A mortgage portfolio management company, Altisource separated from Ocwen Financial in August 2009, and since then has seen its stock price rise from $10 to $120. Ocwen remains a major client of Altisource, which added staff in 2012 to keep up with Ocwen’s growing portfolio. Altisource also operates Hubzu.com, an online real estate market that has generated more than 70,000 home sales since 2009. Hubzu expanded into short sales this year, and Altisource wants to grow the service by bringing in banks looking to offload foreclosed homes. --C.G.
