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
Christopher Bloomstran's $880M Semper Augustus portfolio saw its most decisive move in the aggressive build of BLDR (Builders FirstSource), which more than doubled (+142.6%) to 5.6% of the book — a notable bet on housing-adjacent value at a time when many peers are avoiding the sector. On the other side, Bloomstran continued his retreat from consumer discretionary stress: SBUX was slashed 81.8% to a rounding error (0.5%), CMI cut 67.2% to 1.0%, and FIVE trimmed 45.2% to 2.1%, suggesting fading conviction in both the turnaround narrative and cyclical industrials near-term. Six new positions were initiated — PAYX (2.4%), SPGI (2.1%), and CTSH (1.7%) headline the list — pointing toward a rotation into high-quality compounders with durable cash flows, consistent with his Berkshire-influenced style. Combined BRK/B and BRK/A remain the portfolio's anchor at ~25.6% of assets. Watch whether DG and DLTR (combined ~15.9%) are trimmed next quarter, as dollar-store fundamentals remain under pressure and Bloomstran's patience with underperformers has clearly shortened.
