By next year, the Chinese internal security market is set to be worth $33-billion. Several of the larger Chinese players in the field have recently taken their stocks public on U.S. exchanges, hoping to cash in the fact that, in volatile times, security and defense stocks are seen as the safe bets. China Information Security Technology, for instance, is now listed on the NASDAQ and China Security and Surveillance is on the NYSE. A small clique of U.S. hedge funds has been floating these ventures, investing more than $150-million in the past two years. The returns have been striking. Between October 2006 and October 2007, China Security and Surveillance's stock went up 306 percent.
