Did you notice that institutional investors have bought more than 100% of the float? And how exactly can these long-term value investors buy more than 100% of the available stock?

How can the shorts ever buy enough shares to cover? There's only one way, and that's to drive the price so high that the long-term investors decide to cut their holding below 100%.
