Before revision:  In experiments, we use our model in several randomly selected portfolios which include CSI300 that represents the market's rate of return and the randomly selected constituents of CSI500. The experimental results show that no matter what stocks we select in our portfolios, we can always get a higher return than the market itself, namely we can get artificial intelligence through deep reinforcement learning to defeat market .
