To RPC, the fluidity was usually a key index, because it directly reflected the work-ability. The effect factors were complex, however, the quantity relation between the RPC fluidity and its effect factors could not be expressed with a uniform numeric formula. There was no effective method for this problem at present. In accordance, a numeric method which used for controlling the RPC fluidity was advanced. The neural network model based on genetic algorithm was introduced for a aptitude method consequently.

Among them the influence factor of the stock is mainly: Fund manager select stocks ability, investment style and ability to deal with the accident, national macroeconomy situation factor, the market value of stock usually have the direct influence to the fund net value; To bond part in the net value of the fund, interest rate and the investment ability of fund manager concerns the value level of this part of assets directly, because the securities regulator of our country has made the regulation to the proportion of the fund investment bond besides this, so, this proportion will restrict fund managers investment on the bond either, thus exercise an influence on some value of bond ; Besides stock and two bond, to another important component in the net value composition --The cash, we will all sum up its factor of exerting an influence for the mobile risk factor, namely the risk as a reasult of the exility of cash.
其中股票方面的影响因素主要是:基金经理的选股能力、投资风格和选时能力以及大盘走势与突发事件、国家宏观经济形势因素,股票市值通常受到这些因素的直接影响;对于基金净值中的债券部分来说,利率和基金经理的投资能力直接关系到这部分资产的价值高低,除此以外由于我国证券监管机构对基金投资债券的比例作了规定,因此,该比例也会制约基金经理在债券上的投资,从而对债券部分价值发生影响;除了股票和债券两部分以外,对于净值构成中的另一重要组成部分——现金,我们将对其产生影响的因素全部归纳为流动性风险因素,即由于现金的稀缺而导致的风险。
