We examine the short-term dynamic relation between the S&P 500 (Nasdaq 100) index return and changes in implied volatility at both the daily and intraday level. Neither the leverage hypothesis nor the volatility feedback hypothesis adequately explains the results. Alternatively, we propose that...

We develop a general model to price VIX futures contracts. The model is adapted to test both the constant elasticity of variance (CEV) and the Cox–Ingersoll–Ross formulations, with and without jumps. Empirical tests on VIX futures prices provide out-of-sample estimates within 2% of the...

An important component of theoretical CBOE Volatility Index (VIX) futures prices is a term correcting for the negative convexity of the square root function by subtracting from the forward-starting variance swap rate an estimate of the future volatility of VIX futures prices. In the same fashion...

We investigate whether employing individual commodity futures provides a superior optimized risk-return strategy relative to an equity portfolio, in spite of recently increasing correlations between commodity and equity markets. We first construct Markowitz mean-variance optimized portfolios of...

We examine the return‐implied volatility relation by employing “commodity” option VIXs for the euro, gold, and oil. This relation is substantially weaker than for stock indexes. We propose several potential reasons for these unusually weak results. Also, gold possesses an unusual positive...

The study shows critical roles of firm-specific information on herd behavior, which is underexplored in prior literature, albeit an increasing impact of firm-specific information on asset pricing. The main finding demonstrates that three of four selected measures of firm-specific information...

This study uses the Worldwide Governance Indicators (WGI) developed by the World Bank to examine a cross-country corporate governance spillover effect among the G7, BRICS, and GIIPS countries during the period of 1996-2014. The panel unit root tests show stationary panel time series properties...

Using the panel vector autoregression (VAR) method, this paper documents relationships between investor attention and stock market activities; i.e., return, volatility, and trading volume, respectively. In sum, bidirectional dynamic interdependence of the SVI–stock market activities...

Purpose: Exploiting an exogenous regulatory shock and a novel measure of asset redeployability, we explore the effect of independent directors on asset redeployability. In particular, we employ an innovative measure of asset redeployability recently developed by Kim and Kung (2017). This novel...
