Arm Holdings plc (ARM) stock analysis, September 25, 2025: ARM tests $139 support after RISC-V threat sparks 4.7% weekly slide

Published September 25, 2025 · ARM chart, levels and live analysis

Key Updates

Arm Holdings shares continued their correction, falling 4.01% to $139.64 since the last report, extending the weekly decline to 4.71%. The main catalyst for the pressure is concern over the company’s competitiveness as RISC-V and other tech solutions gain traction. Despite short-term headwinds, the stock still shows a positive six-month trend (+12.36%) and year-to-date gain (+13.20%).

Current Trend

Arm Holdings is showing mixed dynamics, with a clear short-term pullback while the medium-term uptrend remains intact. A 13.20% annual return is still attractive, but recent volatility and a 4.71% drop over five days signal technical challenges. The 12.36% six-month gain underscores the fundamental resilience of the business model despite current market pressures.

Investment Thesis

The investment case for Arm rests on its dominant position in processor architecture for mobile devices and its growing footprint in the server market. The company benefits from the global shift toward energy-efficient computing and the expanding IoT ecosystem. Key growth drivers include technology licensing, royalties from partner chip sales, and potential in artificial intelligence and autonomous vehicles.

Thesis Status

The thesis faces mounting challenges from increasing competition by open architectures such as RISC-V and other tech solutions. The current pullback reflects investor worries about Arm’s ability to maintain tech leadership in a changing competitive landscape. Nonetheless, the continued positive annual performance points to the durability of the underlying fundamentals.

Key Drivers

The primary negative driver is heightened competitive pressure from alternative architectures, especially RISC-V, which poses a growing threat to Arm’s dominance in key segments. A comparative look at Coherent highlights the challenges Arm faces in data-center and transceiver innovations.

Technical Picture

Technical analysis shows a descending correction forming from the $145.47 level reached in the prior report. The current price of $139.64 sits at a technical support zone, but ongoing seller pressure raises the risk of further downside. Weekly volatility has spiked, calling for a cautious short-term positioning approach.

Bull Case

  • Maintaining a positive annual return of 13.20%, demonstrating the business model’s fundamental strength
  • Six-month growth of 12.36% confirms medium-term upside amid technological transitions
  • Dominant mobile ecosystem position provides steady royalty streams from leading chip makers
  • Rising demand for energy-efficient processor solutions as IoT and autonomous systems expand
  • Potential to broaden server-segment presence and AI-focused offerings
