No. 732: How Does the Market Variance Risk Premium Vary over Time? Evidence from S&P 500 Variance Swap Investment Returns
October 27, 2014
We explore whether the market variance risk premium (VRP) can be predicted. First, we propose a novel approach to measure VRP which distinguishes the investment horizon from the variance swap's maturity. We extract VRP from actual rather than synthetic S&P 500 variance swap quotes, thus avoiding biases in VRP measurement. Next, we find that a deterioration of the economy and of the trading activity, increases VRP. These relations hold both in- and out-of-sample for various maturities and investment horizons and they are economically significant. Volatility trading strategies which condition on the detected relations outperform popular buy-and-hold strategies even after transaction costs are considered.
