Never heard that theory before. You mean cops and fireman coming home from work move the market? And I always thought it was mostly institutions who do pre and after trading. Not to mention the 3 million shares traded during the day. You must know more than I.
More like analysts and PMs will do work over the weekend and realize that eteplirsen appears to be a real drug. If eteplirsen works then anyone wanting exposure to biotech stocks should own it. And let's hope it is approved early for the kiddos. But if not - and you think the drug works - the stock is still a buy with 12-18 month time horizon. With the 74 week data showing consistent efficacy and safety, I believe many investment companies not already on board will start buying at these levels.
