13F filings cover US-listed holdings and arrive up to 45 days after quarter end, so positions may have changed since.
Stakes of 5% or more
No 13D or 13G filing on WDC in the last two years from the filings we read (13G only for companies we track; the sweep began Sep 2026).
A 13D means the holder crossed 5% with intent beyond passive ownership and had to state a purpose; a 13G is the passive version. Every new 13D on tracked companies.
