Markets In Focus: The Week That Was and What’s On Tap Week-Ending 7/17/2026
THE WEEK THAT WAS
US equity markets posted their first losing week in three, with the weight falling squarely on AI-linked names rather than reflecting any broad deterioration in fundamentals. The S&P 500 declined 1.6% on the week, while the Nasdaq Composite bore the brunt of the selling, falling 2.9%. The Russell 2000, by contrast, held up considerably better, slipping just 0.5% a divergence that tells you more about this week’s story than almost any other data point.
The week began with genuine optimism. Q2 earnings season opened with key releases from JPMorgan, Goldman Sachs, Bank of America, Wells Fargo, and Citigroup on Tuesday morning, arriving alongside the June CPI report, and for one brief moment the market had everything it needed. The CPI fell a seasonally adjusted 0.4% for the month, bringing the annual inflation rate down to 3.5%, well below the Dow Jones consensus estimate of 3.8%, and the banks broadly confirmed an economy, and consumer, operating with continued resilience. It looked, for about 48 hours, like the trifecta investors had been waiting for.
Then Friday arrived. When Chinese AI startup Moonshot unveiled its Kimi K3 model, AI and semiconductor stocks dropped sharply as traders drew immediate comparisons to the so-called DeepSeek moment of 2025, when a Chinese lab released a model that performed comparably to US rivals at a fraction of the cost. The Philadelphia Stock Exchange Semiconductor Index fell 1.6%, widening its drawdown from a June record to 20%, meeting the technical definition of a bear market.
What the Russell 2000’s relative resilience confirms is that this was not a macro selloff. Small caps have no meaningful exposure to the AI infrastructure trade, and they barely moved. The damage was concentrated in the same crowded names that have carried the market higher all year, and the question heading into next week is whether TSMC’s 77% earnings growth and ASML’s raised guidance matter more than a single Chinese model release. History says it should.
THE WEEK AHEAD
This is shaping up to be the week that tests the market’s patience with the AI spending story. Alphabet reports Wednesday after the close, and the real question isn’t the ad business, it’s whether hyperscaler capex guidance still justifies the semiconductor and power infrastructure trade that’s carried so much of this year’s return. Tesla reports the same evening, with the usual focus on margins and whatever the autonomy narrative demands this quarter. Intel follows Thursday, offering a useful, if imperfect, gauge of foundry progress against a competitive landscape still dominated by Nvidia. IBM rounds out the tech read on enterprise AI adoption.
ServiceNow also reports Wednesday, and this one deserves attention beyond the usual software checklist. The stock is still working through the hangover from its April guide-down on subscription gross margin, and management has leaned hard into the AI narrative since, talking up Now Assist and its broader “AI control tower” positioning along with the Armis integration. The market will want to see actual monetization, not just adoption metrics, given how much scrutiny AI software names are under right now to prove the spend translates into durable revenue rather than just a good story on the call.
Away from tech, the calendar is genuinely full. Lockheed, RTX and Honeywell report against the backdrop of the Farnborough Airshow, which should keep defense order commentary in the headlines through Thursday. Union Pacific and Norfolk Southern give a freight and industrial demand signal, while Comcast and T-Mobile round out the consumer and telecom picture.
Macro data is comparatively light but not irrelevant. Jobless claims, the Chicago Fed activity index and the Kansas City Fed’s manufacturing survey all land midweek, but Friday’s flash PMIs are the number that matters most, particularly on the services side. All of this falls inside the Fed’s blackout window ahead of the July 29 meeting, so there’s no policy commentary to lean on. With that quiet, earnings alone will set the tone, and the AI software names have as much riding on this week as the chip and hyperscaler complex.
