13F tape: rotation over beta
Macro was the same cautious soup—sticky inflation, higher-for-longer, nothing new. The action came from disclosures and manager-level shifts, not some big index shove. Flows were lumpy, and positioning did more work than “risk-on/risk-off.”
Q1 snapshots from the filings:
- Appaloosa sold Delta (DAL), American, and United, while buying Amazon and Uber. A clean move out of cost-sensitive transport and into platform names with operating leverage.
- Bridgewater exited Salesforce and cut PayPal. More unwinding of prior-cycle “quality + fintech.”
- Soros Fund Management added Nvidia and Apple, and bought Berkshire Hathaway. Stay with megacap momentum, add cash-flow ballast.
- Amicus Therapeutics caught a bid after John Paulson disclosed a new position; Paulson also closed SOLS.
Bottom line: the market can feel defensive and still throw sharp, single-name demand at whatever fits the right mandate. “Buy the index” isn’t the whole story when concentration is this high.
Airlines: buyer vs seller
Airlines were the cleanest case study in disagreement.
DAL traded up after Berkshire Hathaway disclosed a new $2.6–$2.8B stake. The size is the headline, but the context is the signal: Berkshire famously bailed on airlines in 2020 under Buffett. This is the re-entry, reported under Greg Abel. It reads as either renewed confidence in the industry’s structure or a very specific vote for Delta’s execution.
The other memo came from Appaloosa, which exited DAL/American/United in Q1. That’s a reminder the margin stack is still one shock away from being rearranged—fuel, labor, demand volatility, pick your poison.
And there’s a real-world datapoint the market keeps pulling into the model: Flix North America’s CEO pointed to rising bus demand due to high fuel costs. It’s a simple comment, but it matters. When fuel bites, behavior shifts, and airlines don’t get to opt out of that substitution.
Takeaway: the group stays headline- and input-sensitive. A marquee buyer helps the tape, but it doesn’t hand the sector an all-clear.
AI capex: incentives and “down the stack”
The cleanest fundamental catalyst was Meta, up on news it’s set to receive $3.3B in Louisiana tax breaks tied to a $10B data-center project. Incentives don’t change the physics, but they do change the math: cheaper capex, smoother permitting, and a higher chance the build stays on schedule. The tape treated it as a green light on buildout cadence.
That fit with the day’s AI infrastructure drift:
- Ongoing attention on data centers and optical/photonics as second-derivative AI exposure.
- A Photonics ETF showing significant recent inflows, consistent with investors pushing beyond the obvious compute winners into interconnect, networking, and optics.
Rates can still be a grind, but the AI capex complex remains one of the few places capital shows up, commits, and keeps paying.
What mattered today
- 13Fs drove the action: concentrated, mandate-driven flows outweighed broad beta.
- Airlines are a live split:Berkshire buying DAL versus hedge-fund exits, with fuel still the swing variable.
- AI buildout stayed bid:Meta’s $3.3B incentive and optics/data-center positioning kept demand firm.
- Story stocks still trade on message discipline:MSTR sold off after CEO Phong Le emphasized value “beyond financial assets.” In that name, clarity is the product.
Today wasn’t about macro magic—it was about who owned what, who stopped owning it, and where the next check is getting written.
