Almost every day I see a post from someone saying how they are going to stop trading equities and make the shift to index futures. The reasons cited include, new shorting rules, exchange misconduct, PDT, lack of volatility, and so on. So my question is, if a significant number of traders move to NQ or ES then (perhaps?) the volatility of individual stocks will be reduced. But since index movements are based on equity values, would index futures not become equally untradeable? Anyone?
