IBD 50 company Sherwin-Williams fell short of first-quarter sales and earnings estimates Thursday as the impact of foreign currency translation hurt the paint and coatings supplier, though it gave an upbeat Q2 forecast. The Cleveland-based Sherwin-Williams (SHW) reported Q1 earnings of $1.42 a share excluding special items. They were up 25% from the prior year but 2 cents below consensus estimates.
