In the financial field, constructing efficient investment portfolios is a focal point of research, encompassing asset selection and optimization allocation. With advancements in Large Language Models (LLMs), generative Artificial Intelligence (AI) tools have showcased capabilities never seen before. However, black-box nature these renders their outputs difficult to interpret directly, often necessitating iterative fine-tuning align with users' expected outcomes. This study presents structured prompt framework specifically designed for stock selection, aiming provide direct interpretable stock-selecting investors various levels. By creating representative scenarios combining them into different cases experimentation, we can explore how construction prompts influences responses generated by AI tools. Additionally, this paper proposes novel algorithm that combines Nonlinear-Activated Beetle Antennae Search strategy Egret Swarm Optimization Algorithm (NBESOA) address Mean-Variance Portfolio Selection problem Transaction Costs Cardinality Constraints (MVPS-TCCC), utilizing real market data construct based on recommendations. Simulation results indicate that, compared other algorithms, NBESOA prefers optimizing portfolio configurations achieve highest Sharpe Ratio strictest constraints, bringing outcomes closer portfolio's frontier.
