Abstract

In the stock market, stock price forecasting is important for investors' decisions. Due to the nonlinearity, high noise, and strong temporal variability of stock price data, tradi-tional methods have shortcomings in forecasting tasks. Since based on the structure and function of recurrent neural networks, the Long Short Term Memory (LSTM) model has stronger analytical capabilities for this type of time series data. In stock prices predic-tion, it is important to consider external factors as well as network structures within shareholdings. In this paper,the directed holding network will be vectorized using the LINE algorithm, and four A-share listed companies will be analyzed and compared using three distinct stock price datasets. The study indicates that companies' stock prices are significantly impacted by the relationships between shareholdings and the fluctua-tions in related company stock prices from the perspective of network topology, leading to risk spreads within the shareholding network. Additionally, category characteristics can serve as effective assessment features.
