What copying Alan S. Lowenthal would have returned
$10,000 invested on 2014-01-14, buying and selling the same stocks 3 days after each filing became public, ended at $37,451 on 2026-11-09. The same money in the S&P 500 (SPY) ended at $44,286.
That headline is diluted by cash: on average only 82% of the money was invested, because the portfolio holds a few small positions. On the 3,222 days it did hold stocks, the copied holdings returned +11.3% a year against +12.2% for the S&P 500 over the same days: 0.9 percentage points behind the index.
