Buffet is a great investor, no doubt, but he does not understand tech very well. The data doesn't lie. As the internet has grown in past 10-15 years, Buffet has not adapted. Talk about being late to the Apple party (and arguably early on selling this quarter).
The reason I did this graph is because my father in law (probably most fathers / father in laws) loves Buffet and a good friend of mine is a data scientist for a hedge fund who just DCA (Dollar Cost Average) buys the QQQ and nothing else.
Disclosure: I own neither but majority of my portfolio is 40% Tesla and 50% Crypto (Bitcoin and Ethereum and 10% alt coins), and 10% apple,msft, genomics, pltr and a few others.
