Alphabet Has the Second Biggest One-Day Jump in Market Cap Ever

Alphabet Inc. added a historic amount to its market capitalization on Thursday, following blowout quarterly earnings that sent the stock skyrocketing.

The shares rose 10% to $384.80, adding $421 billion to its market valuation, the second-biggest one-day jump in market cap add for any stock ever, according to data compiled by Bloomberg. The record was set about a year ago, when Nvidia Corp. soared by about $440 billion after President Donald Trump announced he was pausing his on tariffs.
