Spent the weekend going through SEC 13F filings, Berkshire annual letters, and the partnership letters from the 1960s to map out every major position Buffett ever took.
Interactive page with the full timeline, partnership returns vs the Dow, current portfolio breakdown, and a mistakes section (he talks about his losses more than his wins).
Some numbers might be off since a lot of the early data is from biographies, not filings. Happy to correct anything.
I visualized every major investment Warren Buffett made from 1942 to 2025
