You are right…there is no conspiracy. It was just bad luck/or good luck for some depending if you are one of those who shorted the stock. But remember these headlines from a few months ago.
ARIAD PHARMACEUTICALS STOCK SEES SHORT INTEREST JUMP 14%
The most recent short interest data has been released by the NASDAQ for the 07/31/2013 settlement date, which shows a 2,230,507 share increase in total short interest for ARIAD Pharmaceuticals, Inc. (NASD: ARIA), to 18,217,590, an increase of 13.95% since 07/15/2013.
This was the same time Goldman Sachs was accumulating their millions of shares with a neutral rating and a projected price of 21. My gut is telling me that for every share GS bought, they also shorted the stock one share. Think about this, if you buy a share for $19PPS and also short it for $19, then you do not lose anything if you create a new market at $5.75 a share. What you need is a lot of shares to keep the stock price down!!!
