RE: thecat777Dusty,
I'm sorry but I must disagree with your "regulators doing their job" theory. The first reason is that not only has there been worst trading scenarios with other stocks that could have triggered halts, but there has also been worst scenarios with this stock, in both directions.
However the real clue was the reason for the halt as posted by the regulators. "Pending news" was their reason, and as we all now know, we did get news that same day. However the news was about a halt. which couldn't be the news that cause the halt because the halt hasn't happened yet for the news to be news. Do you follow? Therefore something is fishy here which is a reason why many posters have been debating the issue in their own form.
Once the Endo news is finally released, we might be able to figure some of it out. But there is still a chance that we may never know for sure what or why this really happened.
