Just dug into something interesting about how the world's richest hedge fund managers actually position their portfolios. You'd think billionaires would be immune to stock splits since they can obviously afford any price point, but there's a pattern here worth noting.

I pulled the latest data on the top 10 richest hedge fund managers - we're talking Ken Griffin at Citadel leading with $37.7 billion, followed by David Tepper, Steve Cohen, and the usual suspects in the ultra-wealthy investor space. What caught my attention was their shared conviction around one particular stock that went through a split.

They all seem to have the same favorite: Nvidia. This isn't some random coincidence. Griffin, Tepper, Dalio over at Bridgewater, Englander at Millennium Management, Shaw - they've all made Nvidia their largest position among split-adjusted holdings. Cohen's Point72 ranked it second. The company executed a 10-for-1 split back in June 2024, and apparently that move signaled something these billionaires wanted to be part of.

There were other contenders in the mix. Chipotle pulled off a monster 50-for-1 split and showed up in multiple portfolios. Broadcom did a 10-for-1 split and caught Cohen's attention as his top position. Walmart's 3-for-1 split made appearances too. But none of them had the concentration that Nvidia commanded across these richest hedge fund managers' holdings.

Here's what's weird though - some of these same billionaires actually reduced their Nvidia positions in early 2024. Griffin, Tepper, Englander, Shaw all trimmed exposure. So they're not blindly holding. That's the real lesson here. The stock split itself doesn't matter to people with unlimited capital. What matters is the underlying business and whether growth prospects justify the valuation.

With Nvidia, there's legitimate debate. Some think the AI boom is already priced in. Others see the Blackwell chip architecture launch potentially exceeding expectations. The richest hedge fund managers in the space seem to be threading that needle - maintaining exposure but not going all-in.

Bottom line: if you're watching how billionaire investors move, Nvidia's a case study in conviction without dogma. They like it, but they're not married to it. That's probably a smarter framework than chasing stock splits for the sake of affordability.
