Notable Holders

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.

Terry Smith has trimmed its WAT position for two straight quarters, cutting it by $498.7M while still holding $852.7M.

Game Theory Scenarios

Neutral— Wait & Watch

Dollar-weighted institutional inflow clashes with negative breadth and thin insider data — neutral

Signal Basis

Q2 2026 13F filings show institutional holdings rising ~$14.6B in value, yet net sellers (608) outnumber net buyers (504), suggesting the headline dollar flow masks softer breadth. Insider evidence appears thin: a single director sale of ~$1.44M on 2026-08-06, zero buys, and a 0.0 confidence score.

Confirmation

Confirmation would require next quarter's 13F breadth flipping to net-buyer dominance alongside renewed insider purchasing activity.

Invalidation Risk

A widening gap in seller count, or additional insider disposals accumulating over subsequent windows, could tilt the reading toward distribution.

AI-assisted, sourced directly from institutional holders' SEC EDGAR Form 13F filings, covering historical data only. Should not be the sole basis for any trade.

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 2026-06-30 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.
