Smart Money Signals — SLDB

Based on 156 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added SLDB 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
156 hedge funds hold SLDB 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 — +39% more funds vs a year ago

fund count last 6Q
+44 new funds entered over the past year (+39% 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

103 buying66 selling
Last quarter: 103 funds were net buyers (47 opened a brand new position + 56 added to an existing one). Only 66 were sellers (38 trimmed + 28 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+20 vs last Q)

new funds entering per quarter
Funds opening a new SLDB position: 27 → 15 → 27 → 47. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
📌

Mixed — 30% long-term, 32% new

■ 30% conviction (2yr+) ■ 38% medium ■ 32% new
Of the 156 current holders: 47 (30%) held >2 years, 59 held 1–2 years, and 50 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
💰

Value +65% but shares only +19% — price-driven

Value
+65%
Shares
+18%
Last quarter: the total dollar value of institutional holdings rose +65%, but actual share count only changed +19%. 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

24 → 27 → 15 → 27 → 47 new funds/Q
New funds entering each quarter: 27 → 15 → 27 → 47. 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.
📊

Mixed cohorts — 31% veterans, 34% new entrants

■ 31% veterans ■ 36% 1-2yr ■ 34% new
Of 160 current holders: 49 (31%) held 2+ years, 57 held 1–2 years, 54 (34%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.
✅

Strong quality — 31% AUM from major funds

31% from top-100 AUM funds
43 of 156 holders rank in the top 100 by AUM, accounting for 31% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
4.2
out of 10
Moderate Exit Risk
Exit risk score 4.2/10 — 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.
