📉
Selling streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds reduced or closed their ZD positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
🏔️
At the ownership peak (100% of max)
100% of all-time peak
255 hedge funds hold ZD 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 — +6% more funds vs a year ago
fund count last 6Q
+14 new funds entered over the past year (+6% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠
More sellers than buyers — 49% buying
140 buying144 selling
Last quarter: 144 funds reduced or exited vs 140 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
⚠️
Fewer new buyers each quarter (-8 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 38 → 48 → 53 → 45. 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.
🔒
65% of holders stayed for 2+ years
■ 65% conviction (2yr+)
■ 16% medium
■ 20% new
165 out of 255 hedge funds have held ZD 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 +2%, value -19%
Last quarter: funds added +2% more shares while total portfolio value only changed -19%. 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
35 → 38 → 48 → 53 → 45 new funds/Q
New funds entering each quarter: 38 → 48 → 53 → 45. A growing number of institutions are discovering ZD each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️
Deep conviction — 70% of holders stayed 2+ years
■ 70% veterans
■ 8% 1-2yr
■ 23% new
Of 260 current holders: 181 (70%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.
🏆
Elite ownership — 47% AUM from top-100 funds
47% from top-100 AUM funds
37 of 255 holders are among the 100 largest funds by AUM, controlling 47% of total institutional value in ZD. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
Exit risk score 3.6/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
