📄 Abstract - Predicting Stock Price Direction on Earnings Announcement Days using Multi-modal Deep Learning

Predicting stock price movements during Earnings Announcements (EAs) is a significant challenge due to market noise and high-impact price discontinuities. In this study, we evaluate whether pre-announcement news sentiment, firm fundamentals, and recent market dynamics jointly predict the directional price movement of equities on EA days. We construct a multi-modal feature space combining 15 fundamental metrics, 3 price-based technical indicators and sentiment scores derived from financial news articles processed using FinBERT. We compare a Long Short-Term Memory (LSTM) network and a Transformer-based architecture against a logistic regression baseline, and further assess all models with and without sentiment features to quantify their incremental value. Our results indicate that while the LSTM demonstrates higher precision through a conservative safe-bet strategy, the Transformer model exhibits superior sensitivity in identifying volatile movements, achieving a higher macro F1-score, with ablation experiments showing a consistent benefit from incorporating news sentiment.

基于多模态深度学习预测财报发布日的股票价格走势 / Predicting Stock Price Direction on Earnings Announcement Days using Multi-modal Deep Learning


1️⃣ 一句话总结

本研究通过融合公司财务指标、技术指标和新闻情感分析的多模态数据,比较了LSTM和Transformer等深度学习模型与逻辑回归模型在预测财报发布日股票涨跌方向上的表现,发现新闻情感信息能稳定提升各模型的预测能力,其中Transformer模型对股价剧烈波动更为敏感,而LSTM模型则倾向于给出更保守但准确率更高的预测。
