i've only shorted twice in my life, no longer than a day each time.
i'm averse to shorting stock even though it would've been the best strategy over the past year (i.e. pick any stock, practically, and short it)!
i'm all in cash now. my prediction is selling will beget more selling and we'll see a precipitous DROP very soon. valuations are still high under a recession scenario. and with a u.s. "super committee" achieving absolutely nothing we're bound to re-test the lows from 2 months ago and go LOWER. so cash for now.
