Backtest copying Thomas MacArthur this year
What copying Thomas MacArthur would have returned
$10,000 invested on 2015-03-05, buying and selling the same stocks 3 days after each filing became public, ended at $34,996 on 2026-11-10. The same money in the S&P 500 (SPY) ended at $38,147.
That headline is diluted by cash: on average only 96% of the money was invested, because the portfolio holds a few small positions. On the 2,938 days it did hold stocks, the copied holdings returned +9.6% a year against +12.3% for the S&P 500 over the same days: 2.7 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.
