Arm Holdings plc

ARM does not manufacture chips — it designs the architectures that other companies license to build their own processors. That royalty model means ARM collects revenue on every chip shipped using its IP, from smartphones to AI servers. As ARM-based chips expand from mobile into data centers, the royalty base grows.

ARM trades at a premium because the royalty model is high-margin and scalable. The risk is that the market already prices in significant AI server penetration.

ARM earnings can move the stock 10-15% because the market is pricing the pace of AI server penetration. A beat with strong licensing guidance signals that more companies are designing ARM-based chips, which validates the multi-year thesis. A miss suggests the transition is slower than expected.

The stock often gaps hard on earnings and then trends for the rest of the week. The opening range framework helps define entries after the initial gap because ARM's post-earnings direction tends to persist.

ARM trades at a significant premium to other semiconductor stocks because the market is pricing years of AI server royalty growth. That premium means any disappointment can produce a sharp decline because the expectations bar is high.
