After wiping out nearly 40% of its market cap in 2015, Cummins (NYSE:CMI) stock is showing visible signs of a turnaround this year. The stock was up 15% year-to-date, as of this writing, recovering at a faster pace than rival Caterpillar (NYSE:CAT) which is up only 6% so far this year after losing about 30% value in 2015.
