The majority believes that the time is ripe for stock index futures. Based on the analysis of game model, it is the aggravating competition and stock market's depression that make securities dealers and institutional investors badly in need of the short selling tools by which they may get sudden huge profits, thus the theory of "ripe opportunity" comes into being. In fact, if good deals of problems in China's stock market aren't resolved, the stock index futures should not be brought out. It is a long-term task in China's stock market development.
