AI Giants Drive Stock Records Despite Rising Treasury Yields

Stock markets hit record highs this week despite surging Treasury yields, a trend attributed to the dominance of artificial intelligence giants. The Nasdaq Composite rose about 1% to close at a new record, while the S&P 500 gained 0.66%, nearing its own high from August 13. This rally occurred as the 10-year Treasury yield climbed above 5.34%, and the 30-year yield approached 5.7%. The unusual disconnect between stock and bond markets was driven by strong performances from Meta, Microsoft, and Nvidia, which helped offset broader market pressures.

CNBC's Jim Cramer noted that the gains were fueled by these three tech giants, each benefiting from distinct catalysts. Nvidia's latest chips are generating strong returns for customers, while Microsoft's Copilot AI assistant and Meta's Muse personal agent app are boosting investor enthusiasm. Their substantial market weight, Nvidia alone accounts for about 8.5% of the S&P 500, helped propel the indexes higher, despite rising rates weighing on other sectors.

Cramer cautioned that the bond market may offer a better indication of future direction. He pointed to weakness in traditional safety stocks and utilities as evidence that higher yields continue to pressure large parts of the market. The sell-off in Treasurys, driven by factors like government borrowing needs and strong demand for data center projects, has sent yields higher. Even a weaker-than-expected jobs report last week failed to provide sustained relief for Treasury yields.

Despite the record highs, Cramer remains cautious, emphasizing that the bond market's strength suggests further volatility ahead. He concluded that until pressure from rising rates eases, the bond market may better signal Wall Street's next moves.
