Based on 367 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 8 quarters in a row

last 6Q

For 8 consecutive quarters, more hedge funds added OII 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.

🏔️

At the ownership peak (100% of max)

100% of all-time peak

367 hedge funds hold OII right now — the highest count in 3.0 years. When ownership is this concentrated, any bad news can trigger a chain reaction: one big fund sells, others follow. This is a classic 'crowded trade' — high popularity doesn't equal safety.

🚀

Fast accumulation — +29% more funds vs a year ago

fund count last 6Q

+83 new funds entered over the past year (+29% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.

🟢

More buyers than sellers — 61% buying

221 buying144 selling

Last quarter: 221 funds were net buyers (91 opened a brand new position + 130 added to an existing one). Only 144 were sellers (108 trimmed + 36 sold completely). A clear majority buying is a strong confirmation signal.

📈

More new buyers each quarter (+40 vs last Q)

new funds entering per quarter

Funds opening a new OII position: 47 → 47 → 51 → 91. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

🔒

57% of holders stayed for 2+ years

■ 57% conviction (2yr+) ■ 15% medium ■ 28% new

210 out of 367 hedge funds have held OII 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.

💰

Value +43% but shares only +1% — price-driven

Value

+42%

+1%

Last quarter: the total dollar value of institutional holdings rose +43%, but actual share count only changed +1%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.

🚀

Acceleration phase — new buyers rushing in

45 → 47 → 47 → 51 → 91 new funds/Q

New funds entering each quarter: 47 → 47 → 51 → 91. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.

🏛️

Veteran-anchored — 63% veterans vs 29% newcomers

■ 63% veterans ■ 8% 1-2yr ■ 29% new

Entry-cohort mix of 372 holders: 236 (63%) are 2+ year veterans, 28 entered 1–2 years ago, and 108 (29%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

🏆

Elite ownership — 52% AUM from top-100 funds

52% from top-100 AUM funds

56 of 363 holders are among the 100 largest funds by AUM, controlling 52% of total institutional value in OII. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.

4.0

out of 10

Moderate Exit Risk

Exit risk score 4.0/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

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.
