It's a Friday and that means fun, easy segments with lots of energy. Well, CNBC delivered today when they asked me to talk about 13Fs from the big dogs in the business, Buffet, Tepper, Burry. A 13F is just a regulatory filing to show the SEC what you owned on the last day of the quarter, so it becomes public about 6 weeks later. So, nobody knows when they bought or sold something or even if they still have it - so you take it with a grain of salt.

We talked about NVDA and chips in general having the issue not simply with valuation - but the risks of getting chips to markets from the foundries. Then we breezed through Expedia (competing against the credit card points economy), CVS (Marc Cubans is competing for the high profit, somewhat evil pharmacy benefits management business), and I had good things to say about housing going forward and DHI is the leader there.

My point is to dig deep when looking at individual stocks. Don't just buy something because a big hedge fund or Warren buffet bought it. Holdings on a single day, revealed six weeks later is just a list of stocks that could have some potential.
