Tuesday, Sep 1, 2026, then tomorrow
All four major indices closed lower, with the Nasdaq (NDAQ) 100 leading declines at -1.26% and the S&P 500 down -0.68% to 761.63. The catalyst was clear: US forces struck Iranian targets near the Strait of Hormuz, driving WTI crude up 5.4% to $90.38, pushing the 10-year Treasury yield to 4.80% (highest since January 2025), and triggering inflation/rate-hike repricing. Fed Chair Warsh's hawkish remarks lifted the odds of a Fed rate hike to 68%, hammering high-multiple software names including CrowdStrike (CRWD), Palo Alto Networks (PANW), and Axon (AXON). Breadth was 4/11 sectors positive, with defensive rotation into Energy (+1.33%), Utilities (+0.84%), and Health Care (+0.64%) while Consumer Discretionary (-1.73%) and Technology (-1.45%) led losses. VIX jumped 1.42 points to 16.34, its highest in this recent band. The geopolitical premium in crude, the 4.80% 10-year, and the 68% rate-hike odds all carry directly into tomorrow.

What drove it (and may carry over)
Curated from the day's market wire.
Wednesday, Sep 2, 2026
What is scheduled, with ET times. Not a forecast of how it lands.
There are no scheduled economic releases for Wednesday, Sep 2. The dominant structural forces are Broadcom (AVGO) and Snowflake (SNOW) earnings after the close (~4:05 PM ET), which will concentrate volatility in semiconductors and cloud names in the after-hours session. Watch the 10-year yield and crude for continuation or stabilization of today's geopolitical bid: any escalation or de-escalation near the Strait of Hormuz will move both. The Jobs report lands Friday, Sep 4 at 8:30 AM ET, meaning Wednesday and Thursday carry pre-payrolls positioning risk that tends to suppress risk appetite in rate-sensitive names.
Reporting tomorrow, and we have a view
What in the report would support or undermine our published research.
Confirms: AI networking and custom-silicon revenue growth alongside stable or expanding operating margin above 49% would validate the franchise quality thesis.
Breaks: Operating margin falling toward or below 42%, or free-cash-flow margin contracting toward 30%, would signal deteriorating demand from hyperscalers.
