If you've been watching semiconductor stocks lately, you've seen a bit of a roller coaster. Micron Technology Inc. (MU) and Broadcom Inc. (AVGO) have both pulled back roughly 25% from their recent record highs. That sounds scary, but UBS thinks it's actually an opportunity — not a warning sign.
The declines come after a massive rally fueled by AI demand and data center spending. And despite the volatility, UBS argues that the semiconductor sector is fundamentally strong, not speculative. In other words, this isn't 1999 all over again.
UBS Says It's Not a Bubble
"Semis valuations remain far from bubble territory. Despite the strong semiconductor rally this year, forward price-to-earnings multiples for the Philadelphia Semiconductor index at around 26x today are well below the 150x level at the peak of the dotcom cycle," UBS wrote.
The firm emphasizes that earnings growth is supporting current valuations. The Philadelphia Semiconductor Index, often tracked via funds like the iShares Semiconductor ETF (SOXX), has seen profits rise alongside share prices rather than lag behind them.
"With earnings largely keeping pace with share prices, we remain constructive on the semis complex. Consensus estimates currently imply earnings growth of 92% for the index this year and a further 40% in 2027," UBS said.
Micron is closely tied to memory pricing cycles, and high-bandwidth memory demand from AI server buildouts is a big tailwind. Pricing discipline and constrained supply have helped stabilize margins. The recent pullback in the stock reflects broader sector rotation more than any company-specific weakness.
Broadcom, a heavyweight in the SOXX index, continues to benefit from custom AI chip demand and infrastructure software exposure. Its diversified revenue base makes it a key proxy for AI monetization. The stock's retracement follows a sharp run-up, not a deterioration in fundamentals.
The Takeaway
UBS contrasts the current environment with the late-1990s dot-com era, when valuations expanded far ahead of earnings. Current multiples, while elevated relative to historical averages, are grounded in tangible growth expectations tied to AI, cloud, and advanced computing.
The firm's outlook suggests the recent correction may represent consolidation within a longer-term uptrend rather than a signal of excess. Lower entry points for leading names like Micron and Broadcom could draw renewed interest from investors seeking exposure to semiconductor growth themes.
Of course, macro risks and rate expectations can still drive short-term swings. But UBS maintains that the sector's earnings trajectory provides a stronger foundation than in past speculative cycles.
