股指期货轮动与套利（一）：框架构建与因子检验

研究院 量化组 摘要 研究员 A 股市场大小盘风格的频繁轮动，是当前投资框架下最具挑战性的课题之一。本报告从宏观、基本面、资金、及微观结构四大维度出发，构建了覆盖多视角的择时因子观测体系。通过对 IF 与 IC 历史数据的回测，逐一检验了各维度指标在风格轮动中的独立择时效果，发现短周期动量、基差以及利率因子在单因子层面展现了较为突出的超额收益贡献。然而，回测结果同样揭示出单因子策略“阶段性有效、长期受噪音干扰”的局限性。基于此，本篇报告为多因子综合研判奠定了基础，后续报告将继续探索如何将优势指标组合为更稳健的轮动系统，以应对风格切换的不确定性。 高天越0755-23887993gaotianyue@htfc.com从业资格号：F3055799投资咨询号：Z0016156 李逸资0755-23887993liyizi@htfc.com从业资格号：F03105861投资咨询号：Z0021365 核心观点 李光庭0755-23887993liguangting@htfc.com从业资格号：F03108562投资咨询号：Z0021506 1）短周期动量和基差因子在 IF、IC 择时轮动上效果较好，年化超额分别约为 7.36%、5.11%，日度准确率约为 54.06%、51.23%。 2）总体来看单因子择时能力体现出参差不齐、阶段性有效的特征，因此后续报告将多因子组合作为优化方向之一，探讨多因子框架在轮动、跨品种套利上的有效性。 黄煦然0755-23887993huangxuran@htfc.com从业资格号：F03130959投资咨询号：Z0023955 联系人 林炜栋0755-23887993linweidong@htfc.com从业资格号：F03156295 彭梓烨0755-23887993pengziye@htfc.com从业资格号：F03152742 投资咨询业务资格：证监许可【2011】1289 号 目录 摘要.......................................................................................................................................................................................................1核心观点...............................................................................................................................................................................................1股指期货轮动与套利(一)：框架构建与因子检验............................................................................................................................ 4■四大因子维度...............................................................................................................................................................................................4■单因子择时信号构建...................................................................................................................................................................................8■总结.............................................................................................................................................................................................................14■风险提示.....................................................................................................................................................................................................14 图表 图1:风格择时因子框架| 单位：无............................................................................................................................................... 5图2:长短期SHIBOR走势| 单位：%......................................................................................................................................... 5图3:指数净资产收益率| 单位：%.............................................................................................................................................. 6图4:指数归母净利润| 单位：亿元............................................................................................................................................. 6图5:融资资金变动情况| 单位：亿元......................................................................................................................................... 7图6:ETF份额变化情况| 单位：亿份......................................................................................................................................... 7图7:IF、IC滚动收益| 单位：%................................................................................................................................................. 7图8:IF、IC主力合约年化基差率之差| 单位：%..................................................................................................................... 7图9:IC/IF与SHIBOR1W信号示意| 单位：无.........................................................................................................................8图10:SHIBOR信号轮动效果对比| 单位：无........................................................................................................................... 8图11:IC/IF与ROE信号示意| 单位：无....................................................................................................................................9图12:ROE信号轮动效果对比| 单位：无.................................................................................................................................. 9图13:IC/IF与ETF份额信号示意| 单位：无.......................................................................................................................... 10图14:ETF份额信号轮动效果对比| 单位：无.........................................................................................................................10图15:IC/IF与短周期动量信号示意| 单位：无........................................................................................................................11图16:短周期动量信号轮动效果对比| 单位：无......................................................................................................................11图17:IC/IF与长周期波动率信号示意| 单位：无................................................................................................................... 12图18:长周期波动率信号轮动效果对比| 单位：无................................................................................................................. 12图19:IC/IF与基差信号示意| 单位：无..................................
