E-mini index futures are an excellent way to either hedge long portfolios or simply trade to make a buck. Capital requirements are very low. Risk/reward is not hard to figure out, liquidity is excellent, and of course, you can easily trade in either direction. Short below 1320. We'll continue to get temporary lows (one coming soon), but nothing to trade on the long side for more than a week. I'm not at my home computer. I'll post some numbers later when I get home. Look here for contract specifications for the S&P e-mini:
