DD - Every stock is "manipulated" by it's MM's.... that's just how the game is played.  They claim they are creating an "orderly" market, while the retail investor and little guy claims foul.  This happens in almost every stock to a greater or lesser degree, depending on external factors, uncertainties, company financials, news, etc.  If you are confident in what you own then whatever shenanigans the MM's may pull should not dissuade you (or anyone) from ownership.  In the markets, all is not always how it appears.   What is important is thorough DD and a little bit of luck mixed in.

Cheers.
