I'm no expert, but from what I've concluded from Vgrinshpun's very helpful (thanks) Fidelity reports is that shares borrowed are not necessarily shares shorted. For instance someone can borrow and pay interest on 100,000 shares, and then either hold them or sell them over time as they see fit. Alternatively someone could return 400,000 shares all at once, like today, but in fact those shares may have been bought over the past week. Is this true? I don't see any other way to make sense of the large sudden changes in shares available to short at Fidelity. The advantage for the short seller in using this method would be that, while paying extra interest, nobody would know exactly when they are doing the shorting or covering.
