Across its top 20 institutional holders, WDC's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 6/100, avg. turnover score 37/100).
WDC ranks #165 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
WDC is a top-conviction position for Anther Capital Ltd — at 23.1% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in WDC belongs to BlackRock, Inc., but the position matters far more to Anther Capital Ltd, who has 23.1% 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.

Milestone Asset Management, LLC has trimmed its WDC position for two straight quarters, cutting it by $645.9K while still holding $381.5K.

WDC 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.
