In the long run, stocks reflect earnings and the outlook for future growth. Corporate profits surged last year as the U.S. and global economy recovered. Wall Street expects earnings growth to slow as that initial rebound wears off and wages rise in emerging markets. But the elite IBD 50 list includes five companies set to deliver triple-digit profit growth this quarter. Chinese search engine giant Baidu (BIDU) is one, but most are commodity plays: Northern Oil & Gas (NOG), Cliffs Natural Resources (CLF), Silver Wheaton (SLW) and Gulfport Energy (GPOR).
