Published Mar. 2, 2015. The consumer sentiment index slid in February as rebounding gas prices and cold temperatures shook household confidence. The University of Michigan’s survey tumbled to 95.4 this month after peaking in January at an 11-year high of 98.1. That’s still far above 2014’s February reading of 81.6 and a bump-up from Bloomberg’s survey expectations of 94.0. Analysts say consumer confidence was shaken after a seven-month plummet in gas prices turned upward in the last several weeks.
