A concentrated chip selloff drags the headline indexes down even as most stocks rise
U.S. stocks fell for a second straight session Friday as a deepening semiconductor selloff outweighed genuinely broad earnings strength. The S&P 500 dropped 0.5% (37.85 points) to close at 7,533.77, the Nasdaq Composite fell a sharper 1.5% (387.28 points) to 25,881.95 given its heavier chip weighting, and the Dow Jones Industrial Average slipped a more modest 0.2% (105.32 points) to 52,553.32. The headline decline masked real strength underneath: eight of the S&P 500's 11 sectors closed higher and roughly three of every four individual constituents ended the day up, but a small handful of heavily-weighted semiconductor names were large enough to pull the cap-weighted index lower on their own. The VIX rose 6.8% to 16.73, while trading volume came in light at roughly 17.19 billion shares, below the 20-day average of 21.19 billion.
Chip stocks enter a bear market as Moonshot's Kimi K3 model sharpens AI-competition fears
The PHLX Semiconductor Index tumbled more than 3% Friday, pushing the sector into bear-market territory — down over 20% from its June highs — part of a rolling selloff that has erased roughly $3.3 trillion in chip-sector market value since June 22. Memory-chip makers Micron, Samsung and SK Hynix are each down more than 20% from recent highs. Adding pressure Friday, Chinese AI startup Moonshot released Kimi K3, a 2.8-trillion-parameter open-source AI model it says is the largest of its kind, intensifying investor worry that Chinese competitors are closing the gap with U.S. AI leaders and could compress returns on the hundreds of billions of dollars U.S. companies are pouring into AI infrastructure. Not every chip name suffered equally: Nvidia, trading just under $200, is roughly flat over the entire stretch and remains the best-performing large-cap semiconductor stock in the group, though still down 17% from its May record.
Netflix crashes 9% after hours, then reverses the entire move to close higher
Netflix supplied Friday's single wildest stock move. Shares sank as much as 9% in after-hours trading Thursday and extended that slide into Friday's premarket after the company guided third-quarter revenue to $12.86 billion and earnings to $0.82 a share, both below Wall Street's $13 billion and $0.84 estimates; the guidance implies revenue growth slowing to 11.7% — its weakest pace since late 2023 — down from 16.2% in the first quarter and 13.4% in the second. Netflix also said it would scale back the viewership data it discloses, feeding concern that its growth advantage has peaked. Yet the stock reversed sharply through the session, touching an intraday low of $72.94 before rallying to close up 0.91% at $74.35 — a round trip of roughly 10 percentage points from its after-hours low near $67.62.
Earnings mostly beat, but the market only rewarded some of them
Second-quarter earnings were otherwise a bright spot. UnitedHealth Group beat estimates by $1.44 a share ($6.38 vs. $4.94 expected) and its stock rose 1.2%. Abbott Laboratories beat by 3 cents ($1.31 vs. $1.28) and jumped 10.7%, while J.B. Hunt Transport beat by 20 cents ($1.91 vs. $1.71) and gained 8%. Not every beat was rewarded: GE Aerospace beat estimates and raised guidance for the second time this year but still fell 4.1%, and Johnson & Johnson beat estimates yet fell 2.7% on a miss in its medtech device sales. Separately, a Philadelphia Fed factory gauge for July jumped to 41.1 from June's 10.3, another data point suggesting the industrial economy remains resilient even as Wall Street frets over chip valuations.
Iran war escalates further, oil holds near $80, and consumer sentiment ticks up as yields ease
The Iran war that began February 28 escalated further this week: Iran struck a water desalination plant in Kuwait and hit targets in Qatar, Jordan and Iraq's Kurdish region, killing at least eight people, in an expansion of attacks against U.S. allies in the Gulf. WTI crude held above $79 a barrel — around $79.65 — on track for a weekly gain of more than 11%. The 10-year Treasury yield fell more than 4 basis points to 4.525% Friday as investors weighed the conflict against encouraging domestic data, including cooler producer and consumer price readings this week and jobless claims that came in below forecast. A preliminary July consumer-sentiment reading from the University of Michigan showed confidence up roughly 10% from May as gasoline prices moderated and year-ahead inflation expectations eased to 4.6% from 4.8%, even though sentiment remains about 13% below its level just before the war began in February.
Concept of the Day
Market Breadth
Market breadth measures how many individual stocks are actually participating in a market's move, rather than just looking at the headline index number. The most common breadth gauges are the advance/decline count (how many stocks rose versus fell) and sector counts, and they matter because major U.S. indexes like the S&P 500 and Nasdaq are cap-weighted: a handful of the largest companies can move the index far more than hundreds of smaller ones combined. When breadth is strong even as the index falls — or weak even as the index rises — it's usually a sign that a small number of mega-cap stocks are driving the headline number rather than the market as a whole. Friday's session was a textbook example. The S&P 500 fell 0.5%, which on its own sounds like a broadly negative day for stocks. But eight of the index's 11 sectors actually closed higher, and roughly three out of every four individual stocks in the index ended the day in the green. The entire net decline came from a small group of heavily-weighted semiconductor stocks — a sector that makes up more than a fifth of the S&P 500's total value — falling hard enough to drag the cap-weighted average down despite most of the market rising. Breadth divergences like this are worth tracking because they function as an early signal. A narrow rally, where the index rises but breadth is weak, has historically been a more fragile advance than one where gains are broad-based, because it depends on a small number of stocks continuing to perform. Conversely, a day like Friday — where breadth is strong but a concentrated sector drags the headline number down — suggests the damage is more contained to a specific theme, here AI-chip valuations, than a broad loss of investor confidence in equities generally.
Why it matters
Today's breadth split is exactly the kind of signal that determines whether Friday's decline should worry a portfolio manager. Because the loss traced almost entirely to a concentrated semiconductor selloff rather than a broad flight from equities, it argues for treating this as a sector-specific valuation reset in AI-related chips — sharpened today by Moonshot's Kimi K3 release — rather than a signal to de-risk across the board. Anyone checking 'how bad was today' should look past the index number to how many stocks actually participated before drawing conclusions.
What to Watch

The weekly claims report is the most current read on layoffs, worth watching after this week's claims data came in below forecast.
Tue, Jul 28
FOMC meeting begins (rate decision July 29)
The Fed's next rate decision lands with cooling inflation and firm jobless-claims data pulling one way and elevated oil prices from the Iran war pulling the other.
Fri, Jul 31
University of Michigan Consumer Sentiment (Final, July)
This final read will confirm whether the preliminary rebound in household confidence held up as gas prices eased and the Iran war continued.
Mon, Aug 3
ISM Manufacturing PMI (July)
This will show whether factories are absorbing higher input costs from elevated oil prices, coming right after a strong Philly Fed factory reading this week.
Wed, Aug 12
CPI (July)
The next consumer inflation reading will show whether the recent disinflation trend held up through a month of elevated oil prices tied to the Iran war.
