Share counts compared with the Q1 2026 13F; a split also changes share counts. The latest filing lists more than 50 positions, so a position that left the top 50 may still be held.

How the holdings did against the S&P 500.

1 year: +6.6% /yr; S&P 500 +20.1%
3 years: +12.3% /yr; S&P 500 +20.4%
5 years: +3.5% /yr; S&P 500 +11.6%
