The IPO market has served up plenty of compelling growth stories in recent months, particularly in China. Leju Holdings (LEJU), with a market capitalization of nearly $2 billion, is holding up relatively well despite fears of a slowdown in the Chinese real estate market. The provider of real estate services, a spinoff of E-House Holdings (EJ), went public in April at 10. In May, Leju reported a 97% jump in Q1 sales to $78.5 million.
