Following at the filing date actually beat the quarter-end book by 3.0 points over this window.

Growth of $10,000 cloning Jackson Square Capital, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects the ~45-day reporting lag, 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.
