Abstract:     
We consider a new nonparametric estimator of the leverage effect, which uses the data on stock prices as well as a certain volatility instrument, such as the CBOE volatility index (VIX) or Black-Scholes implied volatility. The theoretical justification for the new estimator exploits the relationship between the volatility instrument and the spot volatility, together with a certain invariance property of the spot correlation. We derive the asymptotic distribution of the estimator. We compare this instrument-based estimator with the nonparametric price-only leverage estimator, for which we also derive the asymptotic distribution. The instrument-based estimator has a faster rate of convergence. We demonstrate in simulations and empirically that the instrument-based estimator is substantially more precise than the price-only estimator. Finally, we use the new estimator to provide time series of monthly leverage effects of the S&P 500 index from 2003 to 2012 using two different volatility instruments. We also find that the credit risk, liquidity, and the debt-to-equity are important determinants of the leverage effect.
