TWEED is now top dog, and because of the sector and the fact they have what half of these mj companies want, $5 -$10, is coming you watch! This is normal employee/management/early investors cashing out some of their deserved shares. Watch the bounce next week!
You never want to be too careful as part of being an investor is following your gut and taking a few risks but then you need to be careful not to be too cautious. All stocks opening day start high some keep going up and some go down.
