Some Sector Leaders had notable moves Friday despite a quiet market. Trinity Industries (TRN) rallied 1.99, or nearly 3%, to 76.28 in brisk trade. It hit a new high and closed above a 76.05 buy point from a flat base. It was the first time it finished above the 76.05 trigger since breaking out Wednesday in big turnover. The prior evening, the railcar maker beat views with its first-quarter results.
