I believe there was some insider selling. Looks like about 18k yesterday and who knows how many others that knew about it . Would have been nice to see it hold for awhile above $40 but with all the supply comming just wasn't enough demand. I own and have since $8+ and have bought more on every secondary and will still do so. Didn't like what I saw yesterday though.
I own the stock and like it, but it has been very parabolic the last few weeks and is pretty far away from it's 50 day moving average and MACD and RSI appear to be topping and pointing down- in the near term i think this stock could hit 33-35 (won't be a popular view on here) and the stock is also more of a defensive play, with the dow moving to new highs, folks are chasing higher beta and more volatile stocks that are likely to both rise and drop more quickly
