Shorts are now really underwater. It seems as though between December and January the shorts added one million shares. It looks as though most of them happened at 108 and 106. When market opens they will be at least $10 under water. That is quite costly. Will there be a short covering over the next few days. Especially with all the upgrades. Not a lot of volume on the weekly options here so I don't think there will be much price control going into Friday. This may go up just on a small short covering.
Possible but maybe not. Stock did not spike until AH yesterday. Trade desk use the previous days close to figure margin calls if any. shorts will have until tomorrow until they are forced to cover IMHO.
