Rising Treasury Yield Weighs on Indexes as Anthropic IPO Optimism Supports Tech
Reuters reports that bond yields extended their rise and stocks eased, while optimism about an Anthropic initial public offering (IPO) supported technology shares.
Yahoo Finance data accessed via yfinance show the 10-year U.S. Treasury yield at 5.255%, up 0.29% over one day as a relative change in the yield level and 5.78% over one week, with six consecutive daily increases. The S&P 500 fell 0.17% to 7,671 and the Nasdaq declined 0.09% to 26,798, giving both indexes two consecutive down days.
The evidence lets readers distinguish support for one sector from the broader market direction: Anthropic IPO optimism lifted technology shares but did not prevent the major indexes from declining as yields rose. That interpretation would change if subsequent data show the S&P 500 and Nasdaq returning to gains while the 10-year yield continues to rise.
