Smart Money Signals — BLDR

Based on 730 hedge funds · latest filing: 2026 Q1 · updated quarterly

📉

Selling streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds reduced or closed their BLDR positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
📊

High ownership — 89% of 3.0Y peak

89% of all-time peak
730 funds currently hold this stock — 89% of the 3.0-year high of 820 funds (reached 2024 Q1). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📉

Outflows — 5% fewer funds vs a year ago

fund count last 6Q
38 fewer hedge funds hold BLDR compared to a year ago (-5% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟡

Slight buying edge — 50% buying

392 buying394 selling
Last quarter: 392 funds bought or added vs 394 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 (-6 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 126 → 114 → 120 → 114. 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.
🔒

61% of holders stayed for 2+ years

■ 61% conviction (2yr+) ■ 21% medium ■ 18% new
447 out of 730 hedge funds have held BLDR 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.
💎

Buying through price weakness — shares -1%, value -69%

Value
-69%
Shares
-1%
Last quarter: funds added -1% more shares while total portfolio value only changed -69%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
➡️

116 → 126 → 114 → 120 → 114 new funds/Q
New funds entering each quarter: 126 → 114 → 120 → 114. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️

Veteran-anchored — 65% veterans vs 22% newcomers

Entry-cohort mix of 757 holders: 491 (65%) are 2+ year veterans, 99 entered 1–2 years ago, and 167 (22%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

41% from top-100 AUM funds
63 of 717 holders are among the 100 largest funds by AUM, controlling 41% of total institutional value in BLDR. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
2.9
out of 10

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.
