Global equity markets, especially those with a significant technology component, saw declines on Thursday, July 16, 2026, driven by a widespread sell-off in chip stocks. This happened even as Taiwanese chip manufacturing giant TSMC reported higher-than-expected earnings growth of 77%. Gene Goldman, chief investment officer at Cetera, commented that the "AI trade isn't being priced on growth anymore. It's being priced on perfection. Any earnings report that's merely great, instead of flawless, gets sold." The Philadelphia semiconductor index sank more than 4%, marking its second consecutive day of losses.
The Dow Jones Industrial Average rose initially but closed lower, while the S&P 500 fell by 0.51% to 7,533.77, and the Nasdaq Composite dropped 1.47% to 25,881.95. Memory-chip makers, including SanDisk, Western Digital, Seagate Technology, Intel, and Micron Technology, were among the biggest decliners, with shares falling between 4.8% and 12.6%. The technology sector in the S&P 500 fell 1.8%, with the 4.3% drop in semiconductor stocks heavily influencing the overall market. Paul Nolte, senior wealth adviser at Murphy & Sylvest, highlighted the increased weight of chip stocks in the S&P 500, now over 20% compared to 8% a few years ago.
Despite the chip sector's weakness, some positive economic indicators were released. US retail sales increased marginally by 0.2% in June, aligning with economist expectations, and jobless claims dropped, along with surging manufacturing activity in the northeast. UnitedHealth Group's stock gained 1.2% after beating earnings estimates and raising its 2026 forecast, providing some cushion for the Dow's losses. However, the extreme volatility in the chip sector is concerning for many investors, even as non-tech sectors show strength.
Oil prices gave up earlier gains, with US crude falling 0.3% to $79.37 a barrel and Brent crude down 0.1% to $84.91 per barrel. US Treasury yields rose, with the 2-year note yield up 3.6 basis points to 4.164% and the 10-year note yield rising 2.84 basis points to 4.573%. The dollar edged higher against major peers, remaining near a one-month low. Precious metals also fell, with spot gold dropping 1.1% to $40 per ounce.
The sell-off in chip stocks, which have seen a nearly 70% increase this year, reflects investor expectations for "perfection" in a sector that has been heavily bet on for artificial intelligence-related growth. Analysts anticipate S&P 500 companies to post 24.8% year-on-year earnings growth for the second quarter, with technology earnings specifically projected to jump 65.5%.
