Who has volatility information in the index options market?

Abstract

We examine volatility information embedded in the demand for options by analyzing data related to trades and investors. We find that overall demand for volatility in the options market does not predict stock market volatility but that foreign investors’ vega-weighted net demand conveys significant information about future volatility dynamics. Foreign investors use their superior volatility information by trading near-the-money options with high vega values.
