General Motors is busy phoning friends and posting on its Facebook wall after it made record net revenue in the second quarter of 2016 and boosted its net profit by 157 percent. A net revenue of $42.4 billion is a high point for the company, even though the automaker's global sales were flat compared to this time last year, with 2.4 million vehicles sold. Is it any wonder GM isn't concerned about its falling market share ? It's a great time to be a GM shareholder — thanks to a net income of $2.9 billion, adjusted earnings per share were up 44 percent over the second quarter of 2015. Too bad governments north and south of the border already sold off their remaining shares in the bailed-out automaker — that could have potentially delayed some new taxes. In a release, GM Chairman and CEO Mary Barra said the results "were generated by strong retail sales in the U.S., record sales in China and a continued emphasis on improving the performance of our operations worldwide."
