You are thinking that ACB is really a $10 Stock that is trading for $1.90.
But the other side is: ACB is really a $1.90 Stock that was trading at $10 because of hype. And once the hype wore off - it went back to $1.90.
A "Game Changing Catalyst" could be a lot of things. It could be an awesome PR that announces a huge deal. Or it could be a fantastic Earnings Report that blows all Forecasts out of the water. Or it could be something we haven't though of yet.
I understand the 30 Day Rule for Tax Selling. However, I really don't think ACB is going to jump on February 1st because Tax Sellers are eager to get back in after losing their money and realizing losses. But I could be wrong. We'll see.
