Recognition On The Dynamic Investment Strategies Of The Fund Based On Financial Network

Since the 1990 s,a vast literature on the application of network to finance markets. Most of these objects of literature mainly focus on stock market, foreign exchange market, etc. However, only a few studies touch the fields of fund network and fund strategy identification. There exists the evident discrepancy between the actual and stated investment strategy. How can the investment strategy be identified by using financial network has important practical significances.This research construct financial network model to explain the evident discrepancy between the actual and stated investment strategy. By using different periods, time scale, time interval of fund network, we identify the dynamic evolution of fund actual strategy. At the first, we build three different periods of 2005-2013 actual strategy fund networks to reflect the information of financial markets. And then, study the hierarchical structure of different timescale actual strategy fund networks to help us realize the actual fund strategy change. Finally we build the actual strategy network with time evolution to dynamic identify the characteristics of actual strategy in 2013, and study the transfer problems of fund actual strategy.By building different types of fund network models, analyzing the topology characteristics of actual strategy fund network, mining the change of the actual financial market funds strategy, which can help investors recognize the real strategy and reasonable fund portfolio.
