I don't think the allegations do much downside for this stock. The last few waves down probably had less to do with accusations of so-and-so and more to do with the stock's high P/E (present and forward) and overall market weakness. I am bearish on this stock in the near term because I don't think they will show solid growth in earnings in the upcoming July release. I also think the stock is overpriced and should be trading in the mid to low 70's.
Having said that the stock is very heavily shorted and one trying to short this can get steam rolled if not careful or stubborn. It squeezes hard on light volume. I believe it is actually the short position on the stock that is propping it up. The market has to fool most of the people most of the time.
