AURA ranks #3695 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
AURA is a top-conviction position for Medicxi Ventures Management — at 12.2% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in AURA belongs to TCG Crossover Management, LLC, but the position matters far more to Medicxi Ventures Management, who has 12.2% 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.

AURA 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.

Filings (14d)
On August 11, 2026, Aura Biosciences issued a press release announcing its financial results for the quarter ended June 30, 2026. This 8-K includes that release as Exhibit 99.1 under Item 2.02, which is furnished but not considered "filed" for SEC liability purposes. The filing also lists other items (2.05, 5.02, 8.01, 9.01), but the excerpt doesn't include details on those, so this summary only covers the earnings release.
