Munger Mode rating: 2 out of 5 — Sell. Our own rating from the research report below, on business quality first: moat durability and management, with price separating the top three.
We have looked hard at this business, and we want to say up front: this is not an easy "no." Marvell is growing revenue at a rate most companies would kill for, it sits inside the most talked-about capital expenditure cycle in the history of computing, and the people running it have made some clever strategic moves. But being exciting is not the same thing as being a wonderful business, and a fast-growing company can still be a poor investment if you have to pay a price that assumes everything goes right for a decade. That is roughly the situation here. We will walk through our reasoning the way we always do — business first, people second, numbers third, price last — and we will end up somewhere less enthusiastic than the stock's recent chart would suggest.
