About this profile
Large investors show up in SEC filings under several names. A family office usually files a 13F (quarterly holdings, if it manages over $100M in US equities) under its firm name, while the same money appears in Form 4 filings under the person's or holding company's name when it owns 10% or more of a company or sits on its board. Some — like Cascade Investment — hold most of their stock through large ownership stakes and file no 13F at all.
This page joins those filings into one view. 13F values are as of quarter end and are filed up to 45 days later. Form 4 values use the latest share count reported times a recent price. Neither shows cash, bonds, private companies or short positions.
