Berkshire Hathaway

Berkshire Hathaway is an American investment conglomerate whose public identity is inseparable from Warren Buffett, who began accumulating its stock in 1962 when it was still a textile manufacturer , and Charlie Munger, who joined in 1975 and served as vice chairman until his death in November 2023 at age 99 . Buffett has described Munger as the architect of Berkshire's shift from "cigar-butt" value investing to building a portfolio of high-quality businesses, crediting him with breaking his old habits and establishing the empire's current form . The company continues to be defined by Buffett's annual shareholder letters, which he writes personally and which, as of the 2023 letter, carry what one observer called "Munger's soul" throughout .elsewhere's corpus does not cover Berkshire's current portfolio composition, AUM, or recent performance in detail.
