Abstract:

The complex structure and diverse imformation of stock markets make stock movement prediction extremely challenging. However, most of the existing studies treat each stock as an individual or use graph structures to model complex higher-order relationships in stock markets, without considering the hierarchy and dynamics among stocks, industries and markets. Aiming at the above problems, a Dynamic Macro Memory Network (DMMN) was proposed, and price movement prediction was performed for multiple stocks simultaneously based on DMMN. In this method, the market macro-environmental information was modeled by the hierarchies of “stock-industry-market”, and long-term dependences of this information on time series were captured. Then, the market macro-environmental information was integrated with stock micro-characteristic information dynamically to enhance the ability of each stock to perceive the overall state of the market and capture the interdependences among stocks, industries, and markets indirectly. Experimental results on the collected CSI300 dataset show that compared with stock prediction methods based on Attentive Long Short-Term Memory (ALSTM) network, GCN-LSTM (Graph Convolutional Network with Long Short-Term Memory), Convolutional Neural Network (CNN) and other models, the DMMN-based method achieves better results in F1-score and Sharpe ratio, which are improved by 4.87% and 31.90% respectively compared with ALSTM, the best model among all comparison methods. This indicates that DMMN has better prediction performance and better practicability.

摘要:

股票市场结构复杂、信息多样,股票趋势预测极具挑战性。但现有研究大都把每只股票当作一个独立的个体,或者使用图结构对股票市场中复杂的高阶关系进行建模,缺少对股票、行业、市场三者间相互影响的层次性和动态性考量。针对上述问题,提出一种动态宏观记忆网络(DMMN),并基于DMMN同时对多只股票进行价格趋势预测。该方法按照“股票-行业-市场”的层次对市场宏观环境信息进行建模,并捕获这些信息在时序上的长期依赖;然后将市场宏观环境信息与股票微观特征信息动态融合,在增强个股对市场整体情况的感知能力的同时间接捕获到股票、行业、市场三者间的相互依赖。在收集的CSI300数据集上得到的实验结果表明,相较于基于注意力长短期记忆(ALSTM)网络、添加了图卷积的LSTM网络(GCN-LSTM)、卷积神经网络(CNN)等模型的股票预测方法,基于DMMN的方法在F1分数、夏普比率上都取得了更好的效果,和表现最优的对比方法ALSTM相比分别提升了4.87%和31.90%,这表明DMMN在具备较好预测性能的同时还具备更好的实用价值。
