This paper studies the Level, Slope, and Curve factor model under different tests in the Chinese stock market. Empirical asset pricing tests reveal that the slope factor in the model represents either reversal or momentum effect for the Chinese stocks. Further tests on individual stocks demonstrate that the Level, Slope, and Curve model using effective predictor variables outperforms other common factor models, thus a filter in virtue of multiple hypothesis testing is designed to identify the effective predictor variables. In the filter models, the cross-section anomaly factors perform better than the time-series anomaly factors under different tests, and trading frictions, momentum, and growth categories are potential drivers of Chinese stock returns.

In this paper, we propose a new approach to test the presence of GARCH Effects of China stock market. Our method is based on Maximal Overlap Discrect Wavelet Transform (MODWT)that provides a natural platform to investigate the volatility behavior at different time scales without losing any information.The empirical results show that GARCH effects are more significant at short time horizons as compared to long. Furthermore, when compared the modeling results of GARCH-t with that of EGARCH-t, it yields very higher effectiveness to capture the leverage effect of financial time series at relavant time scales.

摘要：作者对实际使用的对冲模型提出研究，在本文中建立了一个在指数.指数期货.指数期权上的进行无套利对冲的前沿模型，揭开了对冲基金使用数量模型神秘的面纱。通过比较从市场指数和指数期货中估计得出的风险中性密度函数与从隐含在指数期权市场的风险中性密度函数，发现对冲机会，设计对冲交易策略。我们这里采用的估计方法为非参数方法,是对BS模型的拓展。 Abstract: In this paper, the authors make a research on the field of hedge model, after the investigation of some hedge funds in U.S. ,we establish a frontier no-arbitrage hedge model for index.index futures and index options. We compare the risk neutral density estimated from cross section of index market to the risk neutral density inferred from the time series of index and index future markets. The methods we used are nonparametric method and hypothesis test. We can find the arbitrage opportunity and design the hedge trading strategy.
