Apple Inc. became the first U.S. company with a market value of more $800 billion as investors bet the next iPhone will spur a resurgence in sales.

The stock rose 1 percent Tuesday to close at $153.99 in New York, giving it a market capitalization of about $803 billion. The shares have gained 33 percent since the start of the year, helped by a buyback program that Chief Executive Officer Tim Cook extended to total $210 billion last week, from $175 billion last year.
