(Telecompaper) Alibaba is expected to begin the roadshow for its initial public offering early in the week of 08 September, and its shares could list as soon as 18 or 19 September, a person familiar with the situation told the Financial Times. The marketing trip, when company executives and Wall Street bankers meet with prospective investors, will kick off in Asia and include stops in Europe and the US, the report said. The Chinese e-commerce company is expected to raise about USD 20 billion when it lists on the New York Stock Exchange. A price range for the shares is typically given just ahead of the start of the roadshow. Alibaba also increased its internal valuation to USD 140 billion, from USD 133 billion earlier this month and USD 119 billion in June, according to regulatory filings.
