Most existing approaches to this task employ an attention mechanism that primarily relies on the information extracted from input features but fails to consider the other important factors (e.g. trading volume and position), which can potentially enhance these attention-based approaches. Motivated by the observation, we extend the attention mechanism with features needed for stock performance prediction in this paper. Specifically, we propose a volume-aware positional attention-based recurrent neural network (VPA-RNN) for this task. First, we propose a generic method of adding position awareness to the attention mechanism. Next, the trading volume is incorporated into the original attention distribution to form a revised distribution. To evaluate the effectiveness of VPA-RNN, we collected real stock market data for stock indexes S&P 500 and DJIA, and the experimental results show that the proposed VPA-RNN can significantly outperform several existing highly competitive methods. <\/jats:p>","DOI":"10.1142\/s0218194021400222","type":"journal-article","created":{"date-parts":[[2022,1,25]],"date-time":"2022-01-25T09:01:56Z","timestamp":1643101316000},"page":"1783-1801","source":"Crossref","is-referenced-by-count":1,"title":["Forecasting Stock Index Using a Volume-Aware Positional Attention-Based Recurrent Neural Network"],"prefix":"10.1142","volume":"31","author":[{"given":"Xinpeng","family":"Yu","sequence":"first","affiliation":[{"name":"Agricultural Bank of China, Beijing, P.
