Across its top 20 institutional holders, ZNTL's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 17/100, avg. turnover score 45/100).
ZNTL ranks #4250 out of 37696 tracked stocks by institutional interest, inside the more closely watched half of our coverage.
ZNTL is a disclosed holding of Two Sigma (Two Sigma Investments), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.
ZNTL is a top-conviction position for 5AM Venture Management, LLC — at 6.7% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in ZNTL belongs to Squadron Capital Management LLC, but the position matters far more to 5AM Venture Management, LLC, who has 6.7% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.
ZNTL is down 4.9% today, but institutions show net buying of $29.3M this quarter — a divergence between today's price move and the underlying institutional flow.
ZNTL reported a net loss of $139.5M over the trailing twelve months.

Top 5 Institutional Movers
ZNTL does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
