Day trading pre-market open July 22, page-119

I'm Just a newbie, but I would assume that this a prime example of someone trying to pump a stock? As it was clear from last nights performance on the NASDAQ, IMRN opened at over $20 (after pre market) and finished down at $14.81 ... This to me would indicate IMC will be finishing somewhere today in the 50-60's ... But please ignore me if I am wrong ... I am a few day old newbie hehehe
