Since 2009, a "quantitative fund" craze has quietly set off. China Shipping Fund, Changsheng Fund, China Everbright Prudential and Guo Fu Fund have all launched their own quantitative products, and the Guo Fu 300 Enhanced Fund being launched in Guo Fu is the first enhanced index fund, because the concept of quantification has been introduced. With regard to quantitative funds, the international capital market, especially the American market, has made considerable progress and formed a considerable scale. Through mathematical statistics analysis, the quantitative fund selects those securities whose future returns may exceed the benchmark to invest in order to obtain the returns beyond the index fund. Different from ordinary funds, quantitative funds mainly adopt quantitative investment strategies for portfolio management. Generally speaking, the strategies adopted by quantitative funds are: quantitative stock selection, quantitative timing, stock index futures arbitrage, commodity futures arbitrage, statistical arbitrage, option arbitrage, algorithmic trading and asset allocation.
