It seems to be a spill over from yesterday. According to MacNN and Macintouch , Apple is expected to cut the price on several desktop models on Aug 1st. I'm still trying to determine what caused the stock to jump today. 20 Apple improved its inventory turn rate from 13 to 22 in Q3. Several readers have asked what that means.
Inventory turn is a measurement of production efficiency.
Imagine that a company's production line is a pipeline. On the other hand, a company with 26 inventory turns would take just 2 weeks. Clearly the latter of the two is more desirable. Higher inventory turn means lower total in-house inventory and shorter response time to changes in market demand. During the conference call, Apple said it intends to further improve its inventory turn rate.
