Oil swings and AI selloff cap volatile week for stocks

Michael Reinking, Senior Market Strategist at the NYSE, describes a week defined by sharp reversals as the S&P 500 reached a record high on Tuesday before reversing course. Rising oil prices and increasing global yields subsequently weighed on equity markets, capping the early gains. Crude oil prices fluctuated by more than 5% following attacks in the Strait of Hormuz. The energy sector stabilized only after President Trump stated that no strike on Iran would occur before the midterm elections.

A late Thursday selloff in artificial intelligence stocks altered market breadth. The decline pushed the ICE semi index down approximately 4%, while the equal-weight S&P 500 outperformed its cap-weighted counterpart. Investors interpreted Friday’s soft jobs report as evidence of a balanced economic environment, a view Reinking characterizes as goldilocks. The FOMC minutes released during the same period indicated broad support for a September interest rate hike.

Reinking points to inflation data, retail sales figures, and the beginning of the bank earnings season as the primary focus for the coming week. These releases will test whether the recent volatility reflects temporary positioning shifts or deeper structural changes in market sentiment.
