$尚德电力(STP)$ At November 15, Suntech short interest was 12 million shares. By the end of the year 2013, 5.6 million of those had covered leaving 6.4 million short.

That was 29 trading days which means 193,000 per day were being covered.Volume during that time period was averaging about 0.75mm shares per day, of which short covering has apparently been an appreciable fraction.

It almost looks as though someone impatient has decided to cover their short at 50 cents, and their bid is fueling their impatience because it is propping the price up.
