, comprising venue rules and state laws beyond SEC regulation. We then exploit this...

Studying a comprehensive sample of stocks from the U.S. OTC market, we show that this market is a large and diverse trading environment with a rich set of regulatory and disclosure regimes, comprising venue rules and state laws beyond SEC regulation. We exploit this institutional richness to...

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,...

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...

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...

In this paper we note that unrelated research in the management and finance fields, if combined, makes predictions concerning board reforms in emerging countries. Specifically, outside directors' demographic characteristics that are salient to foreign investors should reduce stock price...

In this article, the Universal Approximation Theorem of Artificial Neural Networks (ANNs) is applied to the SABR stochastic volatility model in order to construct highly efficient representations. Initially, the SABR approximation of Hagan et al. [2002] is considered, then a more accurate...

We explore the effects of tax avoidance and tax risk on stock return volatilities of U.S. firms. We find that firms with very low and very high levels of tax avoidance and firms with high levels of tax risk have more volatile stock returns. We observe that tax avoidance primarily affects stock...

This paper studies the impact that pre-IPO cash flow volatility has on the initial and long-term value of a publicly traded firm. From the perspective of corporate risk management theory, higher cash flow volatility should reduce value in the form of higher borrowing costs, reduced investment,...

This study examines the accounting information uncertainty effects on corporate credit risk from the perspective of real earnings management (RM) activities by investigating 9,565 American bond observations from year 2001 to 2008. The main results show that the volatilities of RM activities...
