J. Stern & Co. LLP holds a focused book of 51 reported positions worth $1.1B as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). This quarter Honeywell Aerospace Inc first appears in 13F filings, a listing rather than a purchase; they opened Honeywell International Inc and trimmed Nvidia Corp. Their largest long position is Nvidia Corp at 12% of the reported non-option book. Cloning the disclosed picks since 2025 would be +13% (+16.4%/yr). That is a simulation of the disclosed long book, not audited returns.
Following at the filing date actually beat the quarter-end book by 17.5 points over this window.
Growth of $10,000 cloning J. Stern & Co. LLP's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~45 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.
Top-heavy: focused book
