Artificial intelligence stocks have dominated market gains for over a year, powering many of 2025's top performers in the S&P 500 Index. Investors poured capital into chipmakers and software firms, betting on an infrastructure boom that seemed unstoppable. That momentum is now showing cracks as volatility returns to the sector.

Recent pullbacks for previously untouchable names signal a shift in sentiment. Traders who rode the wave are now bracing for swings as the market digests sky-high valuations and questions the timing of returns on massive capital spending. The trade isn't dead, but it's maturing.

Investors are seeking a broader approach beyond the usual giants, looking for the next wave of beneficiaries. The shift reflects a natural market cycle: early leaders face profit-taking while new candidates emerge. The key question remains whether this is a healthy rotation or the start of a deeper correction for the AI trade.
