TheStreet reported that nearly two-thirds of U.S. issues declined and that the S&P technology sector fell more than 3%, while the energy sector rose 2.52%.

It said technology companies have borrowed heavily to fund that spending, and that rising global bond yields raise questions about whether they can keep it up. The AP put the 10-year Treasury yield at 5.09%, after it topped 5.30% earlier in the month. [1](https://bnnbloomberg.ca/markets/dow-jones/2026/10/16/us-markets-weighed-down-by-extended-sell-off-in-the-tech-sector) The AP also cited inflation. It reported that consumer and wholesale inflation readings came in hotter than economists expected, and that, per CME Group data, traders saw a 74.3% chance of a Federal Reserve rate hike in December, up from 50.2% a month earlier. It said Fed Chair Kevin Warsh gave no new policy signals while in Bangkok. [1](https://bnnbloomberg.ca/markets/dow-jones/2026/10/16/us-markets-weighed-down-by-extended-sell-off-in-the-tech-sector) TheStreet quoted Daniela Hathorn of Capital.com as saying the hotter CPI report pushed Treasury yields higher and renewed concerns about financing the AI boom, leaving the Nasdaq especially exposed. TradingKey listed concerns about Chinese semiconductor competition and debt-funded AI expansion among the pressures on chip shares.

TradingKey reported the Philadelphia Semiconductor Index fell 3.83% to 11,137.29, with all 30 of its components lower. The AP listed declines of about 6% for Advanced Micro Devices, 5.8% for Intel, 5.6% for Micron, 4.5% for Broadcom and 3.7% for Meta Platforms.

TheStreet, citing Reuters, put the company's debt at about $50 billion and said that figure had fueled concerns the data-center boom is credit-driven. TheStreet also quoted Nvidia chief executive Jensen Huang as saying he was optimistic and that customers' cost of capital is decreasing.

The AP reported Chevron up 2.6% and Exxon Mobil up 2.5% as Brent crude rose 3.7% to $109.86 a barrel, which it linked to the U.S.-Iran conflict and supply concerns around the Strait of Hormuz. Analysts at ING told the AP the market is pricing in a significant risk premium. TradingKey said rising oil prices drew attention to the inflation outlook.

Moves at the individual-stock level, such as CoreWeave's, are reported separately from the broader index decline.

The December rate-hike odds cited by the AP and further inflation data are the other items reporters flagged for the weeks ahead.
