What copying Katherine M. Clark would have returned

$10,000 invested on 2014-12-19, buying and selling the same stocks 3 days after each filing became public, ended at $21,655 on 2026-11-09. The same money in the S&P 500 (SPY) ended at $38,921.

That headline is diluted by cash: on average only 74% of the money was invested, because the portfolio holds a few small positions. On the 2,988 days it did hold stocks, the copied holdings returned +6.3% a year against +12.1% for the S&P 500 over the same days: 5.8 percentage points behind the index.
