Apple Stock Slumps Amid App Store Revenue Decline and Soft Guidance

Apple's stock fell by 1.75% on August 21, 2026, due to concerns over its App Store revenue decline and softer guidance for the September quarter.

A Morgan Stanley report showed a 0.6% year-over-year decrease in Apple's App Store net revenue through mid-August, marking the first such drop in four years.

This unexpected dip raised worries about the sustainability of Apple's Services segment growth, which has been a key driver of its profitability.
