📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added STMP 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 (96% of max)
96% of all-time peak
243 hedge funds hold STMP 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.
〰️
Stable — ownership unchanged year-over-year
fund count last 6Q
The number of hedge funds holding STMP is almost the same as a year ago (-1 funds, 0% change). No significant rush to buy or sell — institutional backing is holding steady.
🟠
More sellers than buyers — 48% buying
132 buying144 selling
Last quarter: 144 funds reduced or exited vs 132 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
📈
More new buyers each quarter (+44 vs last Q)
new funds entering per quarter
Funds opening a new STMP position: 48 → 33 → 31 → 75. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
💰
Value +79% but shares only +9% — price-driven
Last quarter: the total dollar value of institutional holdings rose +79%, but actual share count only changed +9%. 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.
📈
Growing discovery — still being found
53 → 48 → 33 → 31 → 75 new funds/Q
New funds entering each quarter: 48 → 33 → 31 → 75. A growing number of institutions are discovering STMP each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
Exit risk score 2.9/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
