    摘要: 資產配置一直都是投資市場中重要的課題，要如何做好投資組合管理，各家基金公司都有各自的方法，而隨著金融科技(Financial Technology, Fintech)的迅速地發展下，越來越多資產管理公司運用機器學習或深度學習進行資產配置，像是國外的資產管理公司就有推出AI智能選股的基金，而台灣也在這個浪潮下，快速地往這方面發展。隨著金融商品發展，境內組合型基金已經從兩年多前的兩百多檔，成長到現在的三百多檔，因此，組合型基金成為投資人新的投資工具，投資人如果是購買組合型基金，就相當於把資金分散投資在多檔基金，自動就達成資產配置的效果。
    因此，本研究欲導入強化學習來建構組合型基金的資產配置，透過強化學習來決定投資組合中每一檔基金的權重，進而達到最佳策略，而強化學習的獎勵機制正好與資產的報酬不謀而合，所以非常合適。本研究運用強化學習建構了三個子模型，並與指標進行比較，研究結果發現，年化夏普值平均提升了十五個百分點，不僅顯示了資產配置對投資組合的重要性，也顯示強化學習運用在組合型基金資產配置的可行性。
    Asset allocation has always been an important issue in the investment market. Each investment company has its own key to do a good job in portfolio management . with the rapid development of financial technology (Financial Technology, Fintech), more and more asset management companies use machine learning or deep learning for asset allocation. For example, foreign asset management companies launch funds based on AI selection and Taiwan is also rapidly developing in this direction . With the development of financial commodities, domestic Fund of funds have grown from two hundred to three hundred. Therefore, Fund of funds have become a new investment tool for investors.
    Therefore, this study wants to introduce reinforcement learning to construct the asset allocation of Fund of funds. By using reinforcement learning, we can determine the weight of each fund in the portfolio to achieve the optimal allocation and the reward in reinforcement learning coincides with the return of assets. This study uses reinforcement learning to construct three sub-models and compare them with benchmark. The results show that the annualized Sharpe ratio has increased by an average of fifteen percentage, which not only shows the importance of asset allocation to the portfolio, but also shows that feasibility in Fund of funds allocation by using reinforcement learning.
