Investors reacted strongly to the downside on news of the latest trial results, while the companies headline read more bullish.
Going to look at this one as potentially oversold - time will tell of course.
Could look at a stop limit buy order where if the stock recovers then you can enter the trade, but if it continues to head down then you stay out. Would also suggest of course a stop loss as well.
Might be one for the watch list to do more research around if you like this kind of potentially oversold on news type play.
