It will eventually happen because any cyclical boom has a pull-forward of demand. Semiconductor margins are up 17 percentage points in the last nine months, which is unprecedented and unsustainable. History suggests that once demand ebbs, margins cannot be sustained.
Companies enjoying those margins are adding capacity (e.g., Micron building new capacity for 2028/2030). Eventually margins will peak, suggesting earnings will peak. Semiconductors are growing earnings by over 100% this year, which is not sustainable.
