Over the trailing one-year period, the stock delivered a total return of 68.2%, dramatically outpacing the S&P 500’s performance by 57 percentage points. The stock reached a 52-week high of $45.12 in October 2025, underscoring the rally’s strength.

The company’s $2.12 billion market capitalization reflects its growing importance in semiconductor manufacturing infrastructure.

What ACM Research Actually Does

ACM Research develops and manufactures specialized equipment for semiconductor production, with a focus on single-wafer wet cleaning and electrochemical plating systems. The company leverages proprietary technologies including space alternated phase shift and timely energized bubble oscillation to deliver advanced cleaning solutions.

The company operates through a direct sales force and third-party representatives, serving integrated circuit manufacturers globally. As semiconductor manufacturers pursue next-generation chip architectures with increasingly complex requirements, equipment providers like ACM Research play a critical role in enabling yield optimization and production efficiency.

Investment Perspective

Seldon Capital’s decision to establish this position in Q3 proved well-timed, as the stock subsequently reached new highs. The $7.56 million trading capital deployment came ahead of the October peak, suggesting the fund’s research team identified value before the broader market recognized the full extent of ACM Research’s business momentum.

The combination of strong organic growth, improving profitability, and favorable industry dynamics positions ACM Research as a significant participant in the semiconductor equipment market. Investors evaluating this stock should consider both the impressive financial trajectory and the company’s critical role in supporting semiconductor manufacturing advancement.
