Technology sold off hard while the Dow held a gain: oil surged on deepening Gulf disruption, a solid 30-year auction pulled yields back from 24-year highs, and the AI complex bore the brunt of the de-rating.

The Dow gained 0.10% while the Nasdaq fell 1.25%—a rotation, not a uniform risk-off session.
Brent rose 4.1% to $104.28 as tanker attacks, thinner Hormuz flows and absent Iranian loadings tightened the risk picture.
The 30-year auction drew a 2.54 bid-to-cover ratio versus a 2.41 average, pulling the long bond back from 5.732%.
The day’s cross-asset message was unusually clean: long bonds rallied, oil jumped, defensives and energy held up, and the most valuation-sensitive AI infrastructure names sold off.
The close’s essential market drivers, distilled from WSJ, Barron’s, MarketWatch and FT reporting.
A tanker was struck north of Qatar after 10 tankers were hit from Sept. 28 to Oct. 4. Hormuz flows fell and Iran loaded no crude in September. Brent closed at $104.28; Aramco’s CEO called global buffers “scarily thin,” while the U.S. strategic reserve sits at 283 million barrels, its lowest since 1982.
FY2026’s deficit topped 6% of GDP and was the highest nominal shortfall ever. Interest now consumes more than $1 of every $5 of tax revenue as publicly held debt crosses 100% of GDP.
The 30-year auction passed its confidence test with a 2.54 bid-to-cover ratio versus a 2.41 average. The 30-year yield ended near 5.61% after touching a 24-year intraday high of 5.732%.
The S&P 500 forward multiple has compressed to 19.3× from 22.2× at the year’s start. Since the Aug. 13 high, 18 of 25 industry groups are down. Q3 earnings begin next week.

The 30-year fixed rate reached its highest level in nearly three years. Twenty-one percent of sellers cut asking prices, while demand for adjustable-rate mortgages hit a four-year high.

Canada shows the mirror image of the same rotation: crypto miners HUT.TO, HIVE.TO and DMGI.V fell together, while IPCO.TO and OBE.TO rode the oil spike. FTG.TO’s 25.9% beat-driven jump on 5.6× volume and CMG’s 6.1% M&A-driven gain on 3.5× volume were the two clearest idiosyncratic standouts.
