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 Q1, 322 hedge funds were net buyers of AMKR (130 opened a new position, 192 added to an existing one), while 215 reduced or exited (153 trimmed, 62 sold completely) — a 60% buyer ratio, indicating clear institutional accumulation. This marks 3 consecutive quarters of net institutional buying — a persistent conviction signal. 45% of total institutional value in AMKR is held by top-100 AUM funds, reflecting elite-tier ownership quality. Net fund flow last quarter: +68 funds (more new holders than closures). Total institutional holders: 522.

Buying streak — 3 quarters in a row: For 3 consecutive quarters, more hedge funds added AMKR 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 — 60% buying: Last quarter: 322 funds were net buyers (130 opened a brand new position + 192 added to an existing one). Only 215 were sellers (153 trimmed + 62 sold completely). A clear majority buying is a strong confirmation signal.
Elite ownership — 45% AUM from top-100 funds: 52 of 519 holders are among the 100 largest funds by AUM, controlling 45% of total institutional value in AMKR. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
48% of holders stayed for 2+ years: 251 out of 522 hedge funds have held AMKR for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.
As of today, AMKR has moved +28.7% since the 2026 Q1 13F filing date (May 15, 2026), compared to +8.6% for the XLK sector ETF — an outperformance of +20.1%. Since the quarter end (March 31, 2026), AMKR has gained +100.9% vs +44.0% for XLK. The stock has meaningfully outrun its sector. The trade has partially played out; entry is at a premium to the fund's implied reference.
