Weekly recap

Week of October 12, 2026 | Weekly Market Recap

The S&P 500 fell about 1.9% and the Nasdaq Composite about 4.5% for the week, while the Dow Jones Industrial Average gained about 0.7%. A sell-off in chip and AI-infrastructure stocks, worries about how that buildout is financed and hotter inflation data drove the split.

How the week ended

Stocks slid on Friday, October 16, with technology shares leading the decline. The S&P 500 closed at 7,659.44, down 1.09% on the day; the Dow Jones Industrial Average closed at 52,002.41, down 0.34%; and the Nasdaq Composite closed at 26,140.03, down 2.14% (first prints at about 4:18 pm ET, preliminary) [1]. The VIX, a measure of expected stock-market swings, rose to 20.16 [1].

For the full week, measured against the October 9 closes, the S&P 500 fell about 1.9% (from 7,811.54), the Nasdaq Composite fell about 4.5% (from 27,366.17) and the Dow rose about 0.7% (from 51,654.95) [10]. The PHLX semiconductor index fell about 11.4% over the same five sessions, from 12,572.42 to 11,137.29 [10]. A chip-led rotation therefore left the broadest tech-heavy gauge far weaker than the price-weighted Dow.

Friday's losers were concentrated in AI data-center and chip names. Shares of AMD and of a British chip-design licensor were each down about 5% in the afternoon after a Delaware jury found the licensor breached a license agreement with a U.S. chipmaker [8], and Broadcom and another chip company each fell about 4% after Broadcom chief executive Hock Tan warned that a shortage of capital could become a limit on AI spending [9].

Elsewhere, the 10-year Treasury yield ended the week near 5.10%, down from about 5.24% a week earlier [1][10]. West Texas Intermediate crude, the U.S. oil benchmark, settled near $98.96 a barrel, up about 7.7% from $91.85 on October 9, and Brent crude finished near $109.67, up about 4.7% from $104.72 [10].

Inflation, yields and the Fed

Monday, October 12, was quiet: the S&P 500 slipped 0.06% to 7,807.24, the Dow rose 0.38% and the Nasdaq Composite fell 0.44% [10]. On Tuesday, the Nasdaq lost 0.15% and the S&P 500 0.02% as chip stocks extended recent losses and investors weighed mixed results from big banks; reports that a Chinese memory-chip maker had made technical advances added to worries about competition for U.S. suppliers [2].

Wednesday brought the week's sharpest move. The September rose 0.6% from August and 3.7% from a year earlier, up from 3.4% in August; core prices, which leave out food and energy, rose 0.3% on the month and 2.6% on the year, a little above forecasts [4]. Higher gasoline prices were cited as a main driver [4]. The S&P 500 fell 1.10% to 7,719 and the Nasdaq Composite fell 1.88%, its first drop of that size since late July, as technology was the weakest sector [4]. That report also said the data made a Federal Reserve rate increase a more open question [4].

On Thursday, the producer price index, which tracks prices businesses receive, rose 1.3% in September from August against a 0.5% consensus forecast, a midday market summary reported [11], and the Census Bureau reported retail and food-services sales of $745.0 billion in September, up 0.8% from August and 6.3% from a year earlier [5]. Even so, Treasury prices rose as investors sought safety, and the 10-year yield fell to 5.09% from 5.19% [3]. That yield had topped 5.30% earlier in October and reached its highest level since 2002 [3]. The Dow gained 1.08% to 52,177.69, the S&P 500 rose 0.33% to 7,744.06 and the Nasdaq Composite edged up 0.08% to 26,713.03 [3].

On Friday, the Federal Reserve reported that industrial production rose 0.7% in September after a 0.1% gain in August, with manufacturing up 0.3%, mining up 0.2% and utilities up 3.5%; capacity utilization rose to 76.9% [6].

Chip stocks and earnings

A sell-off in AI-related shares began on Wall Street on Wednesday and spread abroad. South Korea's Kospi, which is dominated by Samsung Electronics and SK Hynix, fell 7.6% on Thursday and Japan's Nikkei 225 fell 4.9%, before U.S. stocks steadied [3]. The Kospi has dropped 39% since its June record [3]. The worry, as AAP described it, is that data centers and AI chips are expensive and many companies borrowed to pay for them, while yields at multi-year highs make borrowing costlier and make investors less willing to pay high prices for stocks [3]. Shares of a heavily indebted AI cloud-computing provider fell 15.5% on Wednesday and rose 5.9% on Thursday [1][3].

Big-bank earnings opened the week. On Tuesday, Citigroup fell 5.6% and Goldman Sachs 0.2% even though both beat profit estimates, Wells Fargo fell 3.1% after its missed estimates, and JPMorgan Chase fell 0.9% after what AAP called a rare profit miss [2]. Shares of Bank of America, Citigroup, Wells Fargo and State Street were reported lower after results by Wednesday's close [4].

Regional-bank results arrived Friday. Truist reported third-quarter earnings of $0.56 a share, or $1.16 a share excluding items, up 12% from a year earlier on that adjusted basis; the gap reflects a loan sale and a securities repositioning, and on October 14 the company agreed to sell $7.7 billion of unsecured consumer loans, substantially all of its LightStream platform, to Carlyle Group [7]. Adjusted figures are company-defined, non-GAAP measures. On Thursday, BNY rose 3.2% on better-than-expected profit and a large insurance broker rose 4.6% [3]. This summary did not verify Friday results from Regions, Citizens Financial Group or M&T Bank Corporation, or how bank shares traded on Friday.

What remains uncertain

Friday's closing figures are first prints taken from Yahoo Finance at about 4:18 pm ET and may be revised. Another 24/7 Wall St. page showed slightly different Friday readings (S&P 500 -1.08% to 7,664.30, Dow -0.45%, Nasdaq 100 -2.30%) that appear to be from an earlier snapshot; this recap uses the Yahoo close. Weekly changes were calculated from Yahoo Finance daily closes for October 9 and 16, and oil figures are front-month futures, which can differ from other benchmarks. The producer-price figures come from a market summary rather than the government release. The Friday trading in bank shares, other Friday regional-bank results and the cause of the Friday afternoon moves in individual stocks were not confirmed from primary sources. The Wednesday report's reference to a possible Fed rate increase is one outlet's reading, not an official signal. Some company moves (AMD, Broadcom and the other chip companies named) were intraday and may have ended the session differently.
