Arm Holdings plc American Depositary Shares, ARM

That’s not a typo.

The chip designer now carries a market cap of roughly $453 billion, a P/E ratio of 491, and a beta of 3.77 — meaning it moves fast in both directions.

Over the past 12 months, ARM has climbed 190%, with a 52-week low of just $100.02 sitting far in the rearview mirror.

Analysts Keep Lifting Targets

Wall Street has been busy with the price target calculator. Mizuho led the recent wave, raising its target from $425 to $500 on June 8th, citing ARM’s expanding AGI CPU platform work with Oracle and ByteDance, plus progress in agentic AI through RTX Spark.

Wells Fargo moved its target from $255 to $410, while RBC went from $175 to $260. Rosenblatt bumped theirs from $175 to $270.

Despite the upgrades, the consensus average price target sits at $239 — well below where the stock is currently trading. Of 27 analysts covering ARM, 20 rate it a Buy, six say Hold, and one says Sell.

Insider Charlotte Claire Eaton followed on May 21st, selling 4,000 shares at $282.77 — a 33.88% reduction in her position.

In total, insiders offloaded 301,338 shares worth $66 million over the past three months. Both sales were executed under pre-arranged Rule 10b5-1 trading plans.
