just stocks going into russell 1000 2000 3000 and microcaps, from what i learned i like to trade stocks that are going to be added only if they have been trending down and vice versa for the shorts because it seems they like to bring em down before they rip em. if a stock has been ripping for days into the russell chances are they will squeeze you down and print lower on the close. price action has been scrwey last few years so if you take this approach the risk reward is better.
