This quarter they opened Unifirst Corp and trimmed Norfolk Southern Corp. Their largest long position is Norfolk Southern Corp at 8% of the reported non-option book. Cloning the disclosed picks since 2015 would be -23% (-2.3%/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 42.9 points over this window.
Growth of $10,000 cloning Alpine Associates Management Inc.'s disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~21 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.
