| With our modern financial innovation and the rapid development of the fund industry, and with the collective,flexible and risk diversification characteristics, fund area had been chosen by more and more investors of all ages. Fund industry has been one of the four pillars of banking, securities and insurance industry, and has become a modern financial system, Rapid increase in the range of funds, making the Fund investment style of an important and urgent issue. However, the current academic research on securities investment funds remain in the perspective of most of the direct evaluation of fund performance, investment style of the fund very few combine the two studies is even more pitiful, style adjusted performance research is still quite immature. Despite the growing number of fund companies declare that their fund's investment style - the name of style in the recruitment of the book to help investors make choose, fund style pre-and post the resulting inconsistency, that style "drift" phenomenon. Therefore, the Fund's actual investment style of the identification becomes more and more important, the style-adjusted fund performance research become a necessity.As this innovation, on the one hand, in the empirical method point of view, this article uses Dynamic and Static methods of combining comprehensive evidence. The Static method means investment style of research conducted only once during the whole period to the study, and the Dynamic method means the entire study period be divided into more than one study period to carry out estimation. To this article, the article firstly conducted the investment style from the entire period as the Static method and then divided the whole period into two scripts and six rolling period as the Dynamic period. Compared this two parts to determine the Fund's actual investment style. In addition, in the research point of view, this article chose open-end funds and closed-end funds to take into account, and compared the style of drifting style of the two different types of funds; What's more, with the basis of the drifting style, the study occurred in the difference of the fund that having changed its styles and that of being never changed ,with the result ,we can find that whether style drift is rational. In other words, with horizontal and vertical angles of the comprehensive analysis, the conclusion will take more accurate and comprehensive performance of the fund style drift and the issues affecting the inspection.With the research and innovation based on the above background, the concrete evidence of this article can be divided into two parts:Firstly, after introducing the style of fund style classification and identification of relevant theoretical model, the article divided fund style by the value / growth and scale factor. Then we chose the Sharpe Model, which based on the multi-factor regression model, to verify the actual style of the open and closed-end funds. Among them, the sample selected for the May 31, 2006 listing of 49 open-end funds and 27 closed-end funds, and for criteria for the classification of Static dynamic, this article chose June 1, 2006 to June 30, 2009 as the whole period of study, and as the Dynamic empirical, we divided the entire period into Bull and Bear periods and six rolling periods as two different angles. Through different periods for different categories of funds investment style under the actual test, compared with the funds obtained the name of style drift of their situation , we have the following conclusions:(1) Static Analysis on the samples funds for open-and closed-end funds, we concluded that two funds have occurred in the whole range of style drift and the actual investment style of each sample were a convergence. Coefficient of determination similar but mean different volatility and drift of both the extent of the investment ratio is not the same.(2)In the Bull and Bear periods, two kinds of style drift both occurred, and style drift of different types of fund in the same direction, with the apparent convergence. But the open-end fund, whether in what circumstances, the drift level higher than the closed-end funds. And two in the investment ratio and the coefficient of determination is not in the same.(3) Samples of the Fund through the static and dynamic results of the horizontal comparison, we find that the whole time interval does not occur even if the drift of the Fund in the dynamic study period (in Bull and Bear periods) will also occur under the drift style. Only few funds keep the same strategy in different periods.Secondly, based on the conclusion above, the article chose the Gruber Model and M 2Model to verify the achievements of different kinds of styles Funds in the entire study period (static) and the bull and bear markets (dynamic), and the following conclusions are:(1) In the entire study period, the open-end fund style drift occurs in the mutual fund performance is better than stick-style fund performance, and closed-end funds in the stick style better fund performance, that is, different types of fund of fund performance drift were different. Two styles of fund performance is higher than the market benchmark risk-free rate of return, the Fund effective style of convergence.(2) Fund in the Bull and Bear of the sample during the empirical test shows that different types of style drift in different environments affect the performance of the Fund are different. In general, open-end fund style drift gains than closed-end funds, the specific performance of the open-end fund style drift during the bull market fund performance is better during the bear market style drift is invalid, the same time, closed-end funds are style drift not more than stick-style fund performance.(3) In the dynamic study period (Bull and Bear), two styles are made exceed the Fund benchmark rate of return earned more than yield, and the style of convergence and not the same fund in a bear market efficiency performance is superior fund performance during the bull market . Furthermore, the fund is not like the style of convergence of the conclusions of other scholars have said the fund manager or fund non-rational to follow suit immature market. On the contrary, the actual style of convergence is the fund manager of the fund value / growth and market initiative in select categories.Finally, we have the comprehensive suggestion: to the fund manager concerned, when they make investment decision, they should consider the characteristics of different types of funds, combined with market conditions, and then choose the most suitable market fund investment styles; and to the regulatory agencies, as style drift to the general is to adapt the behavior of the market and therefore, they should not blindly be defined as the performance of fund managers under pressure to selfish behavior, on the contrary, they should be combined with a variety of fund's performance classification regulation, through the development of relevant legal system to regulate the overall market environment, use the market to guide our own reaction to be more standard and mature. |
