Warren Buffett maintains consistent investment strategy over multiple decades

Warren Buffett has given the same investment advice for more than 30 years, and his core ideas have not changed. The veteran investor first recommended index funds in a 1993 letter to Berkshire Hathaway shareholders. He argued that ordinary investors can do better than most professionals by putting money into funds that track the S&P 500. Buffett believes strongly in America's ability to innovate and grow. He also says that good investing depends more on personality than on intelligence. Investors should be patient and wait for the right opportunity, like a baseball batter who waits for the right pitch. His consistent message over decades suggests that these principles work across many different economic conditions.
