The broad S&P 500 index fell 0.9 percent, the Dow Jones industrial average fell 1.2 percent and the tech-heavy Nasdaq composite index fell 0.9 percent.
Among the companies that fell were chip giant Nvidia, down 1.9 percent, and iPhone manufacturer Apple, which fell 1.8 percent.
Among the winners was Google parent company Alphabet, which rose 3.1 percent after the announcement that investment firm Berkshire Hathaway, led by the legendary Warren Buffett, owns shares worth $4.3 billion in the tech giant. This means that the Alphabet holding is now Berkshire Hathaway's tenth largest investment.
Danish Novo Nordisk, which on Monday announced a price cut for its diet pills in the US, rose 0.5 percent. The pharmaceutical company is listed in both Copenhagen and New York.
