QuantaAlpha: An Evolutionary Framework for LLM-Driven Alpha Mining
QuantaAlpha is an evolutionary alpha mining framework that leverages large language models (LLMs) to discover robust and interpretable alpha factors in financial markets. It addresses limitations of existing agentic systems by using a 'trajectory-level self-evolution' approach, where each end-to-end mining run is treated as a trajectory. Factors are improved through mutation (targeted revisions) and crossover (recombining high-reward segments), ensuring semantic consistency and controlling complexity/redundancy. Experiments on CSI 300 show superior performance in predictive power, annualized returns, and lower maximum drawdown compared to strong baselines like AlphaAgent and RD-Agent. Critically, the factors demonstrate strong robustness and transferability to other markets (CSI 500 and S&P 500), indicating their effectiveness under market distribution shifts. The framework's ability to maintain factor diversity and adapt to regime changes through structured evolution is a key differentiator.

QuantaAlpha treats alpha mining as an agentic workflow, evolving complete research trajectories rather than relying on unconstrained re-generation from noisy feedback. It includes Diversified Planning Initialization, Controllable Factor Construction with semantic consistency and complexity controls, and Factor Evaluation via standardized backtesting. The core innovation lies in its Self-Evolution Strategy, which uses trajectory-level Mutation and Crossover to improve factor quality iteratively. Mutation performs targeted revision of suboptimal steps, while Crossover recombines complementary high-reward segments from parent trajectories to reuse effective patterns and create novel market dynamics.
QuantaAlpha achieves superior performance on CSI 300, with an IC of 0.0472 and ARR of 4.68%, outperforming AlphaAgent and RD-Agent significantly. Factors demonstrate strong transferability to CSI 500 (40.28% cumulative excess return) and S&P 500 (19.1% cumulative excess return) over four years, indicating robustness to market distribution shifts. Ablation studies confirm the critical role of diversified planning, mutation (primary driver of exploration and repair), and crossover (improving efficiency and stability via pattern reuse). The framework's controls for consistency, complexity, and redundancy are all essential for robust factor generation.
QuantaAlpha introduces a novel paradigm for alpha discovery in high-noise, non-stationary domains by focusing on controllable, traceable, and diversity-preserving agentic evolution. Its ability to generate interpretable and generalizable factors addresses key challenges in quantitative finance, offering a more stable and robust approach to identifying predictive signals in dynamic markets. This framework's principles of trajectory-level evolution and structured refinement could be applied to other complex discovery problems beyond finance.

Case Study: Institutional Momentum Score Factor
Evolution of Institutional_Momentum_Score_20D
This factor demonstrates QuantaAlpha's ability to synthesize complex market hypotheses through crossover. It combines insights from parent trajectories (one focusing on fragile retail-driven momentum, the other on sustainable institutional momentum) to create a 'regime-aware dual-source momentum factor'. The factor's expression combines correlation between price returns and volume changes with average intraday return patterns, capturing institutional activity and improving predictability. This illustrates the framework's capacity for structured, hypothesis-driven factor refinement.
- Dual-Source Integration: Combines retail and institutional momentum signals.
- Regime Awareness: Dynamically weights signals based on market volatility for superior predictive returns.
- Enhanced Predictability: Significantly improved annualized excess return and predictive metrics post-crossover.
- Structured Refinement: LLM generates new hypotheses by integrating complementary insights, not just averaging expressions.
