Shares of Arm Holdings (NASDAQ: ARM) tumbled Monday, closing down 8.06% at $215.88, their biggest single-day drop since October, as the chip designer’s recent AI-fueled rise encountered a wall of profit-taking and new investor concerns.

The fall broke a seven-day winning trend and left Arm the worst performing Nasdaq-100 element on the day, Dow Jones Market Data showed. Volume was strong with nearly $2.5 billion in shares changing hands.
From Hero to Headache, at Least for a Day
The reversal comes after a dizzying run for Arm stock, which soared more than 50% from its April 7 low in less than three weeks. Shares rose over 15% on Friday alone after Intel posted a robust first quarter earnings beat with better-than-expected guidance. Intel CEO Lip-Bu Tan cited the greater demand for CPUs, fueled by the move to agentic AI which is a tailwind for Arm, the power-efficient chip architecture dominating in mobile and increasingly in data center workloads.
Monday’s sell-off seems to be driven by two things, including straightforward profit-taking after Friday’s outsized gain, and a broader cooling of AI sentiment across the market. Other stocks including AMD (-3.79%), Marvell (-3.71%) and Credo Technology (-7.45%) also declined. But one worry above all others sharpened Arm’s drop: rumors that Qualcomm and OpenAI could be teaming up on a custom chip — and that Arm’s technology might not be at its core.
Arm Holdings (ARM) in a Key Transition Phase
Arm is at an unexpected point of inflection. In the past the company has licensed its chip architecture to OEMs rather than creating silicon itself. That changed on March 25 when Arm said it would create its own microprocessor, a strategic pivot that sent shares soaring before broader market turmoil around geopolitical concerns drove them back down.
The corporation has a lofty objective of $25 billion in yearly revenue by 2031, which would be a sharp increase from its current size. Arm releases profits next Wednesday and will provide investors with an update on progress.
ARM Stock Valuation Concerns Mount
Even after Monday’s dip, Arm trades at a price-to-earnings ratio of about 130 based on adjusted earnings—a value that allows little space for disappointment. The analyst price estimates range from $125 from Goldman Sachs to $230 from Mizuho, with a median of $175 among 21 analysts, below the current price, showing some on Wall Street see the stock as stretched.
But all seven analysts that have released ratings recently are still positive, with firms including JP Morgan, UBS, TD Cowen and RBC Capital all retaining buy-equivalent ratings.
Arm Holdings Stock Outlook: Insider, Institutional Signals to Watch
Over the last six months, insider activity has been one-way behind the scenes: 13 open-market deals, all sells. CEO Rene Haas sold about 41,000 shares for an estimated $6.6 million and CFO Jason Child sold approximately 42,500 shares for almost $7 million.
The institutional picture is mixed. Notably, Nvidia Corp and Altimeter Capital were the biggest losers, having sold all of their shares in Q4 2025. Companies including as Northwestern Mutual and Two Sigma added to their investments substantially.
Arm’s direction shouldn’t be determined by Monday’s misstep – the fundamental justification for CPU demand in an agentic AI world remains intact. But with a stratospheric valuation, insider selling and next week’s earnings on the horizon, investors seem to be questioning themselves if the stock has just raced too far, too fast.
