Letter3Q26 Partners Fund Commentary
Mason Hawkins
Deeply contrarian and concentrated, leaning into derated but financially strong holdings, expecting corporate activity and self-help — not market sentiment — to close the price-to-value gap.
“This diversified healthcare company is a new holding (owned previously in the 2010s) and is off to a strong start for us.”
