BOSTON (Reuters) - Blackstone Group, the world’s largest hedge fund investor, is committing $150 million in start-up capital to a hedge fund run by a former senior executive at Lone Star Funds, two sources familiar with the matter said. Anand Balakrishna Madduri is launching ApaH Capital Management with roughly $200 million in assets, including the capital from Blackstone, one of the people said. Hong Kong-based ApaH will concentrate on public and private market investments across Asia, including in Australia, China, India and Japan.
