Certain stocks are more hype driven than anything. Tesla, Apple, Netflix etc... A couple of bad things happen and watch the stock fall pretty fast, a couple of good things happen and watch the stock rise up really fast. I think for some of these companies stocks don't really measure anything other than hype. Beyond Meat is a good example, stock price went crazy cause "revolutionary meatless concept", started from $40 dollars and went to like $200 bucks in a month or two, now hype has died down, its back down to $80. It is still a solid company judging by their earnings report but people have now lost faith because the hype died down.
