U.S. stock indexes traded firmly higher early Monday as a rise in the price of crude oil boosted energy-related shares. The Dow Jones Industrial Average rose 185 points, or 0.8%, at 24,452, the S&P 500 index climbed by 0.5% at 2,676, with the energy sector up 1.9%. The Nasdaq Composite Index advanced by 0.9% at 7,272. Monday's moves come after a rally in shares of Apple Inc. overshadowed a lackluster April jobs report, which showed that fewer number of jobs were created in the month than had been anticipated by economists surveyed by MarketWatch. Meanwhile, crude-oil prices climbed above $70 a barrel early in the session, their highest level since 2014. With crude futures rising, investors were likely to keep a close eye on comments linked to the Iran nuclear deal. Separately, shares of Athenahealth Inc. jumped after CNBC reported that Elliott Management is preparing an all-cash deal between $155 and $160 a share for the health-care company.
