First of all, remember this is an "investigation" not a lawsuit. These things happen all the time, only a very small percentage ever lead to a lawsuit.
Secondly, let them investigate...they will not find anything. The company has only proposed things for shareholder vote. If the shareholders agree and vote something to occur, then it's extremely difficult if not impossible to sue.
Third, I have been trading an investing in stocks of all sizes over my career. Quite frankly, this is one of the best opportunities I have ever been a part of. Needless to say, I continue to add on any weakness. Our day is coming.
