What's an example of smart money?
Warren Buffett is one of the best-known investors, and he's also a good example of smart money.
Although he may not present as a typical Wall Street billionaire, Buffett has been a master investor for roughly 60 years, and he's built Berkshire Hathaway (BRK.A -1.24%) (BRK.B -1.33%) into a conglomerate that's worth almost $1 trillion.
Buffett is also a highly sophisticated, disciplined investor, and his decades of experiences inform his decision-making. Buffett is so successful that Berkshire's returns have essentially doubled the S&P 500 an average return basis, crushing the broad-market index over the long term. He's also known for coining popular investing concepts like an "economic moat."
It's no surprise, then, that so many investors closely follow Buffett's move each quarter. Investing with him or in Berkshire directly has historically paid off.
