I bought a Fidelity over-the-counter mutual fund years ago that was composed entirely of over the counter stocks, and Fidelity is a large, well known brokerage. It is not unusual for institutions to buy over-the-counter stocks.
Regardless of the CEO's level of credibility, it is clear that the sell off occurred based upon something other than this company's fundamentals. It could have simply been a panic sell off by individuals for all I know, but at this point, it is clear that this stock has been over sold and is selling for a bargain price.
