Apple's iPhone Boom Can't Shield Its Stock From Memory and Services Worries

Apple's iPhone business is still performing well, with demand for its flagship phones holding up. Yet the company's stock has been falling anyway, a reminder that healthy sales do not automatically settle how investors value a company. The pressure is coming from costs and from the part of the business that was supposed to cushion them.

The most immediate concern is memory. The chips that store data in phones, computers and data centers have become harder to source at reasonable prices as suppliers shift capacity toward AI hardware. Apple buys these components in enormous volumes, so even modest price increases can squeeze profit margins, even when units sell well. The company has long relied on scale and pricing power to absorb such shocks, but investors are asking how long that cushion can hold if the squeeze lasts.

The second worry is services. Apple's App Store, subscriptions, payments and other digital offerings have been a high-margin engine that helped steady earnings through swings in hardware sales. If growth in that segment is slowing, the company loses some of the diversification that supported its premium valuation. Investors who had assumed steady, strong growth from services may now be revisiting that assumption.

Taken together, the picture is mixed. The core product is selling, but the stock reflects doubts about margins and future growth. The next earnings report will be closely watched for guidance on component costs and the trajectory of services revenue. If memory prices ease, the pressure could fade quickly. If they keep climbing, analysts may continue to trim their expectations, and the shares could stay under pressure even while the iPhone keeps selling.
