I'm not totally clear on margin accounts, but it just occurred to me that if your $TSLA shorts were backed by other stocks that tanked then you might be forced to cover simply because the others were going down -- which would tend to push $TSLA up and might explain the final >4% lead over NASDAQ.
Well, I don't know, but its a thought.
Yah, if your longs are down and your shorts are up, it's wedgie time...
(not a nice squeeze)
Oh well, shut the thread down till Thursday, no Market till then...
