Possibly. Definitely an attempt to steal it at a low level imho. I think SLG is easily worth $1.10 with financing in place. It will be interesting to see if we open at .83 or much higher.
Please don't fall for the tree shaking games in pre-trade or at the open. If you plan to sell into this bid, at least do yourself a favour and wait for the end of the day to do it. At worst, the stock doesn't top the bid price and closes within a few percent of the bid. At best, it surges much higher.
My two bits worth of advice for all current SLG longs.
