英文摘要:
Predicting the price correlation of two assets for future time periods is important in portfolio optimization. We apply LSTM recurrent neural networks (RNN) in predicting the stock price correlation coefficient of two individual stocks. RNNs are competent in understanding temporal dependencies. The use of LSTM cells further enhances its long term predictive properties. To encompass both linearity and nonlinearity in the model, we adopt the ARIMA model as well. The ARIMA model filters linear tendencies in the data and passes on the residual value to the LSTM model. The ARIMA LSTM hybrid model is tested against other traditional predictive financial models such as the full historical model, constant correlation model, single index model and the multi group model. In our empirical study, the predictive ability of the ARIMA-LSTM model turned out superior to all other financial models by a significant scale. Our work implies that it is worth considering the ARIMA LSTM model to forecast correlation coefficient for portfolio optimization.

中文摘要:
预测未来时期两种资产的价格相关性在投资组合优化中非常重要。我们应用LSTM递归神经网络(RNN)预测两支股票的股价相关系数。RNN能够理解时间依赖关系。LSTM单元的使用进一步增强了其长期预测特性。为了在模型中同时包含线性和非线性,我们也采用了ARIMA模型。ARIMA模型过滤数据中的线性趋势,并将残值传递给LSTM模型。ARIMA LSTM混合模型与其他传统预测财务模型(如全历史模型、常数相关模型、单指数模型和多组模型)进行了对比测试。在我们的实证研究中,ARIMA-LSTM模型的预测能力在很大程度上优于所有其他金融模型。我们的工作表明,ARIMA LSTM模型用于预测投资组合优化的相关系数是值得考虑的。
