United States Daily Briefing

Micron Technology posted Q3 2026 earnings with revenue quadrupling as memory prices surged from an acute supply crunch driven by AI data center demand. The 10% stock surge following a 700% trailing 12-month gain underscores how extreme the memory chip pricing cycle has become — Micron is reprinting the playbook from the 2021 DRAM boom, but this time driven by HBM chip demand for AI accelerators rather than consumer electronics. Tomorrow's key watch: Samsung and SK Hynix reaction in Seoul — if Kospi semis extend today's recovery into the Micron print, the AI infrastructure thesis holds.

The Federal Reserve confirmed all large US banks passed the 2026 annual stress test — positioned to lend through a severe recession scenario. The macro signal is straightforward: the banking system is not fragile. Yet insider activity data shows 27 Form 4 sales totaling 74M versus just 3 buys at 3.7M in the past 72 hours — a 71:1 sell-to-buy ratio that screams distribution at the top. Fairmount Funds offloaded 99.7M of SYRE alone. The stress test is a rearview mirror; insider selling is a forward signal, and right now insiders are voting with their feet.

Wednesday's session was less about market direction and more about what's rotating. Home Depot +5.7% to $342.86 and Thermo Fisher Scientific +4.9% to $492.20 led S&P gains — both defensive/consumer names with real earnings underpinning the move, not momentum. Mastercard +1.3% and Visa +1.1% extended their run on payments resilience. The read: growth/momentum factor is losing ground to value/defensive; MTUM likely underperformed SPLV today. This is not panic — VIX flat tells you that — but it's deliberate positioning heading into the weekend with Darden Restaurants (DRI) Q4 earnings due Thursday morning.
