Any reason to hang on? NTT Docomo plans to sell its entire stake in an Indian telecom joint venture, adding its name to the roster of cautionary tales for blue-chip firms seeking entry into India's fast-growing but challenging market. Following five years of losses plagued by telecom license cancellations in a corruption probe and repeated delays in rolling out high-speed networks, Japan's biggest mobile carrier said it plans to sell its 26.5% stake in Tata Teleservices by June. Shares of Docomo rose 5.2% to $16.05.
