Notable Holders

WAT ranks #364 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

WAT is a top-conviction position for Fundsmith Investment Services LTD. — at 7.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in WAT belongs to BlackRock, Inc., but the position matters far more to Fundsmith Investment Services LTD., who has 7.0% 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.

Fort Washington Investment Advisors Inc /oh/ has trimmed its WAT position for two straight quarters, cutting it by $11.6M while still holding $326.5K.

Smart Money Convergence

WAT does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.

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.
