U.S. home builder sentiment ticks up in March, still sour

``U.S. homebuilder sentiment edged up in March but sentiment remained mostly poor as concerns linger, the National Association of Home Builders said on Monday. The NAHB/Wells Fargo Housing Market index rose to 47 in March from 46 in February, the group said in a statement. February's decline was the largest ever month-to-month, and economists polled by Reuters had predicted the index would rebound to 50 in March''
