Stock markets, having spent much of the week recovering from an earlier dip to finish Thursday on a broadly positive note, slipped back into the red when trading resumed Friday morning. Shares in the technology sector pulled the Nasdaq — an index weighted heavily toward tech companies — to a one-month closing low.

By the close of trading, the Nasdaq had shed 572.99 points — a 2.1 percent retreat that left the index at 26,140.03, though it had recovered somewhat from the steepest losses recorded during the session. Broader losses weighed on the S&P 500, which gave up 84.62 points — a 1.1 percent retreat — to settle at 7,659.44, whereas the Dow's pullback proved considerably shallower, trimming just 175.28 points, or 0.3 percent, to close at 52,002.41.

Over the five-day trading period, the Nasdaq shed 4.5 percent of its value and the S&P 500 gave back 2 percent, while the Dow managed a 0.7 percent advance.

Technology stocks faced another round of selling pressure, pulling the Nasdaq lower as investors weighed unease over borrowing-driven outlays on artificial intelligence infrastructure. Hardware stocks tied to computer equipment ranked among the weakest performers in the technology sector, as the NYSE Arca Computer Hardware Index shed 5.4 percent on the day to settle at its lowest closing level in two months, continuing a stretch of losses that has built up over recent weeks. Declines in semiconductor, networking, and software stocks added to the pressure bearing down on the Nasdaq, pulling the index lower across the session.

Airline shares bore the brunt of a sustained climb in crude oil prices, pulling the NYSE Arca Airline Index down 3.2 percent — a drop that stood apart from broader activity in the tech sector. Shares in brokerage and biotechnology companies retreated, whereas crude oil's upward move lifted energy-sector stocks in tandem.

West Texas Intermediate crude climbed back through the $100-per-barrel threshold for the first time in four weeks, driven by a renewed round of Iranian activity in the Strait of Hormuz and the breakdown of what had been described as an energy truce between Russia and Ukraine.

Federal Reserve data for September pointed to domestic industrial output climbing at a pace that outpaced analysts' forecasts. Data from the Federal Reserve showed a 0.7 percent gain in industrial output for September, building on a modest 0.1 percent advance recorded in August after that earlier figure was revised. Forecasters had pencilled in a 0.4 percent gain for industrial output, against a prior month that had come in flat when first tallied.

Equity markets spanning the Asia-Pacific zone ended the week on a broadly upbeat note, with most bourses posting gains when Friday's session wrapped up. Trading in Tokyo lifted the Nikkei 225 by 1.4 percent, while the Hang Seng in Hong Kong posted a more modest gain of 0.5 percent. Equity benchmarks across the continent's leading exchanges all posted gains by the close.

Gains of 1 percent for the German DAX, 0.4 percent for the UK's FTSE 100, and 0.3 percent for France's CAC 40 left all three European benchmarks in positive territory.

Treasury yields drifted without a clear trend in the wake of the preceding week's gains. Trading at 5.075 percent, the ten-year benchmark note's yield has edged lower by 1.2 basis points.
