When the people running a company start selling their own stock in size, the rest of us should probably pay attention.
Right now, the insider buy/sell ratio across American public companies has crashed to 0.24 — meaning executives are buying just $0.24 of stock for every $1 they sell. That’s one of the lowest readings on record, and well below the long-term average of 0.40. In plain English: the people closest to the numbers are heading for the exits while markets hover near all-time highs.
The selling is particularly aggressive in AI data center stocks. At Oracle, the CEO sold 10,000 shares on the open market, the president dumped 15,000 shares and gifted another 5,000, and a director offloaded 2,223 shares — all beyond their regular pre-approved selling plans. At CoreWeave, the pace is even more alarming. The Chief Development Officer has sold nearly 1 million shares, the Chief Strategy Officer roughly 770,000, and the CEO about 300,000. Many of these sales happened immediately after shares were awarded — a historically bearish pattern that signals executives view their own stock as something to flip rather than hold.
There’s a fundamental problem brewing beneath the surface of the data center boom. Cloud computing producer prices have been slipping from their summer peak, according to the Bureau of Labor Statistics. Microsoft’s Intelligent Cloud costs rose 10.1% sequentially last quarter while revenues grew only 6.5%. Amazon Web Services reported similar margin compression. That suggests AI computing is starting to face pricing pressure — bad news for companies like Oracle and CoreWeave that have bet billions on future demand at today’s premium prices. Nvidia’s $500 billion backlog (22 months of sales) means these companies are locked into chip commitments at steep prices with no guarantee their own customers will pay up when delivery comes.
But it’s not just tech insiders running. Delta Air Lines executives unloaded an unusual amount of stock in the past week: the EVP of Global Sales sold 38,600 shares, the president dumped 302,000, the Chief External Affairs Officer sold 27,000, and the EVP of International offloaded 35,000. Delta’s shares had surged 84% since last April’s Liberation Day selloff and now trade at the upper end of their historic range at roughly 10x forward earnings — the same level that preceded a 20% decline in 2022-2023.
The airline selling is particularly notable because it aligns with deteriorating consumer data. Existing home sales crashed 8.4% in January. Inventory of unsold homes rose to 3.7 months. Eight out of 13 retail categories posted December declines, with big-ticket items like autos and furniture leading the weakness. When Delta insiders sell, they’ve historically been right — including well-timed exits before both the 2024 correction and the pre-Covid demand sag in 2019. The signal is clear: the smart money closest to the action isn’t waiting around to see if the economy holds up.
