Crude Oil Volatility: Hedgers or Investors

We evaluate differential effects of the trading activity of two classes of traders: hedgers and general investors, on the volatility of the NYMEX crude oil futures returns. It appears that the rebalancing activity of oil hedgers has a significant and positive effect on the oil futures volatility. On the other hand, non-commercial players (investors) who take positions in the crude oil futures as well as stocks and bonds do not affect the crude oil volatility significantly by rebalancing their positions.Crude Oil Futures Volatility, Optimal Portfolio Weight, Hedge Ratio, GARCH, Time-Series, Effects of Investors and Hedgers
