They’re a very well run company with a shit ton of innovation, but the investments into it are running high on speculation, same as Tesla. There’s great opportunity in it, but also great risk as investors are banking on NVDA being the lone elephant in the AI room. One company comes out with something better? Look out…
Buffett looks at the people running the company, absolutely, but more so he looks at the product they produce and how he understands it. Take Apple, he didn’t touch it until his assistant lost her iPhone and he realized through her reaction how significant it is today. That’s the one tech stock he’s heavily invested into. Financials, insurance, oil, and common products; that’s what he knows and buys.
Buffett not investing into something is hardly a reason to not buy into it, he would be the first to agree with that. And I say that with BRK.B being the lone single stock I own.
