This is a tough one to figure. On pace for the highest volume day in 6+ months. There have not been 3 million share days in a row in a long time. I doubt the short number drops below 3m so maybe 10% of this volume is short covering. So what's the rest? Tres Amigos contracts? Maybe, Law suit good news? Highly doubtful but a possibility. Good qtrly's coming? I doubt that., AMSC would announce that before they let insider trading go on for a few days. Feels like a big contract brewing or some other moderately good news.
