Abstract We show that the prices of risk for factors that are nonlinear in the market return can be obtained using index option prices. The price of coskewness risk corresponds to the market variance risk premium, and the price of cokurtosis risk corresponds to the market skewness risk premium. Option-based estimates of the prices of risk lead to reasonable values of the associated risk premia. An analysis of factor models with coskewness risk indicates that the new estimates of the price of risk improve the models’ performance compared with regression-based estimates.

This study investigates a forecasting power of volatility curvatures and risk neutral densities implicit in KOSPI 200 option prices by analyzing minute by minute historical index option intraday trading data from January of 2007 to January of 2011. We begin by estimating implied volatility functions and risk neutral price densities based on non-parametric method every minute and by calculating volatility curvature and skewness premium. We then compare the daily rate of return of the signal following trading strategy that we buy (sell) a stock index when the volatility curvature or skewness premium increases (decreases) with that of an intraday buy-and-hold strategy that we buy a stock index on 9:05AM and sell it on 2:50PM. We found that the rate of return of the signal following trading strategy was significantly higher than that of the intraday buy-and-hold strategy, which implies that the option prices have a strong forecasting power on the direction of stock market. Another finding is that the information contents of option prices disappear after three or four minutes.

We develop a tractable dynamic model of an index option market maker with limited capital. We solve for the variance risk premium and option prices as a function of the asset dynamics and market maker option holdings and wealth. The market maker absorbs end users’ positive demand and requires a more negative variance risk premium when she incurs losses. We estimate the model using returns, options, and inventory and find that it performs well, especially during the financial crisis. The restrictions imposed by nested existing reduced-form stochastic-volatility models are strongly rejected in favor of the model with a market maker.

In this paper, we investigated the risk averse ness of KOSPI 200 option investors with very flexible risk preference structure. Contrary to the most of previous research either assuming a time-invariant underlying asset return distribution or assuming a well-known functional form for the underlying utility functions. we directly assume functional forms for Investors’risk aversion functions. With the direct specification on the risk aversion functions themselves. we can avoid the possibility 이 suffering from Internal inconsistency and of obtaining misleading risk aversion functions. From our empirical results using KOSPI 200 Index option prices from 1997 through 2006. we discovered that the investors' relative risk aversions exhibit ‘sharply decreasing' across wealth. In addition, our Implied subjective PDFs are found to more accurately forecast the distribution of realization than both the risk neutral PDFs and implied subjective PDFs from previous methods. For the robustness of our empirical results, we test the effects of estimation errors In the expected risk premium, and of financial crisis in the late of 1990s.
