What happened

Arm Holdings (ARM) stock fell 46% from its June 2026 peak to $243.82 by Tuesday as Fed rate-hike odds climbed to 87%, threatening to compress its high earnings multiple. The chip designer posted record full-year revenue of $4.92 billion for fiscal 2026, up 23% from a year earlier, yet has lost nearly half its peak value since June. Shares plunged 9.71% on September 14 alone after AI safety concerns and a hot August producer-price inflation print of 5.4% pushed rate-hike expectations sharply higher. The Federal Reserve decides on September 16, with CME futures pricing an 87% chance of a 25 basis-point hike that would squeeze ARM's 79x forward earnings multiple — and over 100x by several other estimates.

Why it matters

Arm Holdings is not just another chip company: its designs underpin virtually every smartphone made today and are increasingly powering AI-server processors, making it one of the most widely held growth stocks in the sector. Rising interest rates make future profits worth less in today's money, and ARM's share price has long reflected years of near-perfect growth — the kind of high multiple that can reprice sharply when borrowing costs rise. A sustained derating would most affect retail investors who bought in on the strength of ARM's record fiscal-2026 results, which despite beating expectations have not been enough to anchor the stock.
