The 5 Wildest Moves From Q4 2025's $53 Trillion 13F Filing Season

The February 14 deadline has passed. Over 8,500 institutional managers have filed their Q4 2025 13F disclosures with the SEC, revealing $53.3 trillion in holdings. After digging through the data, here are the five most jaw-dropping moves that tell the story of where smart money is heading in 2026.

1. Renaissance Technologies Nuked 85% of Its NVIDIA Position

The world's most famous quant fund didn't just trim NVIDIA — they demolished it. Renaissance cut their position from $1.05 billion (5.63M shares) to just $163 million (871K shares). That's $888 million in NVIDIA exposure gone in 90 days.

But here's what makes it truly wild: they simultaneously went +2,545% into Netflix, +5,221% into Costco, and opened a brand-new $206M Amazon stake. Oh, and they completely exited Meta.

This wasn't routine rebalancing. After October's "Quant Quake" — where RIEF plunged 14.39% and RIDA cratered 15.6% — this looks like an emergency rebuild of factor exposures.

2. Bridgewater's $4.8 Billion SPY Bet — A 10x Position Increase

Dalio's team went from $480 million in SPY to $4.82 billion in a single quarter. An 883% increase. That one ETF position is now larger than their next 20 holdings combined.

Meanwhile, they exited 168 positions and initiated 86 new ones — rotating nearly a third of the entire portfolio.

3. Buffett's Apple Selling Finally Stops — at Exactly 300 Million Shares

5. The Great Divergence

Renaissance is dumping NVIDIA while others pile in. Burry went all-in on China. Bridgewater went full S&P. Ackman made a contrarian Nike bet. The smart money has never been less unanimous.
