Tech Drags Markets Lower as Traders Position for Nvidia Results and Iran Sanctions
The Dow Jones Industrial Average rose 0.28% on Monday, August 24, 2026, while the S&P 500 fell 0.18% and the Nasdaq fell 0.38%, with technology stocks again pressuring the index. Reuters
MSCI's global equities gauge was lower, as weakness in technology stocks offset support from a dip in U.S. Treasury yields and falling oil prices. Reuters The split performance, with the Dow outperforming while growth-heavy indices lagged, is the latest expression of a rotation pattern that has intensified through the summer as semiconductor valuations have come under sustained pressure.
The selloff in chip stocks has been building in waves. On June 5, 2026, a global chip selloff erased more than $1 trillion in stock market value, hitting AI heavyweights including Nvidia. Reuters By late July, the Philadelphia Semiconductor Index (SOX) had extended its losses, falling 2.2% in a single session and sitting 21% below its record high close on June 22, 2026, though still up 63% year-to-date. Reuters In that same late-July rout, chip stocks shed approximately $1 trillion in market value, with Nvidia, SK Hynix, and TSMC each losing more than $100 billion. Nvidia alone saw a $238 billion decline in market capitalization. CNBC
The selling has not been confined to semiconductors. On Tuesday, August 18, 2026, broader technology stocks sold off alongside rising bond yields, with the Dow falling 0.22%, the S&P 500 down 0.69%, and the Nasdaq dropping 1.33%. Reuters U.S. stock index futures were stable on August 19 following that tech-driven slide, but the respite proved narrow. Reuters
Two catalysts now frame the near-term tape. Markets are awaiting Nvidia (NVDA.O) results, with the AI giant expected to be a key driver of market direction. Reuters That earnings print lands against a backdrop where geopolitical risk continues to seep into the pricing of rates, crude, and risk appetite. U.S. Bank reported that the Iran conflict and the Russia-Ukraine war continued to shape global markets through oil prices, shipping routes, trade policy, and inflation in 2026. U.S. Bank
The Nvidia result carries particular weight given the stock's role as the bellwether for the AI capex cycle. A $238 billion single-session rout in the name in late July, followed by the broader $1 trillion wipeout across chip stocks, means positioning into the print is likely polarized. Bulls can point to the SOX still being up 63% on the year; bears can point to the 21% drawdown from the June 22 high and the fact that two separate trillion-dollar selloffs have hit the sector in under three months.
The cross-asset picture adds another layer. Falling Treasury yields and declining oil prices on August 24 would ordinarily be tailwinds for duration-sensitive growth equities. That they failed to offset tech weakness suggests the selling in semiconductors and AI-leveraged names is idiosyncratic to the sector's earnings and valuation dynamics rather than a pure macro risk-off move. The Dow's positive close, driven by its lower tech weighting, reinforces that read.
What remains unresolved is whether Nvidia's results can arrest the drawdown or confirm it. The stock has been the single largest contributor to both the AI rally and its unwind. With the SOX in correction territory and two major catalysts, earnings and Iran sanctions, arriving in the same window, realized volatility across the semiconductor complex is the base case rather than the outlier.
