10 May 1965: Warren Buffett takes control of Berkshire Hathaway

On May 10, 1965 Warren Buffett's partnership took control of Berkshire Hathaway, a struggling New England textile maker he had bought partly out of irritation with management. Buffett later called it one of his worst investments, a mistake he guessed cost hundreds of billions. Yet he used the dying mill as a vehicle to buy insurance companies and other businesses, building one of the most valuable companies in America.

The lesson: A poor business can still become a great vehicle if the capital is redeployed wisely.

What it meant for investors

$1,000 in Berkshire Hathaway at the start of 2000 → $12,500 today, vs $4,626 in the S&P 500.

We start the clock at the start of 2000, the first year in our price data after the event. That is 12.5 times the money, and $7,874 more than a plain index fund made over the same years.

What Berkshire Hathaway teaches: Being willing to look foolish during a mania, and keeping cash for the moment others are forced to sell, is a durable source of returns.
