Apple Stock Soars on Foldable Phone Debut

Apple's stock price climbed 5.6% this week after new CEO John Ternus unveiled the company's first foldable phone, the iPhone Duo, at Apple Park on September 9.

The Duo features a 7.6-inch display, the largest ever on an iPhone, and supports the Apple Pencil. It starts at $1,999 for the base model and tops out near $3,199 for the top storage tier.

Analysts estimate that the Duo could account for 10% of Apple's total iPhone revenue next year, according to Gene Munster of Deepwater Asset Management.
