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.

Buying streak — 4 quarters in a row: For 4 consecutive quarters, more hedge funds added ONTO 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 — 56% buying: Last quarter: 384 funds bought or added vs 298 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.
Elite ownership — 50% AUM from top-100 funds: 62 of 687 holders are among the 100 largest funds by AUM, controlling 50% of total institutional value in ONTO. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
43% of holders stayed for 2+ years: 299 out of 691 hedge funds have held ONTO 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.
