  According to data provider Preqin statistics, the first half of this year, computer-generated investment strategy, that is, jargon called "system strategy" rate of return of 3.17%. In contrast, the traditional discretionary strategy (Discretionary strategies) the rate of return of 5.99%, almost twice the former. The results are calculated after deducting the transaction costs.
