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.
Many quality funds hold this stock, but top-tier positions remain relatively small.

Buying streak — 2 quarters in a row: For 2 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.
Slight buying edge — 57% buying: Last quarter: 169 funds bought or added vs 128 that reduced or exited. It's nearly a 50/50 split — some institutions are convinced, others are taking profits. This mixed picture is normal near price highs.
Strong quality — 38% AUM from major funds: 35 of 268 holders rank in the top 100 by AUM, accounting for 38% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
Mixed — 37% long-term, 35% new: Of the 268 current holders: 100 (37%) held >2 years, 73 held 1–2 years, and 95 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.
