Arthur Wolcott (Founder and Chairman since 1949) purchased $171,000 of stock across 3 purchases in June 2021 at an average price of $49.61, increasing his stake of Class B shares by 18%, he also owns a similar number of Class A shares (which have 1/20th of a vote). Despite his remarkably long tenure we only have a record of him making 3 previous purchases during 2019-20, most recently at $39.10 in February 2020. This recent cluster of buys is fractionally larger than those prior purchases. This is an unusual large buy from a very long-serving director. We are ranking the stock +1.
