After weeks of treading water, U.S. stock futures found their footing Tuesday morning — and they brought two unlikely dance partners to the floor: stronger-than-expected corporate earnings, and the faint flicker of a ceasefire between the U.S. and Iran.
The S&P 500 and Nasdaq Composite have been essentially flat for weeks, held down by the triple headwind of rising oil prices, the U.S.-Iran conflict, and a fresh wave of Chinese AI models rattling tech sentiment. Tuesday offered a reprieve on all three fronts.
The Numbers
- Nasdaq 100 futures jumped 1.4% as chip stocks roared back to life. The VanEck Semiconductor ETF surged more than 3% before the opening bell, with Marvell Technology up 7%, Micron Technology gaining 6%, and Intel adding more than 5% — reclaiming the $100 mark.

- S&P 500 futures added 0.6%, while Dow futures advanced 169 points (0.3%). The moves reversed Monday’s losses, when rising oil prices dragged the major averages lower. (Source: Quartz, July 21)
- Earnings are delivering. With roughly 54 S&P 500 companies having reported second-quarter results, 87% have cleared profit expectations — a beat rate that’s giving fundamental ballast to the rally. 3M surged more than 7% on stronger-than-expected earnings, while General Motors added 2%.

- Brent crude pulled back from the $90 threshold overnight after mediators proposed a 10-day ceasefire between the U.S. and Iran. Brent had touched $90.95 — its highest level in this cycle — as the two sides exchanged strikes for a 10th straight day. The diplomacy news took some heat out of the energy trade.

What’s Moving the Needle
This rally isn’t being driven by one catalyst — it’s a rare convergence of three things breaking the right way at once.
First, the earnings story. The 87% beat rate isn’t just a feel-good number — it’s evidence that Corporate America is navigating the higher-rate, higher-oil environment better than the market priced in. 3M’s blowout quarter (the stock jumped 7%) and GM’s profit beat are industrial bellwethers that matter. This week brings the heavy hitters: Alphabet, IBM, and Tesla all report.
Second, the ceasefire diplomacy. Pakistan-mediated talks have produced a 10-day ceasefire proposal, and for the first time in nearly two weeks, the diplomatic needle is pointing toward de-escalation rather than deeper conflict. Oil’s retreat from $90 tells you markets are taking the talks seriously — at least for now. The conflict has been a persistent tax on equity sentiment since April.
Third — and this is the part nobody’s talking about — South Korea and Taiwan just posted export data that confirms the AI chip story isn’t a bubble narrative. According to Bloomberg, both countries reported strong July export numbers driven by AI-related semiconductor demand. When the physical supply chain prints numbers like that, it validates the equity story in a way that analyst upgrades never can.
Ahead of the midterms, after the earnings season, in a month, month and a half, I think that’s probably the time where you want to take a little bit of your foot off the gas.

The Bottom Line
Tuesday’s rally is built on a fragile two-legged stool: earnings are carrying the fundamental case, and ceasefire hopes are carrying the sentiment case. Both are real — but both can wobble. The earnings beats so far are encouraging, but the biggest names report later this week. And ceasefire proposals have been made, and broken, multiple times since this conflict began in April.
For now, though, markets are taking the win. After weeks of flat performance while absorbing geopolitical shock after geopolitical shock, a day where the news actually gets better — on multiple fronts — feels like genuine relief. Enjoy it. But keep one eye on Brent and one eye on Alphabet.
What to watch Wednesday: Existing home sales data, plus the latest round of S&P 500 earnings. Alphabet and Tesla are the headliners later in the week.
