Apple's stock price hit a new record high today on a report that sales of this year's iPhone models had started strongly. Shares of the tech giant climbed 3.9%, closing at $262.24 and helping the company surpass Microsoft to become the second largest in the US by market capitalization (chart). Only Nvidia is larger. That helped to lift the S&P 500 by 1.1%. The recent sharp drop in the index on October 10 in response to President Donald Trump's threat to impose an additional 100% tariff on China and the October 16 decline on regional bank worries have been almost completely reversed. The S&P 500 is only 0.3% below its October 8 record high.
