Apple Inc today became the first $1 trillion publicly listed United States company, a profound achievement for a company that was days away from bankruptcy only 21 years ago.
The tech company's stock jumped 2.8 percent to as high as $207.05, bringing its gain to about 9 percent since Tuesday when it reported June-quarter results above expectations and said it bought back $20 billion of its own shares.

Apple's stock market value is greater than the combined capitalization of Exxon Mobil, Procter & Gamble and AT&T. It now accounts for 4 per cent of the S&P 500.
One of three founders, Jobs was driven out of Apple in the mid-1980s, only to return a decade later and rescue the computer company from near bankruptcy.
He launched the iPhone in 2007, dropping "Computer" from Apple's name and super-charging the cellphone industry, catching Microsoft, Intel, Samsung Electronics and Nokia off guard. That put Apple on a path to overtake Exxon Mobil in 2011 as the largest US company by market value.
