The iShares Semiconductor ETF (SOXX) posted an 11% gain last month, extending a prolonged winning streak for semiconductor stocks across the board.
The rally was largely driven by strong investor reaction to Meta Platforms’ new Muse AI personal agent, which debuted to broadly positive reviews mid-month.
Muse is seen as a potential turning point for artificial intelligence adoption, with personal AI agents now positioned as the next major technology wave after chatbots.
If products like Muse and its peer Instinct gain widespread adoption, analysts expect a significant new wave of demand for CPUs, memory chips, and other semiconductor components.
Much of the ETF’s monthly gains were concentrated in the middle of the month, coinciding directly with the surge of attention around the Muse launch, according to S&P Global Market Intelligence.
The SOXX’s top five holdings include Nvidia, Micron, AMD, Broadcom, and Intel, and nearly all of those major chip stocks recorded gains over the period.
Three of the five top holdings delivered double-digit returns, with Intel leading the group at 34%, AMD climbing 30%, and Micron advancing 11% over the month.
AMD and Intel, both CPU manufacturers, have the most direct exposure to agentic AI products like Muse, which explains their outsized performance relative to peers.
Broadcom slipped 5% and Nvidia gained just 3%, reflecting their comparatively limited direct exposure to personal agent-style AI products.
The Federal Reserve raised interest rates by 25 basis points during the month, a move that typically pressures growth-oriented sectors like semiconductors, though the sector continued its climb regardless.
Concerns about AI safety raised by Anthropic CEO Dario Amodei and others also failed to interrupt the broader rally in chip stocks throughout the month.
Toward the end of the month, top AI industry leaders gathered at the White House with President Trump to discuss AI safety issues, though the meeting produced no significant regulatory outcomes.
The combination of strong AI product momentum, resilient investor sentiment, and robust earnings expectations across the chip sector continues to underpin confidence in semiconductor equities heading further into the year.
