**风格因子表现**：BETA、成长和中盘风格因子表现较好，分别上涨0.62%、0.54%和0.30%；残差波动率、价值和杠杆风格因子表现较差，分别下跌-0.14%、-0.31%和-0.38%。 - **市场情绪**：市场情绪高涨，但指数处于高位，需警惕回调风险。建议保持哑铃型配置，增配高换手及TO策略，同时维持一定小盘指增仓位，以把握可能延续的科技行情。对于大盘和红利指增策略，可适当上调仓位占比，以增强防御能力。 - **中性策略**：中性策略收益稳定，建议平配，作为指增策略的补充，以对冲回撤风险。 - **行业表现**：本周有16.1%的行业获得正收益，通信板块表现最佳，周收益率达6.77%；表现最差的行业为美容护理（-5.63%）、钢铁（-5.92%）和有色金属（-7.39%）。 ## 关键信息 ### 1. 主要宽基指数回顾 - **短期活跃度**：市场活跃度处于中高位置，节后成交量上升。 - **波动率**：本周宽基指数波动率多数下降，其中中证500波动率为21.69%（66.40%分位），中证1000波动率为19.45%（47.35%分位），中证2000波动率为19.08%（33.47%分位），中证全指波动率为16.34%（53.70%分位），沪深300波动率为13.42%（43.92%分位）。 ### 2. 期货市场回顾 - **基差走势**：IF、IC、IM基差走阔，各合约对冲预估影响中性产品平均收益分别为0.180%、0.380%、0.240%。 - **今年基差表现**：300中性收益为-0.580%，500中性收益为-1.360%，1000中性收益为-2.460%。 ### 3. 期权市场回顾 - **隐波变化**：本周隐波普遍上涨，有利于已持有的买权策略。 ### 4. 策略环境监控 - **日内Alpha环境**：本周股票市场日均净流出1020亿元，资金净流出不利于日内Alpha积累。 - **交易型Alpha环境**：大盘风格为主，不利于交易型Alpha积累。中证1000、中证500、沪深300中能打败基准指数的股票数量处于中等偏差水平。 - **持有型Alpha环境**：沪深300指增超额环境处于中等水平，中证500和中证1000指增超额环境处于中等偏差水平，整体对Alpha积累影响不利。 - **股指对冲环境**：基差波动率下降，成本管控压力下降，IF、IM、IC基差走阔。 ### 5. 未来策略研判 - **多头策略**：建议增配高换手及TO策略，保持哑铃型配置，维持一定小盘指增仓位，同时保证大部分大盘红利指增仓位作为防御。可考虑配置带有看跌期权保护的指增产品，以预防回调风险。 - **中性策略**：建议平配，作为指增策略的补充，对冲回撤风险。 ## 风险提示 - 中东冲突升级 - 因子失效 - 模型失效 - 市场主流策略偏移 ## 附录：主要指数月度表现对比 | 指数类别 | 主要指数 | 今年收益率 | 2026年4月 | 2026年3月 | 2026年2月 | 2026年1月 | 2025年12月 | 2025年11月 | 2025年10月 | 2025年9月 | 2025年8月 | 2025年7月 | 2025年6月 | 2025年5月 | 2025年4月 | |----------|----------------|------------|----------|----------|----------|----------|-----------|-----------|-----------|----------|----------|----------|----------|----------|----------|----------| | 大盘 | 上证指数 | 4.20% | 0.56% | 4.14% | -6.51% | 1.09% | 3.76% | 1.40% | -1.67% | 1.85% | 0.19% | 8.37% | 3.34% | 2.90% | 2.09% | | 大盘 | 沪深300 | 4.96% | 1.09% | 6.21% | -5.53% | 0.09% | 1.65% | 1.17% | -2.46% | 0.00% | 2.59% | 10.90% | 3.37% | 2.50% | 1.85% | | 大盘 | 中证A500 | 8.21% | 1.42% | 7.00% | -7.35% | 1.14% | 4.52% | 2.50% | -2.56% | -0.62% | 3.69% | 12.11% | 3.81% | 2.82% | 1.53% | | 中盘 | 中证500 | 14.34% | 2.24% | 7.73% | -12.02% | 3.44% | 12.12% | 5.12% | -4.08% | -1.10% | 4.25% | 13.37% | 4.91% | 4.31% | 0.70% | | 中盘 | 中证1000 | 14.32% | 3.59% | 7.96% | -10.99% | 3.71% | 8.68% | 2.82% | -2.30% | -0.90% | 0.98% | 11.52% | 4.51% | 5.47% | 1.28% | | 微大盘 | 中证2000 | 14.38% | 4.31% | 6.15% | -10.70% | 4.80% | 8.16% | 2.90% | -0.40% | 0.34% | -1.32% | 9.17% | 4.21% | 6.40% | 4.11% | | 微盘股 | 微盘股指数 | 17.69% | 0.07% | 6.82% | -7.77% | 6.59% | 10.71% | -2.18% | 4.40% | 5.83% | 1.35% | 3.18% | 8.12% | 10.23% | 10.21% | | 红利风格 | 中证红利 | 3.20% | -3.15% | 2.33% | -1.70% | 2.22% | 3.56% | -1.57% | -1.45% | 3.05% | -1.15% | 0.97% | 0.56% | -0.65% | 1.95% | | 科技风格 | TMT指数 | 17.07% | 5.92% | 8.82% | -12.95% | 3.71% | 10.17% | 1.23% | -1.42% | -0.62% | -0.57% | 13.14% | 4.97% | 10.33% | 2.32% | | 科技风格 | 创业板指数 | 22.66% | 6.85% | 13.23% | -3.79% | -1.08% | 4.47% | 3.58% | -4.23% | -1.56% | 9.53% | 24.43% | 8.40% | 8.02% | 2.32% | | 科技风格 | 科创50指数 | 26.19% | 7.97% | 21.02% | -15.57% | -1.42% | 12.29% | 0.56% | -6.24% | -5.33% | 10.18% | 29.37% | 5.34% | 2.70% | -3.50% | | A股整体风格 | 中证全指 | 9.50% | 2.19% | 6.65% | -8.69% | 2.23% | 5.75% | 2.28% | -2.28% | -0.15% | 1.84% | 10.91% | 4.07% | 3.98% | 2.10% | | 均衡风格 | -
