When it happened I thought it was either manipulation or someone knew something about GM being saved this weekend. That was some volume. People are saying window dressing, I'm not that familiar with how that works in the market. I do get that managers do not want their books to show they missed this rally, but all at once? They had all day to buy, not sure.
As far as a short cover, it did double bottom for the day and then push past an early morning high. Also the 914 level. But that volume... who is short that heavy? And are they hiring? They have a lot of money to burn in a sideways market.
If GM is saved I will understand it, if not I hope someone figures it out.
