[U.S. stock technology giants collectively fell, U.S. bond yields fell across the board, are funds turning to safe-haven assets? 】October 22nd, when U.S. technology giants suffered an obvious sell-off, U.S. Treasury yields fell across the board. Market data showed that the Nasdaq fell 2.21%, the S&P 500 fell 1.38%, and the Dow fell 0.64%. Among the top ten companies in the U.S. stock market, nine except Apple fell, with Meta falling 6.51%, Amazon falling 3.86%, TSMC falling 3.56%, Nvidia falling 3.45%, and Broadcom falling 3.28%. At the same time, U.S. Treasury yields generally fell: the 10-year U.S. Treasury yield fell 11.7 basis points to 5.009%, the 2-year Treasury yield fell 12 basis points to 4.697%, and the 30-year Treasury yield fell 8.6 basis points to 5.326%. The pressure on U.S. stocks coincided with the decline in U.S. bond yields, which may reflect the cooling of market risk appetite and the search for safe havens by some funds. It was previously reported that concerns surrounding the huge investment returns in AI are intensifying, and investors are re-examining the safe-haven value of U.S. debt. However, it is not possible to confirm the flow of funds based on stock and bond prices alone, and the actual scale of U.S. bond purchases and market trends still need to be observed in the future.
