  • 用混合模型融合结构化数据与文本信息,实现概率化预测。
  • 净利润预测MAPE仅3.03%,95%置信区间窄,风险收益比佳。
  • 适合关注新兴市场风险的金融机构和量化分析师参考。

面对日益加剧的金融不确定性和市场复杂性,本文提出一种新型风险感知金融预测框架,结合先进机器学习技术与直觉模糊多准则决策方法(MCDM)。该框架针对土耳其股市BIST 100指数,以一家大型国防公司为案例验证,融合结构化财务数据、非结构化文本数据及宏观经济指标,提升预测准确性和鲁棒性。采用极端梯度提升(XGBoost)、长短期记忆网络(LSTM)和图神经网络(GNN)等混合模型,输出带不确定性量化的概率预测。实证结果表明,净利润平均绝对百分比误差(MAPE)仅为3.03%,关键财务指标的95%置信区间狭窄。风险分析显示,夏普比率1.25,索提诺比率1.80,表明下行波动低且在市场波动中表现稳健。敏感性分析表明,通胀、利率、情绪和汇率变化对关键指标预测影响显著。通过熵权法、平均解距离评估(EDAS)与最优妥协解排序法(MARCOS)联合的直觉模糊MCDM方法,表格式数据学习网络(TabNet)表现最佳,被确定为最适部署模型。研究强调,在新兴市场中整合机器学习、风险量化与模糊多准则决策的重要性。

原文摘要 · Abstract (English)

In the face of increasing financial uncertainty and market complexity, this study presents a novel risk-aware financial forecasting framework that integrates advanced machine learning techniques with intuitionistic fuzzy multi-criteria decision-making (MCDM). Tailored to the BIST 100 index and validated through a case study of a major defense company in Türkiye, the framework fuses structured financial data, unstructured text data, and macroeconomic indicators to enhance predictive accuracy and robustness. It incorporates a hybrid suite of models, including extreme gradient boosting (XGBoost), long short-term memory (LSTM) network, graph neural network (GNN), to deliver probabilistic forecasts with quantified uncertainty. The empirical results demonstrate high forecasting accuracy, with a net profit mean absolute percentage error (MAPE) of 3.03% and narrow 95% confidence intervals for key financial indicators. The risk-aware analysis indicates a favorable risk-return profile, with a Sharpe ratio of 1.25 and a higher Sortino ratio of 1.80, suggesting relatively low downside volatility and robust performance under market fluctuations. Sensitivity analysis shows that the key financial indicator predictions are highly sensitive to variations of inflation, interest rates, sentiment, and exchange rates. Additionally, using an intuitionistic fuzzy MCDM approach, combining entropy weighting, evaluation based on distance from the average solution (EDAS), and the measurement of alternatives and ranking according to compromise solution (MARCOS) methods, the tabular data learning network (TabNet) outperforms the other models and is identified as the most suitable candidate for deployment. Overall, the findings of this work highlight the importance of integrating advanced machine learning, risk quantification, and fuzzy MCDM methodologies in financial forecasting, particularly in emerging markets.
