BEIJING (Reuters) - China’s Zhejiang Geely Holding Group said on Wednesday its Volvo Cars would explore capital market options including a potential initial public offering (IPO) and stock market listing. Geely bought Volvo Cars from Ford Motor Co in 2010. Geely’s Hong Kong-listed unit Geely Automobile and Volvo Cars scrapped their full merger plan in February. Geely’s revived consideration of an IPO for Volvo Cars could value the business at around $20 billion, Bloomberg reported on Wednesday citing people familiar with the matter. A Volvo Cars spokeswoman said the firm would not comment on speculation.
