Example of Suntech Short Coverer

Alpha Vulture:

"I also exited my short in Suntech, and this is something I should have done a few months earlier because at the current low price of the stock the carrying costs of the position are a bit too much (despite the fact that I was synthetically short using a structured product instead of having to borrow shares). The short position returned 56.4% in a bit more than a year time, a result I’m happy with since the leverage of the position was less than one."

This is why the short interest keeps falling.
