Smart Money Signals — ATRA

Based on 35 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added this stock 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 trade.
📊

High ownership — 92% of 3.0Y peak

92% of all-time peak
35 funds currently hold this stock — 92% of the 3.0-year high of 38 funds (reached 2024 Q2). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
〰️

Stable — ownership unchanged year-over-year

fund count last 6Q
The number of hedge funds holding this stock is almost the same as a year ago (-1 funds, -3% change). No significant rush to buy or sell — the institutional base is holding steady.
🟢

More buyers than sellers — 63% buying

17 buying10 selling
Last quarter: 17 funds were net buyers (7 opened a brand new position + 10 added to an existing one). Only 10 were sellers (8 trimmed + 2 sold completely). A clear majority buying is a strong confirmation signal.
➡️

Steady new buyers — ~7 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 3 → 3 → 6 → 7. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄

Mostly new holders — 34% entered in last year

6% conviction (2yr+) 60% medium 34% new
Only 2 funds (6%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
💰

Value +37% but shares only +9% — price-driven

Value
+37%
Shares
+8%
Last quarter: the total dollar value of institutional holdings rose +37%, 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

8 → 3 → 3 → 6 → 7 new funds/Q
New funds entering each quarter: 3 → 3 → 6 → 7. A growing number of institutions are discovering this stock each quarter. The idea is still spreading — there is room for more buyers to enter.
📊

Mixed cohorts — 6% veterans, 34% new entrants

6% veterans 60% 1-2yr 34% new
Of 35 current holders: 2 (6%) held 2+ years, 21 held 1–2 years, 12 (34%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.

Strong quality — 31% from major AUM funds

31% from top-100 AUM funds
11 of 35 current holders rank in the top 100 by AUM. A meaningful share of the ownership base comes from the most well-resourced institutions.

out of 10
