The U.S.-led strike on Iraq bucked world equity markets last week with equity derivatives players, including hedge funds and prop traders, benefiting from war positions that have been held for several weeks. Everyone has been expecting a big war rally and from a pure directional point of view traders have been playing the upside, buying calls and selling puts, noted one trader at a New York-based dealer. Equity option volatility declined in conjunction with the equity market rise. The Chicago Board Options Exchange's volatility index (VIX), which measures the implied volatility of 30-day index options, fell to 34.46%, last Thursday, having traded at 37.32% the Monday before the attack, and as high as 40% in January, in anticipation of war. Equity option volatility typically travels in an inverse direction to equity performance, he noted.
