U.S. equities pushed higher Monday even as the conflict between Washington and Tehran deepened, with investors turning their focus to a heavyweight week of technology earnings. The S&P 500 gained 0.63%, the Nasdaq Composite climbed 1.02%, and the Dow Jones Industrial Average added 0.23%, while the small-cap Russell 2000 slipped 0.42%.
Geopolitics Sets an Uneasy Backdrop
The gains came against a tense geopolitical backdrop. The United States conducted a new round of airstrikes against Iran over the weekend, and the Pentagon announced the death of another American service member, bringing the weekend toll to at least three U.S. troops killed in Iranian retaliation, according to TheStreet's Monday market coverage.
Oil markets remained the clearest transmission channel. Brent crude climbed back above $90 a barrel as fighting continued, though prices eased from session highs after Iran's foreign ministry said diplomatic efforts were still underway. Yahoo Finance reported that mediators have delivered proposals to Tehran about resuming direct negotiations with the U.S., a development that appeared to embolden dip buyers in risk assets even as headlines stayed grim.
Big Tech Takes the Spotlight
The main event for the tape, however, is earnings. TipRanks noted that 77 S&P 500 companies are scheduled to post second-quarter results this week, headlined by Alphabet, Tesla and Intel — a trio representing well over $5 trillion in combined market value that will all report within roughly 48 hours of each other.
Per CNBC's earnings playbook, Tesla is set to report after Tuesday's close, with its analyst call slated for 5:30 p.m. ET. The EV maker's earnings are forecast to have grown 25% from the year-earlier period, according to LSEG estimates. Alphabet is scheduled to release results after the bell Wednesday, followed by a call at 4:30 p.m. ET. IBM is also on this week's slate after a bruising 25% single-session drop earlier in the month tied to its AI shift.
Wall Street has been raising expectations across the AI complex. As Forbes columnist Bill Stone summarized in his weekly preview, investors are watching for evidence that hyperscalers are beginning to monetize AI at a scale that justifies the massive capital-expenditure ramp of the past 18 months.
The "Magnificent Seven" Framing Under Fire
Not everyone is convinced the old megacap grouping still tells the story. In a note flagged by Yahoo Finance, Citigroup analysts argued that the "Magnificent Seven" — Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia and Tesla — is "no longer relevant" as a way to assess exposure to the U.S. AI trade, pointing to the widening dispersion between AI infrastructure winners and the group's laggards. The Roundhill Magnificent Seven ETF (MAGS), which offers equal-weight exposure to the cohort, edged up 0.14% to $67 in premarket trading.
What to Watch
With Brent above $90, U.S. troops in the line of fire, and roughly a fifth of the S&P 500 reporting this week, the market is threading a narrow path. The setup leaves little room for a soft print from Alphabet or Tesla — and even less for an oil-driven inflation surprise ahead of the Federal Reserve's next policy decision.
