Beyond the “Magnificent Seven”

The rally extended beyond the most iconic names. Broadcom, for instance, jumped 57% in the last quarter, reaching its highest valuation in five years, while Uber climbed 25%.

“We believe the recent surge in large-cap tech and AI stocks has been primarily driven by P/E multiple expansion,” UBS Financial Services noted. “While we maintain a structurally positive outlook on AI, we would prefer to see gains underpinned by upward earnings-per-share revisions rather than pure valuation expansion.”

Given the lofty valuations, ongoing geopolitical uncertainty, and the upcoming Q2 earnings season, UBS highlighted the importance of a balanced and selective approach.

“We recommend investors seek diversified exposure across semiconductors, software, and internet platforms, rather than concentrating risk in a single segment or individual stock,” the report concluded.
