Institutional Shorts Buying Back IMHOSupport on the shareprice comes from both Long Positions being opened and Short Positions Covering (buying back).
IMHO those institutions have a lot of shares to buy back / cover on and they are going to pop the price on the smaller shorts so that they can further cover using the margin calls.
Here's a Quote for everyone to keep in mind...
"Bears win Battles... Bulls Win WARs"
Its a big reason why you should consider extended time periods when investing.
