# 深度学习因子月报DL_EM_Dynamic 因子三月实现超额收益6.6％               2025年04月10日
## 1 深度学习因子近期表现概览
## 2各因子介绍和指数增强组合表现
### 2.1 DL_EM_Dynamic 因子
### 2.2 Meta_RiskControl 因子
#### 回顾历史我们发现，深度学习因子的回撤大都发生在某些风格因子变化较快的时刻。
#### 鉴于元增量学习具有对于市场变化快速适应的能力，我们可以将这一框架与模型进行结合。
#### 组合构建：
### 2.3 Meta_Master 因子
#### 将市场信息纳入模型中进行训练，相比Transformer 收益预测模型可以获得稳定提升。
#### 进一步利用深度风险模型计算新的市场状态，并替换损失函数和训练框架，获得了进一步提升。
#### 组合构建：
### 2.4深度学习可转债因子
#### 将深度学习应用于可转债投资，相对传统量化可转债投资策略收益得到显著提升。
#### 深度学习可转债因子最近表现尚可。
#### 各类型转债2025年3月超额收益有所差异。
#### 深度学习可转债因子继续偏好高评级转债，最新截面各类型转债top50打分数据如下：
## 3 风险提示
### 1）量化结论基于历史统计，如未来环境发生变化存在失效可能。
### 2）选股模型结论不构成投资建议，实际投资还需要考虑外部市场环境、估值等因素并进一步评估。
