报告摘要
中国A股风格因子月报总结
核心内容概述
本报告总结了2017年9月中国A股市场的风格因子表现与市场投资环境的变化。整体来看,市场投资环境有所改善,个股收益率成对相关系数继续走低,但横截面波动率有所回升,表明市场中股票价格更多由个股信息驱动。此外,高质量因子表现强势,企业盈利水平有所改善,预计将在11月跑赢市场。
主要观点
- 市场投资环境改善:A股市场整体呈现投资环境改善的迹象,股票价格的共振趋势较弱,说明市场波动主要来源于个股信息而非宏观因素。
- 市场估值水平:截至2017年9月底,A股整体预测市盈率略高于过去十年平均水平,新经济与旧经济之间的估值差距扩大,但其他估值差保持不变。
- 风格因子表现:
- 高质量因子(High ROE、High ROIC、Low Debt/Equity等)表现强势,过去一个月显著跑赢市场。
- 低风险因子(Low Beta、Low Volatility等)也表现占优,市场宽度增加为选股提供更多机会。
- 成长因子(High Forecast EPS Growth、High Historical EPS Growth)表现分化,部分因子跑赢市场,部分则表现不佳。
- 动量因子(High Earnings Revisions、High Previous Performance)表现波动,部分因子在短期表现良好,但长期表现不一。
- 规模因子(Small Caps、Large Caps)表现差异较大,小盘股整体表现优于大盘股。
