About Wally Weitz

Wally Weitz, 'the other oracle of Omaha,' founded Weitz Investment Management in 1983 and compounded a value record heavily influenced by his neighbor Warren Buffett, with a bent toward media, cable, and businesses with pricing power.

The firm's 13F carries that heritage: Berkshire Hathaway, Liberty-complex media names, and quality franchises bought below business value, with the patient turnover of a family-run Omaha shop.

Methodology: turnover is min(value bought, value sold) ÷ average reported value across the two quarters — value-based, so market moves inflate it slightly versus a share-based measure. Concentration and largest position are shares of the filing’s total reported value, options excluded. New/exited counts compare against the prior filed quarter. All figures derive solely from the fund’s 13F filings.
