📈
Buying streak — 3 quarters in a row
For 3 consecutive quarters, more hedge funds added STX 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
1,210 hedge funds hold STX 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 — +58% more funds vs a year ago
fund count last 6Q
+443 new funds entered over the past year (+58% 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.
🟡
Slight buying edge — 57% buying
690 buying513 selling
Last quarter: 690 funds bought or added vs 513 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.
⚠️
Fewer new buyers each quarter (-20 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 93 → 233 → 262 → 242. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔒
53% of holders stayed for 2+ years
■ 53% conviction (2yr+)
■ 17% medium
■ 30% new
646 out of 1,210 hedge funds have held STX 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 +18% but shares only +1% — price-driven
Last quarter: the total dollar value of institutional holdings rose +18%, 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
92 → 93 → 233 → 262 → 242 new funds/Q
New funds entering each quarter: 93 → 233 → 262 → 242. 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.
🏛️
Deep conviction — 61% of holders stayed 2+ years
■ 61% veterans
■ 9% 1-2yr
■ 30% new
Of 1,280 current holders: 778 (61%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.
🏆
Elite ownership — 51% AUM from top-100 funds
51% from top-100 AUM funds
46 of 1210 holders are among the 100 largest funds by AUM, controlling 51% of total institutional value in STX. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.

Moderate Exit Risk
Exit risk score 4.6/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
