Just caught something interesting in the latest 13F filings that dropped Feb 17. A bunch of heavyweight billionaire investors basically dumped their Meta positions in Q4 — we're talking about seven major fund managers offloading stakes. Laffont, Mandel, Druckenmiller, Smith, Loeb, Coleman, Halvorsen — all paring back or completely exiting their Meta holdings.

Sure, Meta was up roughly 50% between April and October, so profit-taking makes sense on the surface. But here's what's got people thinking deeper: Zuckerberg just announced another capex increase tied to the AI Superintelligence Lab. The worry is that heavy spending on AI infrastructure could pressure near-term earnings, even if the long-term play makes sense. These billionaires clearly have concerns beyond just locking in gains.

What's wild is that many of these same investors who dumped Meta are simultaneously piling into Taiwan Semiconductor Manufacturing. Laffont bought 556k shares, Halvorsen grabbed 970k, Tepper added 70k. TSMC is now Mandel's top holding too. These guys are clearly betting that the AI chip demand story is where the real opportunity sits right now. TSMC's got the supply constraints working in their favor — massive backlog, serious pricing power on AI chips. Plus they've got the smartphone and IoT segments providing steady cash flow underneath it all.

The signal here is pretty clear: billionaires are dumping the big social platforms and rotating hard into semiconductor infrastructure plays. Whether that's the right call long-term, we'll see, but the money is definitely moving.
