Sound Shore Management Inc (copied at disclosure) S&P 500

The reported book (valued from quarter-end) returned +315.1%, a 13.8-point gap that is the cost of the ~37-day 13F disclosure lag a real follower can't avoid.

Growth of $10,000 cloning Sound Shore Management Inc's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~37 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.
