Implied Volatility and Future Portfolio Returns
The level of the Chicago Board Options Exchange Volatility Index (VIX) has been shown to predict returns on equity indexes, implying either that VIX variables are priced risk factors or that markets are inefficient. In the October 2007 Journal of Banking and Finance, Banerjee, Doran and Peterson show that this relationship is strongest for high-beta portfolios.
Studies have shown that high volatility index scores are positively related to future stock market returns. In an efficient market, an observable variable such as the VIX should not have predictive power. The authors confirm that the predictive power exists, and offer support for both the market inefficiency and the priced risk arguments.
