    A Study of the Effect of Relative Performance on the Risk-taking Behavior of Mutual Funds
    WANG Ming-hao, CHEN Zhong, CAI Xiao-yu
    2004, (5):  1-5. 
    Abstract ( 1849 )   PDF (2254KB) ( 1876 )   Save
    In this paper,in order to theoretically study the effect of relative performance on the risk-taking be-havior of mutual funds,we view the mutual fund market as a series of tournaments and develop a game model.In the model,two funds with unequal midyear performances compete for new cash inflows,accordingly for more compensation at the end of year,when the tournament is ended.Contrary to people’s institution,we find that the fund with better midyear performance is more likely to choose a higher level of risk of protfolio than the fund with worse midyear performance.Moreover,the higher the midyear performance gap is,or the higher the risk as-set’s return or the lower risk asset’s volatility is,the larger the probability of choosing a higher level of risk of protfolio by the fund with better midyear performance;accordingly,the lower the probability of choosing a higher level of risk of protfolio by the fund with worse midyear performance.At last,according to the principle of game and the theory of behavior finance,we explain the results.

    This paper proposed the method of applying artificial neural Networks to evaluate the grading of stock.At first,we establish the criteria system to evaluate the grading of stock,and then evaluate the stock index of training sample in ANN.Second,optimize the result based on information spread and use the optimized result to train neural networks with the back propagation.When arriving the necessary precision,the training will be stopped.The artificial neural networks may evaluate the grading of stock.In the end of this paper,we give a practical example and the detailed calculation steps,to explain this method and the grading results of stock.Using this method to evaluate the grading of stock will be helpful to reduce the influences of subjectivity and the market changes.

    2004, (5):  12-16. 
    Abstract ( 1929 )   PDF (1422KB) ( 1301 )   Save
    According to modern capital structure theory and option theory,designating that the price of assets is less than debt received by listed firms as the indicator of financial distress(FD),the paper designs the Expected Default Frequency(EDF)model using publicly available financial data and the information index of the capital market,i.e.price of the stock.The model can dynamically predict FD in listed firms and overcome the weakness of statistics models.

    Abstract ( 1971 )   PDF (2167KB) ( 1834 )   Save
    The problem of choosing a substitute for the market portfolio of risk assets in CAPM is discussed.It is pointed out that only the market index portfolio formed by arithmetic average index can properly replace the real market portfolio.By selecting s representatives of risk assets,the conditions of choosing a valid assets portfolio from the s representatives as a substitute for the real market protfolio are obtained.The new and comparatively complete proofs in which the two kinds of valid forward positions of asset portfolios are tangent have been shown.

    This paper systematically compared A Share of Shanghai and Shenzhen in short-term behavior after overreaction using the data from Jan.1997to Oct,2003.The empirical study reveals that both Shanghai Stock Market and Shenzhen have overreaction in negative price shocks in short-term windows.But in positive price shocks there is only momentum effect.Our analysis highlights that there exists"March effects",not the common"January effects".The regression results indicate that,for both Shanghai and Shenzhen,the cumulative abnormal returns are not always strongly related to the levels of the shocks.
