There's a chill in the air and a slight up-tick in confidence. Holiday discounts are coming a bit earlier, too. For retailers, this has been a great combination, leading to the second consecutive month in which retail sales increased.

This follows more than a year of drops. Consumers aren't going crazy, but they are loosening their wallets a little bit. Consumer spending accounts for 70% of the U.S. economy, and the coming holiday season is where the action is -- for the retail sector and, consequently, for everyone else.
