ptsc had a positive markman and their stock declined after...so there is no exact science at work here. They got some good news regarding future prospects for their patents.
I am happy for them that shareholders are now back in focus and buying the stock at these low levels in anticipation for future results. So far it's a game of confidence.
The market is ready to make a buck on companies that hold promise, penny stock or blue chip, and when that light shines on EDIG the company will present a healthy profile with much promise.
What exactly will trigger the market to take notice remains to be seen, but that investment phenomenon is in play in today's markets as there are few other conduits for capital generation outside of the stock market currently.
