It's a new rule for Pension brokers. It's pretty stupid and does nothing but give brokers more $ with separate tickets.
As for your explanation, yes folks playing OTC stocks take that chance buying them in the first place. They should already know that most OTC/pink stocks only run on news for a couple days because most have no real value to the market. That's how OTC/pinks work. That's nothing new of course.
I'm the opposite. I daytrade big boards for security and hold a couple pennies long wherever they may end up. OTC/PINKs are all gambles in my opinion. They're just for fun, I put little $ in them.
