Exxon Mobil Corp. has taken back its crown as the most valuable company in the world, despite a stock that has made no gains this year though mid-April. Although the energy reserves of the Irving, Texas, company are considerably smaller than many state-owned energy companies around the world, ExxonMobil is the world's largest oil refiner. Thus, its fortunes are tied to the price of oil and gasoline, which was falling in mid-April. ExxonMobil's stock price may have stagnated so far this year, but it regained the top spot because Apple shares have fallen much further, more than 40 percent since peaking last fall.
