Across its top 20 institutional holders, NTRA's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 14/100, avg. turnover score 46/100).
NTRA ranks #606 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
NTRA is a top-conviction position for Sofinnova Investments, Inc. — at 21.8% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in NTRA belongs to Jpmorgan Chase & Co, but the position matters far more to Sofinnova Investments, Inc., who has 21.8% 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.
Artemis Investment Management LLP has added to its NTRA position for two straight quarters, increasing it by $45.0M to reach $83.2M today.
TD Waterhouse Canada Inc. has trimmed its NTRA position for two straight quarters, cutting it by $1.8M while still holding $18.4K.
NTRA is down 0.5% today, but institutions show net buying of $12.1B this quarter — a divergence between today's price move and the underlying institutional flow.
NTRA reported a net loss of $192.3M over the trailing twelve months.

Q2 2026
Top 5 Institutional Movers
NTRA 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.
