Bought a headset to play fortnite and figured a ton of other people were probably doing the same.  It think this is basically the easiest investment strategy.  Just observe a trend that an older investor probably wouldn't understand and then buy something so that you can capitalize.  I bet there weren't many analysts/investors that realized so many people would buy headsets to play fortnite.

This reminds me of that king of the hill episode, a bill full of dollars.
