Backtest copying Katherine M. Clark this year
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.
Value of the whole copy portfolio including cash (teal) and of the same money in SPY (red), sampled across the period. Green dots are copied purchases and red dots copied sales (at most 300 are drawn).
Gain or loss by month
Monthly return of the whole copy portfolio, cash included. Green months gained, red months lost; darker means a bigger move. Grey months had no change.
255 copy orders were not placed (no price history, no cash left or the position limit was reached) and 126 disclosed lines could not be copied at all (no ticker, options, bonds). Hypothetical result computed 2026-11-09 with data through 2026-11-09; see the methodology. Not investment advice.
