Arm Holdings plc (ARM) stock analysis, February 18, 2026: ARM breaks $120 after Nvidia exits stake, but $130 caps the next move

Published February 18, 2026 · ARM chart, levels and live analysis

Key Updates

Arm Holdings surged 5.14% to $126.89 since the last report, marking a decisive breakout from the post-earnings correction phase and confirming renewed investor confidence. The rally brings YTD gains to 16.08% and extends the one-month advance to 19.96%, signaling strong technical momentum. Two key developments drove this recovery: Nvidia's complete divestiture of its Arm stake eliminates a potential overhang concern, while the $230 million funding round for AI chip startup Positron—with Arm as a participant—validates the company's strategic positioning in the AI inference market. The price action demonstrates that the memory shortage concerns articulated in early February earnings have been largely discounted, with investors now focusing on Arm's expanding data center opportunity and ecosystem strength.

Current Trend

Arm has entered a strong uptrend, advancing 16.08% YTD and 19.96% over the past month, recovering substantially from the 8.65% six-month decline. The stock has broken decisively above the $120 resistance level that capped prices during the post-earnings selloff, establishing $120 as new support. The 5.14% single-session gain represents the strongest daily performance since the February 5 earnings release, suggesting accumulation by institutional investors. Near-term resistance appears at $130, while the $120 level now provides critical support. The technical setup indicates bullish momentum, with the stock trading well above recent lows near $96 and demonstrating strong recovery from the 35% decline referenced in earlier reports.

Investment Thesis

The investment thesis centers on Arm's structural transition from smartphone dependency to data center dominance, with CEO Rene Haas projecting data center revenue will surpass smartphone revenue within a couple of years. The company commands approximately 50% market share in the data center CPU market, competing against Intel and AMD's X86 architecture, with significantly higher royalty rates from v9 architecture designs driving margin expansion. Despite near-term headwinds from memory shortages constraining smartphone chip volumes, analysts project revenue growth exceeding 20% for fiscal 2026, 2027, and 2028. The thesis is reinforced by Arm's strategic positioning in AI inference workloads, validated by its investment in Positron and the broader industry shift toward Arm-based computing platforms, including Nvidia's upcoming N1 and N1X laptop processors. The company's reach to 100% of the connected global population through 22 million software developers creates powerful network effects.

Thesis Status

The investment thesis remains intact and has strengthened materially since the last report. The memory shortage impact, initially feared to significantly constrain royalty revenues, is now quantified at only 2-4% of smartphone royalties even under a severe 20% volume reduction scenario, according to company guidance. The data center transformation thesis accelerated, with fiscal Q3 data center chip royalties growing 100% year-over-year, as reported by the Financial Times. Nvidia's stake sale, while initially appearing negative, actually removes a technical overhang without signaling strategic concerns—Nvidia continues expanding Arm-based product development with its N1 laptop platform. The Positron investment demonstrates Arm's ability to capture value across the AI chip ecosystem beyond traditional licensing, addressing previous concerns about competitive positioning. Morningstar's $80 fair value estimate, based on 35x forward P/E, suggests the current $126.89 price reflects appropriate optimism while remaining below speculative extremes.

Key Drivers

The primary catalyst is Arm's rapid data center revenue growth, with royalties increasing 100% year-over-year and the segment projected to surpass smartphone revenue within two years, according to CEO Rene Haas. Second, the memory shortage impact has been contained, with management estimating only 2-4% royalty impact from a hypothetical 20% smartphone volume reduction, as detailed in earnings analysis. Third, ecosystem expansion continues with Nvidia developing Arm-based N1 and N1X laptop processors featuring up to 20 CPU cores, challenging the Intel-AMD duopoly, per The Verge. Fourth, Arm's strategic investment in Positron's $230 million funding round positions the company in the AI inference market, diversifying revenue streams beyond traditional licensing. Finally, Nvidia's complete divestiture of its 1.1 million share stake removes a technical overhang without signaling strategic concerns.

Technical Analysis

Arm has established a bullish technical structure, trading at $126.89 with strong momentum across multiple timeframes: up 1.29% daily, 1.83% weekly, 19.96% monthly, and 16.08% YTD. The stock has decisively broken above the $120 resistance level that constrained prices during the February 5-17 correction, converting this level into new support. The 5.14% gain since the last report represents the strongest single-session advance in the recent recovery phase, suggesting institutional accumulation. Volume patterns support the rally, with the price action confirming a higher-low structure from the $96 post-earnings bottom. Near-term resistance appears at $130, representing the next psychological level, while the $120 support zone should contain any profit-taking. The six-month decline of 8.65% has been substantially recovered, though the stock remains below previous highs, providing room for further appreciation without entering overextended territory. The one-month 19.96% surge indicates strong relative strength versus broader semiconductor indices.
