Lately, I've been running into companies I didn't even know had publicly traded stocks like $WISH, $GPRO or $DUOL. $WISH and $GPRO have a very similar chart, the stock shot up in the beginning, but then quickly fell again and hasn't risen since. But I quite like $DUOL as I see potential here and I think people will use this app even more and so their stock could go up. I recommend you check out @lukasandel who wrote an interesting status/article on Duolingo about a month or so ago.
How do you view these stocks and have any companies surprised you by having publicly traded stocks?
