Chip stocks kept sliding and big bank earnings sent mixed signals, leaving Wall Street searching for direction on a messy Tuesday.
The Nasdaq ends lower as chipmakers fall for a fifth straight session, closing down 0.15% at 27,204.38 on October 13, 2026, while investors in New York digested weak semiconductor trading and a mixed round of third-quarter bank earnings from Citigroup, Goldman Sachs and JPMorgan Chase.

Nasdaq Ends Lower As Chipmakers Fall Across Memory And Storage Names
The damage was concentrated in memory and data-storage stocks. Micron Technology dropped 4.6%, and Western Digital and Seagate both fell between 1% and 2%. Applied Materials, SanDisk and South Korean chipmaker SK Hynix also slid during the session, adding to a rough stretch for the sector. The Philadelphia Stock Exchange Semiconductor Index fell 0.23%, marking its fifth losing session in a row.
Even before the opening bell, the mood was shaky. Nvidia, Broadcom and Qualcomm each dipped about 1% in premarket trading, while Micron slipped roughly 3%. That early weakness carried through the day, dragging the tech-heavy Nasdaq into negative territory even as other parts of the market held steadier. The Dow Jones Industrial Average fell harder, down 0.35% to close at 51,670.10, while the S&P 500 barely moved, slipping just 0.02% to 7,805.83 according to one market tracking service.

China Chip Competition And South Korea Selloff Add Pressure
Behind the numbers sits a real worry: competition from China. Reports said ChangXin Memory Technologies, known as CXMT, plans to release a more powerful memory chip by the end of 2026. That news rattled investors already nervous about pricing and market share in the memory business, where margins can swing fast when a new rival shows up with better technology.
South Korea's Kospi index added fuel to the fire, tumbling 5.5% to its lowest level since July 31. Since South Korea is one of the world's biggest centers for memory-chip manufacturing, a steep drop there tends to spill into how traders view chip stocks everywhere else, including on Wall Street. Broadcom CEO Hock Tan added his own note of caution a day earlier, on October 12, comparing some of the money flowing into semiconductor investments to “casino gambling.” His comment landed right as investors were already second-guessing how much further the AI-fueled chip rally could run.
Banks Deliver Profits But Investors Still Punish The Stocks
Earnings season kicked into gear with a strange twist: several banks beat profit expectations, yet their shares still fell. Citigroup topped analysts' profit forecasts but saw its stock drop anyway, down 3.4% in one market report and as much as 5.6% in another. Goldman Sachs fared better, posting a 29% jump in third-quarter profit from a year earlier thanks to strong trading and dealmaking, though its stock moved in different directions across reports, rising about 0.5% early on before being described as down 0.2% by the close.
Wells Fargo beat earnings-per-share estimates but missed on net interest income, and its shares fell about 1.5%. JPMorgan Chase had the roughest outing of the big lenders, posting a rare profit miss with net income and revenue below forecasts, even though it raised its 2026 guidance for net interest income. The KBW Nasdaq Bank Index, which tracks major banking stocks, fell more than 1% for the day, a sign that investors cared more about revenue quality and future outlook than just whether a company beat a headline number.
Oil Prices And Earnings Season Keep Markets On Edge
This chip-and-bank tension didn't appear out of nowhere. The session followed a rough Monday, October 12, when the Nasdaq fell 0.44% after oil prices jumped nearly $2 a barrel following attacks on a Saudi airport. Higher oil prices tend to stir up inflation worries, which can complicate the outlook for interest rates and squeeze corporate profit margins, adding yet another layer of uncertainty just as banks were about to report.
Put together, investors were juggling three storylines at once: a chip sector facing fresh competitive threats from China, a banking sector delivering uneven results despite decent headline profits, and an energy market stirring up inflation nerves. None of these threats were new on their own, but hitting all at once made for a jumpy, indecisive trading day across major indexes.
What Comes Next For Chip Stocks And Bank Earnings
More earnings reports are coming, and traders will be watching closely for clues on whether banks can turn around net interest income and keep dealmaking revenue strong. On the chip side, all eyes are on CXMT's promised chip release by the end of 2026, along with any fresh signs of stress or recovery in South Korea's market, since that tends to ripple straight into memory-chip sentiment worldwide.
Analysts still sound mostly upbeat about the longer-term story tied to AI spending and chip demand, even after a rough stretch like this one. But Tuesday's session was a reminder that optimism about artificial intelligence doesn't make chip stocks immune to short-term shocks, whether that shock comes from a rival in China, a falling foreign market, or a CEO publicly questioning whether the hype has gone too far.
