Arm Holdings (ARM) stock surged 13% on Wednesday after Mizuho raised its price target to $360, up from $290, while maintaining an Outperform rating. The stock hit an intraday high of $345.60 and is up over 210% since the start of 2026.

The new $360 target represents roughly 19% upside from Arm’s most recent closing price of $302.71. If reached, it would be a new all-time high for the stock.

Mizuho’s upgrade was driven by two core views. First, the firm believes demand for DRAM will remain strong through 2027. Second, it sees the total addressable market for high bandwidth memory continuing to grow — both tailwinds for Arm’s semiconductor business.

The broader AI narrative is also playing a role. Arm has been highlighting growing opportunities in agentic AI, which investors are treating as a long-term growth driver.

The company’s gross margin stands at 94.08%, and its market cap has climbed to around $322 billion on the back of today’s move.

Risks on the Radar

The rally isn’t without its caveats. Arm itself flagged new risks tied to demand forecasting as it moves into production silicon.

The company warned that working closely with chip foundries could introduce challenges around supply, yield, and inventory management. These are not trivial concerns for a company scaling into hardware production.

Still, Mizuho’s decision to raise the target — rather than flag caution — suggests the firm views the growth story as outweighing those risks for now.

Where the Stock Stands

ARM’s 52-week range sits between $100.02 and $349.11. Today’s intraday high of $345.60 puts it right at the top of that range.

Average daily trading volume is around 9.2 million. On Wednesday, volume was running at 403,900 — well below average — which means this move is being driven more by sentiment shift than heavy institutional repositioning.

The stock’s year-to-date gain now stands at more than 176%, one of the stronger performances in the semiconductor space this year.

Mizuho’s updated price target of $360 remains the most recent analyst call on the stock as of Wednesday afternoon.
