"You know we're living in strange and perverse times when ExxonMobil can post a $10.9 billion quarterly profit and still fall short of expectations. This past quarter marked the second most profitable quarter ever for the most profitable company in the history of the world -- a 17 percent increase in year-on profits. And like its competitors at BP and Royal Dutch Shell, Exxon managed to increase its profits despite no increase in production. (Funny what happens when the price of oil literally doubles.) Nevertheless, Wall Street was disappointed and the company's shares fell sharply in early trading yesterday."
