Warren Buffett, the long-serving chairman and CEO of Berkshire Hathaway (BRK.B) (BRK.A), is well known for his disciplined investment philosophy and clear-eyed warnings about investor behavior. Among his most enduring insights is the principle that “for the investor, a too-high purchase price for the stock of an excellent company can undo the effects of a subsequent decade of favorable business developments.” This quote serves as a cautionary reminder that valuation matters — even when the underlying business is exceptional.
Buffett originally made this observation in his 1982 shareholder letter, addressing a fundamental misunderstanding in investing: the belief that buying shares of a high-quality business guarantees strong returns. His message is clear: no matter how resilient or well-managed a company may be, paying an inflated price at the outset can severely diminish, or even negate, the investor’s eventual gains.
