Cardboard Box Index

What Does Cardboard Box Index Mean?
An index used by some investors to gauge industrial production by using the output of cardboard boxes to predict the purchases of non-durable consumer goods.

Investopedia explains Cardboard Box Index
This is considered to be a relatively good measure. It is estimated that nearly 75 to 80 percent of all non-durable goods are shipped in corrugated containers. Therefore, the greater the amount of cardboard boxes being made, the greater the amount of cash being invested by companies to produce goods.
