This quarter they opened Micron Technology Inc and trimmed Nvidia Corp. Their largest long position is Nvidia Corp at 11% of the reported non-option book.

Following at the filing date actually beat the quarter-end book by 8.7 points over this window.
Growth of $10,000 cloning Arthur M. Cohen & Associates, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~42 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.
