Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.
In 2026 Q2, 249 hedge funds were net buyers of ACMR (122 opened a new position, 127 added to an existing one), while 148 reduced or exited (101 trimmed, 47 sold completely) — a 63% buyer ratio, indicating clear institutional accumulation.

Buying streak — 6 quarters in a row: For 6 consecutive quarters, more hedge funds added ACMR than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.
More buyers than sellers — 63% buying: Last quarter: 249 funds were net buyers (122 opened a brand new position + 127 added to an existing one). Only 148 were sellers (101 trimmed + 47 sold completely). A clear majority buying is a strong confirmation signal.
Elite ownership — 58% AUM from top-100 funds: 55 of 372 holders are among the 100 largest funds by AUM, controlling 58% of total institutional value in ACMR. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
Mixed — 33% long-term, 40% new: Of the 380 current holders: 125 (33%) held >2 years, 102 held 1–2 years, and 153 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
As of today, ACMR has moved -15.7% since the 2026 Q2 13F filing date (August 14, 2026), compared to -0.2% for the XLK sector ETF — an outperformance of -15.5%. Since the quarter end (June 30, 2026), ACMR has gained -46.6% vs -0.5% for XLK. The stock is tracking its sector benchmark closely. The signal remains fresh and the entry point is still near the fund's implied reference.
