Business: Apple becomes first US company to top $800 billion market cap

Apple's record-setting market value eclipsed $800 billion for the first time Tuesday, and its relentless march on Wall Street could take it to $1 trillion later this year.

Shares of the iPhone maker have soared 33% this year, and nearly 40% since the presidential election in November.

On Tuesday, they inched up to $153.96, giving Apple a closing market cap of $802.8 billion — large enough to make it one of the top-20 countries, by gross domestic product,  based on estimates from the International Monetary Fund's World Economic Outlook.
