Hold

Ten-year thesis

The installed base is the moat. Switching costs are photos, messages, Watch, AirPods, and the App Store credential. Services (now a large, high-margin stream) make the hardware replacement cycle less existential than it looks. A ten-year hold is a bet that Apple remains the high-trust consumer computing brand in the West and that it can tax AI as a feature of the phone rather than lose the interface to an open assistant. China and antitrust are the two real cracks.

The moat

Brand, switching costs of the ecosystem, and scale in silicon and retail. Network effects inside iMessage and the App Store. Not a pure network; a gilded cage that customers enjoy.

Switching costs92

Pain, risk, or retraining required to leave.

Network effects80

The product gets better as more people use it.

Intangibles & IP88

Patents, data, licenses, process knowledge, regulation.

Scale advantage90

Fixed costs spread over a volume rivals cannot match.

Cost advantage74

Structural ability to be the low-cost producer.

Brand98

Pricing power from trust, habit, or identity.

Tech overlay

Buffett already crossed this one off the 'too hard' pile. The remaining work for a tech owner is the services mix, App Store regulation, and whether the next interface (glasses, ambient AI) still runs through Apple identity.

What can break it

China demand and political risk
App Store fee compression from regulators
A post-phone interface Apple does not control

Owner earnings yield 3.2%. Yield is judged against quality, not against a single hurdle — a fortress can be fairly priced at a lower yield than a fragile name.
