Rising Treasury yields sank MRVL 6% despite a bullish UBS AI note, exposing the risk of a 176% year-to-date run. AVGO and NVDA fell just 2% each versus Marvell's 5% drop, confirming rate-driven selloffs punish the most-extended stocks hardest. UBS analyst Timothy Arcuri sees MSFT's ASIC relationship potentially adding between $1 billion and $2 billion in revenue if procurement exceeds 1 million units.
Act now: the analyst who called NVIDIA in 2010 just named his top 10 AI stocks — and Marvell Technology didn't make the cut. Grab the names FREE today. Marvell Technology (NASDAQ:MRVL) stock is down 6% Tuesday morning to $219.28, giving back part of a massive 2026 rally as rising Treasury yields pressure the semiconductor group.
That drop lands despite a bullish new UBS research note on the company's AI franchise. Peers are trading lower too. Broadcom (NASDAQ:AVGO) stock is down 2% to $384.59, while NVIDIA (NASDAQ:NVDA) stock is down 2% to $220.22.
Semiconductor benchmarks slid with them. The iShares Semiconductor ETF (NASDAQ:SOXX) shares are falling 4% to $537.48, and Marvell is the most extended name in the group heading into a scheduled earnings report. Through Monday's close, Marvell stock was up 176% year to date, one of the strongest runs in large-cap tech.
Those gains are now colliding with a jump in long-term rates nine days ahead of the company's fiscal Q3 2026 earnings report. This move is macro-driven. Rising Treasury yields and higher borrowing costs are weighing on high-multiple technology names, and Marvell shares sit squarely in that category after a triple-digit 2026 run.
The mechanism is straightforward. Higher yields raise the discount rate applied to distant future earnings, which compresses valuations most for the stocks whose cash flows sit furthest in the future. Semiconductor leaders that have run hard in 2026 fit that profile, and Marvell is the most extended of the group.
