Based on 1224 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 8 quarters in a row

last 6Q

For 8 consecutive quarters, more hedge funds added CIEN 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

1,224 hedge funds hold CIEN 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 — +117% more funds vs a year ago

fund count last 6Q

+659 new funds entered over the past year (+117% 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.

🟡

Slight buying edge — 58% buying

734 buying521 selling

Last quarter: 734 funds bought or added vs 521 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 (-62 vs last Q)

new funds entering per quarter

Funds opening this position for the first time: 180 → 254 → 325 → 263. 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.

📌

Mixed — 38% long-term, 42% new

■ 38% conviction (2yr+) ■ 20% medium ■ 42% new

Of the 1,224 current holders: 466 (38%) held >2 years, 246 held 1–2 years, and 512 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.

💎

Buying through price weakness — shares +91%, value +39%

Value

+39%

+90%

Last quarter: funds added +91% more shares while total portfolio value only changed +39%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.

📈

Growing discovery — still being found

108 → 180 → 254 → 325 → 263 new funds/Q

New funds entering each quarter: 180 → 254 → 325 → 263. A growing number of institutions are discovering CIEN each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

🏛️

Veteran-anchored — 49% veterans vs 44% newcomers

■ 49% veterans ■ 7% 1-2yr ■ 44% new

Entry-cohort mix of 1,276 holders: 619 (49%) are 2+ year veterans, 93 entered 1–2 years ago, and 564 (44%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

🏆

Elite ownership — 68% AUM from top-100 funds

68% from top-100 AUM funds

71 of 1211 holders are among the 100 largest funds by AUM, controlling 68% of total institutional value in CIEN. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.

5.3

out of 10

Moderate Exit Risk

Exit risk score 5.3/10 — 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.
