It doesn't matter if they are kids, smart or dumb. They are a retail shareholder force.
There are 194,000 Robinhood members holding GNUS shares. If, they average a little more than 750 shares each, they could easily handle all outstanding shares of GNUS.
If they all decide to dump GNUS, the share price would plummet. And, if a lot more decided to buy in (almost a million own Ford), it could easily take the share price well above the highs.
It would be wise to keep track of what they do.
