RLAY ranks #2396 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
RLAY is a top-conviction position for Casdin Capital, LLC — at 15.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in RLAY belongs to Sb Investment Advisers, but the position matters far more to Casdin Capital, LLC, who has 15.0% 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.

RLAY 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 2026-06-30 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.
