What Cooke & Bieler LP bought and sold in Q3 2026, against Q2 2026.

New positions

Q2 2026's filing was too long to tell new positions apart.

Share counts compared with the Q2 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: +14.1% /yr; S&P 500 +11.7%
3 years: +15.9% /yr; S&P 500 +22.3%
5 years: +4.9% /yr; S&P 500 +10.6%

A portfolio of the filer's 20 largest 13F positions, weighted by value, bought the trading day after each 13F was filed and held until the next one was: what copying this filer could have earned. 13Fs show long US-listed positions only, so this is an estimate of the stock picks, not the fund's reported returns.
