General Motors Co., which raised more than $20 billion an initial public offering yesterday, will be more aggressive marketing its brands now that it is publicly traded again, the automaker’s top marketer said. “There were things we would have tried or done that we did not do” during the pre-IPO quiet period, Joel Ewanick, GM’s vice president of U.S. marketing, said today in an interview in Los Angeles. “Now, you’ll start seeing more and more.”

SAIC Motor Corp. said that a Hong Kong-based subsidiary had acquired a nearly 1 percent stake in General Motors Co. as part of the U.S. automaker's initial public offering, reports said. The company paid the $33 per share IPO price for 15.15 million shares, or about $500 million, the reports said.
