Almost that many traded today....there’s nothing like a good short squeeze! LOL
I’d bet that a BUNCH of shorts were covered tuesday or even monday by the insiders, institutions (ahem!), and savvy traders. Look at the last 30 minutes volume spike on tuesday......and keep open to the idea that a bunch covered at $45 over the day or two previous without much of a blip in volume. Just the chumps got bought in starting wed am....
