As I said in an earlier post, what a broken stock means to me is one where the company's value, earnings and prospects no longer correlate with the stock price. I think most investors like to think of a stock's price as the "truth" about a company. It should reflect all that is known about a company. However, I think if you beat a stock savagely enough, you can uncouple the stock price from the company it represents. Then, changes in the price of the stock no longer reflect the "truth" about a company and become meaningless. A good analogy would be water-boarding prisoners. After water-boarding a prisoner a couple of hundred times, there is no "truth" to the words coming out of the prisoners mouth.
I'm surprised this didn't reverse or flatten today due to OE, which is what typically happens to stocks making large moves. But this stock doesn't behave like any other stock so why should I be surprised?
