If institutional investors want to buy some MSTX put up 30mil shares for sale yesterday with an ATM. I don't see them stepping up to the plate yet. But who knows.
Simply because they own enough shares to run it up and sell at $3/share. Right now they are probably just day trading it. They will probably buy calls for chump change first, run it to $3, then swap calls for puts in volume, then sell and quietly exit.
