Smart Money Signals — SLDB

Based on 135 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, 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
135 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.
📶

Steady growth — +10% more funds vs a year ago

fund count last 6Q
+12 new funds entered over the past year (+10% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 58% buying

80 buying58 selling
Last quarter: 80 funds bought or added vs 58 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.
📈

More new buyers each quarter (+11 vs last Q)

new funds entering per quarter
Funds opening a new SLDB position: 24 → 27 → 15 → 26. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
📌

Mixed — 25% long-term, 24% new

■ 25% conviction (2yr+) ■ 50% medium ■ 24% new
Of the 135 current holders: 34 (25%) held >2 years, 68 held 1–2 years, and 33 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 +50% but shares only +18% — price-driven

Value
+49%
Shares
+17%
Last quarter: the total dollar value of institutional holdings rose +50%, but actual share count only changed +18%. 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.
📊

Peak discovery — momentum slowing

51 → 24 → 27 → 15 → 26 new funds/Q
New funds entering each quarter: 24 → 27 → 15 → 26. SLDB is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
📊

Mixed cohorts — 27% veterans, 38% new entrants

■ 27% veterans ■ 35% 1-2yr ■ 38% new
Of 141 current holders: 38 (27%) held 2+ years, 49 held 1–2 years, 54 (38%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.
✅

Strong quality — 24% AUM from major funds

24% from top-100 AUM funds
41 of 135 holders rank in the top 100 by AUM, accounting for 24% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
3.8
out of 10
Low Exit Risk
Exit risk score 3.8/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

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.
