When identifying manufacturers with durable competitive advantage, look for inventory and net earnings that rise correspondingly. This indicates that the company is finding profitable ways to increase sales which called for an increase in inventory.

Manufacturers with inventories that spike up and down are indicative of competitive industries subject to boom and bust.
