Arm: the attach rate is the number that matters

What drives this is mix rather than volume. The incremental unit carries a materially higher attach of adjacent silicon than the installed base does, so gross margin rises even in a quarter where units are flat. The disclosure supports this directly. Attach revenue was broken out for the first time last quarter and grew at roughly twice the rate of the core line, off a base small enough that the mix effect is still ahead of it rather than behind. The position: long on Arm, entry locked at publication and the exit dated rather than open-ended. The target is stated in the call block above and the horizon with it. Sized to the catalyst rather than to conviction, with the invalidation written into the kill-switch card instead of left implicit. The main risk is timing rather than direction. Cycles in this industry have turned early and then stalled for two quarters more than once, and the position is sized for that rather than against it.

I came in sceptical. The comp table did more work for me than the narrative did. Has anything in the last print changed the entry you would take?

Ines FerreiraJUL 12

This changed my mind. The destocking signature is textbook and nobody is naming it. Interested in what the kill switch looks like in practice.

Dana KatzJUL 11

Respectfully, I think this overstates it. Second source in a constrained market is genuinely underrated. Does the same logic apply to the closest comparable?

Fair challenge. Invalidation is a close below the lock price on volume, and I should have written that into the card rather than leaving it implicit. (1123)
