In my view that kind of fund managers are unlikely to change their view. Based on his statement, he doesn't understand those companies at all. If he can't understand Tesla, Netflix, BMW in the first place, he won't understand them later. I think his fund will be wiped out at some point.
To give you an extreme example, if a company holds 100 ton of gold, meanwhile the company does some gold mining, made a little bit of money by the year end because the mining activity was very costly, P/E is 200. This manager would view that as very expensive. They were taught a P/E of 10~15 is more appropriate. Netflix has large amount of content that people will continue to pay $10 a month to subscribe, and they are ready to expend into china. Their subscription could double to $20B a year. They also could monetize on these 200 million subscribers in the future, in addition to the monthly fee... Not saying NFLX is a good buy now, I'm saying that manager doesn't know what he is doing.
Edit: the manager talked about Netflix P/E is 200. Does he understand that's because Netflix is using all the revenue to produce more content, which is the right thing to do. He should have shorted Amazon in the past, because Amazon never had good earnings.
