The idiosyncratic volatility (IVOL) anomaly exhibits strong calendar effects. The negative relation between IVOL and the next month return obtains mainly in the third week of the month. The IVOL-return relation is generally negative on Mondays and positive on Fridays. However, the positive...

This paper examines the diversification benefits of iShares in comparison to closed-end country funds (CECFs) and American Depository Receipts (ADRs) between April 1996 and December 2013. iShares are country-specific exchange traded funds that track specific Morgan Stanley Capital International...

Socially responsible (SR) institutions tend to focus more on the ESG performance and less on quantitative signals of value. Consistent with this difference in focus, we find that SR institutions react less to quantitative mispricing signals. Our evidence suggests that the increased focus on ESG...

We uncover new return predictability in the cross-section of delta-hedged equity options. Expected returns of writing delta-hedged calls are negatively correlated with current stock price, firm profit margin and profitability, but positively correlated with firm cash holding, cash flow variance,...

We find that option expensiveness, as measured by delta-hedged option returns, is higher for low-ESG stocks, indicating that investors pay a premium in the option market to hedge ESG-related uncertainty. We estimate this ESG premium to be about 0.3% per month. All three components of ESG...

Option-based measures can predict underlying stock returns, due to differences in price discovery and price pressure effects between options and underlying stocks. We investigate stock return predictability by various option price-based measures using REITs. REITs are more transparent and...

Socially responsible (SR) institutions tend to focus more on the ESG performance and less on quantitative signals of value. Consistent with this difference in focus, we find that SR institutions react less to quantitative mispricing signals. Our evidence suggests that the increased focus on ESG...

We find that single-name options trading increases the absolute level of information content of prices (stock price informativeness). We confirm our results through instrumental variable approach to control for potential endogeneity. We further show causality by using a difference-in-difference...
