WASHINGTON (MarketWatch) -- U.S. consumer sentiment was unchanged in March amid signs that the labor market is approaching a trough but remains frail, according to media reports of a survey released Friday by the University of Michigan and Reuters. The consumer sentiment index remained at 73.6 in March, matching February's level. In mid-March the estimate was 72.5. Economists polled by MarketWatch were looking for a final March result of 73. The index hit a 28-year low of 55.3 in November 2008.
