Retail investors poured more than $24 million into Berkshire Hathaway's Class B stock on Monday, proving it's not just a Warren Buffett cult stock and providing a vote of confidence in incoming CEO Greg Abel.

Buffett talked about U.S. trade, the stock market and his own future at Berkshire Hathaway's annual shareholder meeting. Here are the highlights.

Buffett, one of the world’s richest people and most accomplished investors, took control of Berkshire Hathaway in 1965 when it was a textiles manufacturer. He turned the company into a conglomerate by finding other businesses and stocks to buy that were selling for less than they were worth.
