Quantitative AI finance, integrating artificial intelligence technology with quantitative investment methods, is reshaping modern investment strategies. This paper explores the innovations and practices of quantitative AI in investment strategy from three perspectives: reinforcement learning-driven dynamic asset allocation, multimodal data integration and analysis, and automated factor engineering optimization. Through reinforcement learning models, strategies gain flexibility in real-time asset allocation adjustments; multimodal data integration broadens the depth and breadth of information acquisition; automated factor engineering significantly enhances the efficiency and accuracy of factor discovery and optimization. These technological innovations effectively address the lag and singularity of traditional investment strategies, significantly improving their forward-looking nature and risk resistance. Furthermore, the article analyzes challenges and future directions brought by technological advancements, highlighting areas for improvement in data quality, algorithm transparency, and market regulation. By deeply integrating technology and data, quantitative AI finance paves new avenues for innovation in investment strategies.
