Quote from Daal:
It' the hottest new business model right now, short the stock put a negative report and cover into weakness
A lot of the times it pays to buy along with the short seller into the squeeze but sometimes you want to short even though he is covering because the news will be just too shocking and other sellers will come out. I'm learning more and more on how to trade this situations
Yeah it really does depend on the individual situation.
If you look at NEPT (Seeking Alpha) although it is up 18% today, it fell by a lot after the publication of the article.
I doubt (and I could be very wrong) that what Ackman says tomorrow will move the stock by much. He will (as Zero Hedge point out) likely just reiterate the thesis put forward by David Einhorn.
Late-to-the-party shorts will open positions. Bottom-fishers and shorts lacking conviction will buy. I agree that the weakness in HLF was noticeable since Friday's close. And as I mentioned above, it broke below 42.15 just hours before the report came out.
