About Christopher Bloomstran
Christopher Bloomstran runs Semper Augustus Investments Group, a Colorado-based concentrated value manager whose public reputation rests largely on his exhaustive annual letters — documents that routinely run to triple-digit page counts and function as graduate-level seminars on Berkshire Hathaway's intrinsic value. His 13F reflects that orientation directly: Berkshire common shares across both share classes account for roughly 24% of the disclosed U.S. equity book as of the latest filing, alongside a small number of other deep-value positions in names like Dollar General, Deckers, and Alaska Air. The portfolio is genuinely concentrated — top-five positions approach 49% — which is consistent with his stated conviction-weighted approach rather than closet indexing. Readers should note that 13F filings capture only long U.S. equity exposure; Bloomstran has written publicly about using options and maintaining cash reserves, neither of which appears in the filing, so the disclosed book is an incomplete picture of actual risk positioning.
2026Q2 brief
2026Q2 activity: 7 new positions (top: PAYX, SPGI, CTSH); 1 conviction add (top: BLDR); 1 exit (top: FLEXTRONICS ). Top 5 holdings: BRK/B, ALK, BRK/A, DG, DECK (52% of portfolio).
