Just noticed something interesting about how the world's richest hedge fund managers approach stock splits. Most of us think stock splits are just a retail investor thing to make shares more affordable, but these billionaires? They're playing a different game entirely.

I dug into the latest holdings of the top 10 richest hedge fund managers - we're talking Ken Griffin at Citadel with $37.7B, David Tepper running Appaloosa at $20.6B, Steve Cohen's Point72 sitting at $19.8B, and others in that tier. These aren't people worried about share prices being too high. Yet they're clearly paying attention to which stocks are splitting.

What caught me was how consistent their choices are. When you look at their portfolios, a few names keep popping up. Chipotle made waves with that massive 50-for-1 split back in mid-2024. Broadcom's 10-for-1 split also showed up across multiple billionaire portfolios. Walmart's 3-for-1 split in early 2024 was another favorite, especially for Bridgewater's Ray Dalio.

But here's what really stood out - Nvidia absolutely dominated. The richest hedge fund managers all seem to have Nvidia as either their top or second-biggest position among stock-split plays. That 10-for-1 split in June 2024 was the sixth in Nvidia's history, and it's clearly resonating with serious money. Ken Griffin, David Tepper, Ray Dalio, Israel Englander, David Shaw - they're all holding it. Steve Cohen's Point72 has it as their second-largest split position.

Now here's where it gets interesting. Some of these same billionaires actually reduced their Nvidia positions in early 2024. Griffin, Tepper, Englander, Shaw - they were trimming. That's a reminder that just because the richest hedge fund managers own something doesn't mean it's a guaranteed move.

The reality is, Nvidia's valuation already reflects pretty serious growth expectations. Whether you think that's justified depends on whether you believe the Blackwell architecture rollout will exceed expectations. I'm genuinely uncertain, which is probably the most honest take.

One thing I'd agree with every billionaire hedge fund manager on though - the stock split itself? That's already history. Don't let the split mechanics influence your actual investment decision. The fundamentals are what matter.
