Shares closed up 1% at $331.86, translating to a market cap of just over $4 trillion.

- Capital One Financial (COF) American Express (AXP) and shares of other US banks sank after President Donald Trump called on credit-card companies to cap interest rates at 10% for a year, a move that could wipe out billions in profits for one of the banking industry’s biggest businesses. Capital One, the largest US card issuer, tumbled as much as 8.2% in New York, the biggest intraday decline in nine months, after the president surprised the industry with a move he said could go into effect next week. American Express dropped 4.2% and JPMorgan Chase & Co., No. 2 in the card rankings, dropped 1.6%.
