Prior Session Recap — Monday, September 14, 2026

Monday partially reversed Friday's relief rally. The Dow closed down roughly 0.48%, the S&P 500 fell 0.78% to 7,597.83, and the Nasdaq dropped 1.09% — a broad risk-off session concentrated in tech and semis. Your YM data (H 53090 / L 52642 / Settle 52861) shows a 448-point range on the day. The trigger was a weekend AI-safety scare: Anthropic's CEO called for a temporary slowdown in frontier AI development, and a researcher's resignation letter warning that AI leaders "earnestly believe it could kill us all by the end of the decade" rattled chip and AI-infrastructure names. The Philadelphia Semiconductor Index fell roughly 5%, with Nvidia down 3.4%, Broadcom down 4.8%, Micron down 5.2%, and Lam Research down 8.3%. Compounding the tech rotation, the 10-year Treasury yield briefly crossed 5% for the first time since 2023, and oil pushed back toward $110/barrel after talks with GCC states over tanker flows were rejected — reviving the energy-driven inflation concern that had pressured markets the prior week.

Fundamental Picture

The market enters today's session at the center of the FOMC meeting, which runs today and concludes tomorrow (Wednesday) with the rate decision — markets are pricing a very high probability of a 25-basis-point hike. That puts this session in a classic pre-decision holding pattern: expect positioning to stay cautious and headline-driven rather than trend-committed, with participants reluctant to build large directional exposure ahead of tomorrow's announcement and press conference. The AI-infrastructure selloff adds a second live thread — whether Monday's weakness in chips and hyperscalers was a one-day sentiment reaction to the AI-safety comments, or the start of a broader reassessment of AI capex valuations, will likely show up in whether semis stabilize or extend losses today.

Layered on top of the Fed decision is the energy/yield dynamic that has driven the last two weeks: oil approaching $110 on stalled Strait-of-Hormuz-adjacent diplomacy, and the 10-year yield's break above 5% both argue for a market that's sensitive to any further escalation. A rate hike that comes with hawkish forward guidance, combined with sustained $100+ oil, is the scenario most likely to pressure the Dow further; a hike accompanied by any dovish signal on the pace of future tightening — or a pullback in oil — is the setup most likely to spark another relief bounce like Friday's.

Trade Ideas (2 With-Trend / 1 Counter-Trend)

With-trend #1 — Pivot rejection short: With price below the pivot (52,864), a failed retest of the pivot from below with 15-min MA confirmation offers a short toward S1 (52,639), consistent with the two-day pattern of below-pivot opens.

With-trend #2 — S1 breakdown continuation: If S1 (52,639) fails to hold — particularly on further semis weakness or an oil/Middle East headline — look for continuation short toward S2 (52,416).

Counter-trend — Pivot reclaim long: A reclaim and hold above the pivot (52,864) with 15-min bullish MA alignment offers the counter-trend long toward R1 (53,087), on the thesis that semis stabilize and positioning turns constructive ahead of tomorrow's Fed decision.
