Key Points

  • In 1988, Buffett secured permission from the SEC to not disclose Berkshire's trades, lest others follow him.
  • Decades later, he pointed to one stock as an example of "the secret sauce" behind Berkshire's huge gains.
  • Today, its $816 million in yearly dividends provide Buffett more than a 50% annual yield on his investment.
