GM calling for 4th straight month of improved U.S. market share

With momentum on its side, General Motors is calling for its fourth straight month of increased U.S. market share. GM's market share has been on the rise since July, capped off by the automaker's first year-on-year sales increase since January 2008 last month.

November is far from over, but Mike DiGiovanni, GM's executive director of global market and industry analysis, expects the Detroit automaker to post its fourth consecutive month of increased market share. "We're having a solid month," DiGiovanni told Automotive News.

DiGiovanni failed to predict what GM's market share will be at the end of November, but GM's October market shared checked in at 21.1 percent. GM's market share has been on a steady rise since July's 18.9 percent.

J.D. Power expects November's sales to grow by 0.4 percent, accounting for two fewer selling days compared to last year.
