Apple’s $191 billion single-day surge sets stock-market record

Apple Inc.’s surge Thursday was one for the record books.

The world’s most valuable company added $190.9 billion in market value, the most ever by a US-listed company, as softer-than-expected inflation data buoyed equity markets across the board. The jump eclipsed Amazon.com Inc.’s $190.8 billion gain in February, according to data compiled by Bloomberg.

Apple, which after Thursday’s 8.8% jump has a market capitalization of $2.34 trillion, now accounts for four out of the top five biggest daily gains. The stock remains down 17% this year.
