It's because they don't post garbage all over internet chat boards like a lot of other hollow stocks. There is still probably a lack of awareness from investors. There are a few stocks like that. Those are usually the ones that hit huge if you are patient enough. I don't put much into stocks that have these absurd trading volumes. While you can hit a big profit at times on those, they usually plummet at some point and stay stuck for a long time.
From what I can tell, they are spending their time getting contract after contract instead of hyping their stuff up on the internet. Ultimately, money talks and b.s. walks. If you're making money, the stock will go up. I suspect what they make off of these labs they will use for other parts of their business and grow that.
I mean, when you look at some of these CEO's on these chat boards they look like idiots. You're a CEO. Act like it.
