With 26.4% revenue growth, ARM exemplifies Lynch's favorite fast growers — but at 130x earnings, he'd say the ten-bagger already happened.
ARM is a magnificent fast grower with 26.4% revenue growth and 94% gross margins, but at 130x earnings, Lynch would say the easy money has already been made.
What kind of company is this, and what should I expect?
This framework classifies ARM as a textbook fast grower — the category Lynch spent his career hunting. The 26.4% revenue growth places it firmly in "10-to-40-bagger" territory, with both business segments contributing meaningful growth.
Am I paying a fair price for the growth I'm getting?
Applying Lynch's PEG framework reveals ARM trading at nearly 5x fair value — far above his 2.0 danger threshold. Lynch believed the P/E should roughly equal the growth rate; ARM's 130x P/E for 26% growth violates this principle severely.
Can I explain this to an eleven-year-old?
The growth story passes Lynch's simplicity test beautifully: "They design the blueprints for chips that go in nearly every smartphone." The royalty model provides recurring revenue as device shipments grow, creating the predictable growth Lynch loved.
Are we in the early, middle, or late innings?
This framework sees ARM in late middle innings — growth remains strong but the market has fully discovered the story. The 130x P/E and diminishing price reactions to beats suggest most of the easy gains Lynch sought are behind us.
Applying this framework to ARM reveals Lynch's classic dilemma — a wonderful fast-growing company at a terrible price. The 26.4% revenue growth, 94% gross margins, and simple story ("chips in every smartphone") would excite Lynch, but the 130x P/E ratio violates his core principle that growth must come at a reasonable price. The PEG ratio near 5 sits far above his danger zone, while insider selling confirms what the valuation suggests — the easy money has been made. Lynch would admire the business but wait for a better entry point. Is a great company at any price still a great investment?
