AI-Focused Stocks Outperform Broader Market as 10-Year Treasury Yield Surpasses 5%

The yield on the 10-year U.S. Treasury note surpassed 5% in intraday trading last week, a level not seen in nearly 20 years, creating significant headwinds for equities. The pressure was evident in major indices, with the Dow Jones Industrial Average recording its third consecutive weekly loss in its worst stretch since March, according to data from Investing.com.

Market Reacts to Rising Rates

A move of this magnitude in the benchmark Treasury yield typically weighs on stock valuations. Higher yields on government bonds offer a safer alternative for investor capital, and they increase the discount rate used to calculate the present value of future corporate earnings, making stocks appear less attractive.

The recent spike in yields followed the Federal Reserve's rate hike on September 16, which brought the federal funds rate to a range of 3.75%-4.00%. The market reaction reflects expectations of a higher-for-longer interest rate environment, a challenging backdrop for most equity investors.

AI and Tech Stocks Defy Trend

Despite the broad market pressure, a specific segment of the market has demonstrated notable resilience. According to performance data from Investing.com's AI-driven model portfolios, strategies heavily weighted toward technology and AI infrastructure are significantly outperforming their benchmarks month-to-date.

One such portfolio, the "Beat the S&P 500" strategy, has gained 4.74% month-to-date, far outpacing the S&P 500 index's modest 0.25% gain over the same period. The source attributes this outperformance to strong gains in a handful of key technology names:

• Intel (INTC): +22.06%
• Advanced Micro Devices (AMD): +21.80%
• Hewlett Packard Enterprise (HPE): +19.74%

Similarly, a "Tech Titans" model portfolio was up 6.84% month-to-date, outperforming the S&P 500 by over six percentage points. The data, current as of September 21, 2026, suggests that strong, company-specific catalysts in the AI sector are currently outweighing macroeconomic concerns for these select stocks.

Investor Focus on AI Infrastructure

The divergence highlights a powerful theme driving markets: sustained demand for AI hardware and data center infrastructure. The performance of semiconductor and enterprise hardware companies suggests investors believe the growth prospects in AI are strong enough to offset the drag from higher interest rates.

This trend is further supported by the positive performance of semiconductor-focused ETFs like the VanEck Semiconductor ETF (SMH) and the iShares Semiconductor ETF (SOXX), which both gained over 2% during the same week the Dow fell. The data indicates a clear rotation toward companies positioned to build out the foundational infrastructure for artificial intelligence.
