It's possible there may be a small/early correction in the recent run up purely due to the confusion but I expect the overall effect to be nil. I don't see anything here that reflects badly on Impax or changes its fundamentals in any way. Someone in the media made a mistake and it went into the echo chamber. This is a well positioned company with good prospects and the chart shows this stock as having been under accumulation for months -- long before this particular media foot-in-mouth. That said, it does have risks and you should make sure you understand these risks as well as the upside potential. Their recent JP Morgan presentation would be a good starting point for getting management's story on its company.
