I can tell you one thing. I don't short too many stocks, but I am taking pleasure in shorting KCG. I look forward to their demise and will love to kick them while they are down. NITE are the biggest criminal scumbags in the whole business. They have naked shorted every penny stock around. I love shorting KCG it feels so right !
