Futures Trading and Equity Market Volatility
This article examines the relationship between trading demand by the type of traders in the S&P 500 index futures market and the volatility of the underlying asset using the CFTCs COT data that give futures positions of categorized traders.The trading demand is proxied by the net futures position.We find that after controlling for the effect of the overall trading activities,the equity market volatility is negatively associated with signed demand shocks of speculators,but positively related to the signed hedging demand shocks.Consistent with the portfolio insurance hypothesis that the actions of portfolio insurers result in distinct demand-volatility relationships across trader types,our results suggest that the hedging activities rather than the speculative futures trading have a destabilizing effect on the stock market.
