Despite mounting job losses and a stock market spiraling toward a 12-year low, U.S. consumer sentiment edged up this month according to the most recent results of the RBC CASH (Consumer Attitudes and Spending by Household) Index. The survey, which measured the attitudes of 1,000 Americans earlier this week, found that consumer sentiment remained very low, but stable. As a result, the overall RBC CASH Index stands at 8.2 for March 2009, up slightly from 1.6 in February, the lowest level on record since the inception of the Index in 2002.
