This study aimed to develop an artificial intelligence-based investment decision-support model for portfolio management under severe market volatility, with emphasis on risk prediction, adaptive asset allocation, tail-risk control, and explainability of algorithmic investment decisions. This study adopted a qualitative exploratory design. The participants consisted of 22 experts from Tehran, including portfolio managers, investment analysts, financial risk specialists, fintech professionals, capital market experts, and university academics. Participants were selected using purposive and criterion-based sampling. Data were collected through semi-structured interviews and the interview process continued until theoretical saturation was achieved. Saturation occurred at the nineteenth interview, followed by three confirmatory interviews to ensure the stability and adequacy of the extracted categories. Data were analyzed using thematic analysis with the support of NVivo software. Trustworthiness was enhanced through member checking, peer review, audit trail, and continuous comparison of codes and categories. The analysis resulted in five main categories: “multi-source data integration and market regime detection,” “intelligent prediction of risk and return under severe volatility,” “adaptive portfolio optimization and tail-risk control,” “explainability, trust, and human oversight,” and “data governance, operational infrastructure, and algorithmic error control.” The findings indicated that an effective AI-based investment decision-support model should not be limited to price forecasting. Rather, it should operate as a multi-layered system capable of processing historical market data, behavioral data, macroeconomic indicators, news, market sentiment, liquidity conditions, and investor-specific risk constraints simultaneously. The results suggest that an AI-based investment decision-support system is effective under turbulent market conditions only when it balances algorithmic accuracy, interpretability, risk control, adaptability to market regime shifts, and human judgment. The proposed model can serve as a practical framework for asset management companies, investment funds, brokerage firms, and financial institutions seeking to design intelligent portfolio management systems in highly volatile markets.
