Apple Is Worth $2 Trillion — 1st American Company To Hit Milestone

Apple has hit $2 trillion in market value, the first publicly traded U.S. company to do so.

The iPhone maker first crossed the $1 trillion milestone just two years ago.

This week, Apple and a handful of other tech giants propelled the S&P 500 index to a new record. Apple's stock is up nearly 60% this year.
