My memory is bad but, wasn't there a theory on here a long time ago that the zombie stocks were very successful short attacks. Those companies went under and rather than close that position collecting all that profit from 100s of millions of shorts that are now HUGELY profitable, they keep the position open to dodge taxes. The positions are not profit on the books yet. They close them when capitol is needed to balance losses and remain profit neutral.

So if this theory is true, the split dividend caused big losses on their end, so they close their successful short positions on dead companies. Collect the profit and use it to offset GME losses and stay alive one more day.

This is pure speculative theory based on pieces of other theories lol.
