"Most of these class action lawsuits get settled for the BOD and CEO's Errors and Omissions insurance policies. It is a distraction for the executives and also not good for the shareholders." But does not damage the company.
Wait and see what happens in the morning. This is not selling normally in AH. It shows bid at 6.27 and ask at 6.34 yet someone just bought 260,328 at $6.42. Lots of shares purchased after hours all around $6.42. If this goes up in the morning then you will see a reverse head and shoulders pattern. There is no reason for this sell off. Nothing but good news. Average down but if it runs up sell off some so you maintain the 4000 shares you want to own. The stock fluctuates between 20 and 30 cents a day. Good trading.
