After sliding for much of the fall, consumer confidence climbed in the past month and is now more than twice as strong as it was a year ago, according to the most recent results of the RBC CASH (Consumer Attitudes and Spending by Household) Index. Driven by a strong upswing in expectations for the near-term economic future, the RBC Index for December 2009 stands at 39.0, up 8 points from November's 30.2 reading. A year ago, in December 2008, the RBC Index stood at 15.3.
