The AI Trade and Global Market Volatility
The rally was not uniform across all sectors. While the Nasdaq Composite gained 2.1%, the AI-driven tech trade continues to exhibit significant instability. Investors are weighing whether the massive spending on data centers by Big Tech will yield the expected productivity and profit.
This volatility was most evident in South Korea, where the Kospi index fell 5.1% on Monday, reversing a historic 17.9% surge from the previous Friday. In Japan, the Nikkei 225 dipped 0.9% after the U.S. and Japan coordinated to prop up the yen.

Treasury yields did retreat as oil prices fell, with the 10-year yield dropping to 4.68% from 4.75% on Friday. Nevertheless, this remains significantly higher than the 3.97% level seen before the conflict with Iran began. These elevated yields continue to pressure mortgage rates and increase borrowing costs for households and businesses.
Investors are now looking toward a critical week of economic data, specifically the government jobs report due Friday. Additionally, minutes from the Fed’s most recent rate-setting meeting are expected on Wednesday, which may provide further clarity on the central bank’s policy path.
The immediate tension for Wall Street is whether the current “animal spirits” can withstand a potential return of volatility in the Middle East. As the market remains range-bound in the second half of the year, the primary risk is the conflict’s impact on energy, freight, and fertilizer markets.
