Oil Crashes on Iran Truce, Chip Rout Caps Broader Rally Ahead of Fed and Mega-Cap Earnings
The US paused its airstrike campaign against Iran, leading to a sharp drop in crude oil. However, a selloff in semiconductor stocks erased the early relief, leaving major indexes mixed as the market braces for the Fed decision and earnings from four Magnificent Seven companies.

The S&P 500 is torn between a tailwind from falling oil prices, which eases cost pressures, and a headwind from tech weakness, given the index's heavy weighting in technology and communication services. The Fed decision and mega-cap earnings will determine the near-term direction.
Markets ended mixed as a sharp drop in crude oil and a semiconductor selloff offset a relief rally from the US-Iran ceasefire, with the spotlight on Fed policy and mega-cap earnings.

Bond Markets Price Elevated Chance of Fed Rate Hike This Week

A surprise rate hike would be a headwind for equities by tightening financial conditions, particularly for growth and technology stocks that are sensitive to higher discount rates. The Fed's decision could shift the S&P 500's near-term trajectory.

These four companies are among the largest weights in the S&P 500. Their earnings outcomes and guidance will heavily influence index-level returns, especially given elevated valuations and the ongoing debate about AI capex sustainability.

Higher borrowing costs and deteriorating free cash flow for mega-cap tech could pressure valuations and reduce the earnings power of the largest S&P 500 constituents, which are key drivers of index performance.
Nvidia's Role as AI Financier Sparks Dot-Com Comparisons
NVDA · SPXNvidia is reportedly negotiating financing guarantees to backstop OpenAI's data-center buildout and investing in an AI startup. Market commentators draw parallels to the dot-com era, as Nvidia's financing strategy introduces balance-sheet risk.
As the largest semiconductor company and a key S&P 500 component, Nvidia's stock is sensitive to changes in investor perception of its financial risk. Any weakness could weigh on the technology sector and the broader index.
Semiconductor Selloff Erases Early Gains, Nasdaq Underperforms

Semiconductors are a critical subsector of the S&P 500, and a sustained rout could drag down the broader index, especially given the high correlation with other tech and AI-related names.
Oil Prices Crash as US Pauses Iran Strikes, Easing Supply Fears

Lower oil prices reduce input costs for many S&P 500 companies and support consumer spending, benefiting sectors like transportation, industrials, and consumer discretionary. However, energy sector losses may partially offset the gains.
