Abstract
Stock price forecasting is an important topic in financial time series analysis. Traditional time series models have limitations in processing nonlinear financial data, and deep learning models show application potential due to their strong feature learning capabilities. In this study, a long short-term memory network and an autoregressive comprehensive moving average model are constructed to systematically compare their performance differences in stock price prediction. The study adopts a unified technical index system and a multi-dimensional evaluation framework to evaluate the performance of the model from three dimensions: prediction accuracy, direction judgment and generalization ability. The empirical results show that the deep learning model has significant advantages in capturing the nonlinear characteristics of stock prices, and is better than the traditional time series method in all evaluation indicators. It is manifested in higher prediction accuracy, better trend judgment ability, and stronger out-of-sample generalization performance. The research results confirm the effectiveness of deep learning in financial time series analysis and provide a methodological reference for quantitative investment strategies. The comparative analysis framework established by this study can be extended to other financial prediction scenarios and has high practical application value.
