Wall Street's Volatile Week: AI Stocks Cool, Oil Prices Slide
Micron's strong earnings weren't enough to sustain the AI trade, while falling oil prices offered a potential inflation tailwind.
Wall Street closed out a turbulent week that underscored a growing tension in markets: even blowout corporate earnings can't always keep a hot sector airborne. Micron Technology, the memory chipmaker widely seen as a bellwether for artificial intelligence infrastructure demand, delivered a blockbuster earnings report — and still finished the week lower. The disconnect speaks to how richly valued the AI trade has become, where good news is increasingly priced in before results even arrive.
The cooling in AI-related equities reflects a broader recalibration rather than a collapse in conviction.

The interplay between slowing AI enthusiasm and easing energy prices will likely remain a defining market dynamic in the weeks ahead.
