The investment bank flagged weakening device sales and slower services growth, warning the stock is trading at an expensive multiple despite near-term headwinds.

What Triggered the Downgrade

KeyBanc downgraded Apple (AAPL) to Underweight, issuing a $250 price target on the stock—implying roughly 21% downside from recent levels. The firm's primary concern: iPhone growth is cooling faster than the market expects, and it's not just the phones. Services growth, which has become a crucial profit driver, is also expected to decelerate.

The Real Evidence: Spending Data

KeyBanc cited spending data showing a clear signal: indexed spending declined 2% month-over-month—well below the three-year average of positive 9% growth. That gap matters. It suggests consumers are either holding back on upgrades or spreading purchases over longer periods, both red flags for near-term revenue.

Services Growth Expected to Slow

The Street currently expects Services growth to hit 12%, but KeyBanc sees it moderating to 7%—a meaningful miss to consensus. Services revenue has become Apple's ballast during iPhone cycles, so any slowdown there removes a key support. Combined with softer device sales, the math gets tougher for investors.

The Valuation Problem

Even with Apple's brand strength and ecosystem stickiness, KeyBanc sees the current 35x forward P/E ratio as expensive for a company facing slower growth. The downgrade essentially says: the stock already prices in a lot of good news, leaving little room for disappointment. Paired with actual spending weakness, that's a dangerous combination.

The takeaway for retail investors: this isn't panic—it's recalibration. Growth expectations are coming down, and the valuation discount to support that shift may not be there yet.
