This study examines whether conditional skewness forecasts of the underlying asset returns can be used to trade profitably in the index options market. The results indicate that a more general skewness‐based option‐pricing model can generate better trading performance for strip and strap...

Variation in idiosyncratic return volatility from 1978 to 2009 is attributable to discretionary accrual volatility and the correlation between premanaged earnings and discretionary accruals reflective of information quality across firms. These results are robust to controls for firm operating...

We develop conditional alpha performance measures that are consistent with conditional mean-variance analysis and the magnitude and sign of the implied true conditional time-varying alphas. The sequence of conditional alphas and betas is estimable from surprisingly simple unconditional...

This paper examines the determinants of exchange rate regime of a country. A competing risks model (CRM) is estimated. It is found that the way a country exits a fixed exchange rate regime is affected nonlinearly by the duration of the peg. In addition, countries with a lower growth rate of...

This paper explores the effects of price limits on the stock market of China during global market turmoils. The characteristics of stocks that hit the price limits more frequently under market turmoil are investigated. It is found that the price limit system increases volatility significantly...

This study empirically tests how and to what extent the choice of the sampling frequency, the realized volatility (RV) measure, the forecasting horizon and the time‐series model affect the quality of volatility forecasting. Using highly synchronous executable quotes retrieved from an...

This study derives optimal hedge ratios with infrequent extreme news events modeled as common jumps in foreign currency spot and futures rates. A dynamic hedging strategy based on a bivariate GARCH model augmented with a common jump component is proposed to manage currency risk. We find...

GARCH-jump models of metal price returns, while allowing for sudden movements (jumps), apply the same specification of the jump component in both 'bear'and 'bull' markets. As a result, the more frequent but relatively small jumps that occur in both bear and bull markets dominate the...

This work endeavors to study the long-range dependence of the international diamond market. The results from the modified R/S statistic suggest that diamond returns do not have long memory, while strong evidence is found for long memory in diamond volatilities.
