● 经济前瞻指标：维持下行判断。 根据本月更新的经济前瞻指标模型提示，2026年2月处于2025年12月以来下降周期的初期，预计未来将持续下行。 ● 低波因子表现回归、形成共振。 按照定量指标的结果，目前经济出现转弱、流动性略偏松，信用指标略好，微观映射中经济（盈利预期）中等，流动性也为正，信用则继续 修正为偏弱，因此宏观各维度的方向继续为 经济偏弱、流动性偏松和信用收缩 ，与上期一致。本期我们主要按照对经济不敏感、对流动性敏感、对信用不敏感来选择得分前三 的因子，目前成长价值都无明显偏好，由于沪深300中低波动率因子回归，当前其成为宏观、动量选中的共振因子；中证500中去除反转因子，增配小市值，低波同样形成共 振；中证1000维持成长、低波的共振。 ● 大类资产配置观点：小幅配置美股。 结合当前指标，修正后目前经济偏弱、流动性偏松、信用收缩，债券的观点好转，但受其他资产影响仓位仍偏低，黄金虽然上周下跌但 目前基于动量维持配置。 ● 流动性：维持略偏松。 1月我国短端利率进一步有所回落，长端利率仍略高于均线，但利率信号保持宽松；货币量方面，货币投放量回升到0以上，但未突破1倍标准差，信 号维持中性，而超储率仍 ...

传统量价因子的集体失效与其 整体偏反转的逻辑相关， 为偏动量特征的行业轮动模型的因子化提供了场景。 2 026 年以来， 低波、反转、市值、低流动性因子反向，对策略 超额影响较大，其集体失效的原因与行情热度持续、逻辑偏反转的因子失效。 如果能有一个偏动量特征的因子进行一定的调和，或许 能增强组合超额的稳定性。 量化 行业轮动模型追求的超额稳健性， 为行业轮动模型的因子化提供了基础。 一直以来，量化的行业轮动模型缺乏较好的使用场景，量化 策略 追求超额的稳定性，使得行业 轮动模型所选出的行业往往不会 很 极致，而这个稳健特征如果只是对标所有行业的平均值，对于大部分投资者来说缺乏实际意义。但这种稳健性反而是选股因子的需求，这就 给行业轮动模型的选股因子化提供了基础。 经过我们测算， 行业轮动因子具备良好的因子特性：因子月度IC达5 .3% ，ICIR达4 .0 ，属于表现较强的因子，因子的累计IC、多空表现都有不错的特征。尤其是 该因子近年 来快速上行，体现出牛市的强进攻特征和动量属性 。 行业轮动因子加入传统的多因子框架可以有效提升模型在近年来的表现。 在传统多因子框架中加入行业轮动因子，不仅大幅提升了超额收益 ...

1. 期权的杠杆的来源 期权被誉为金融市场的 " 衍生品之王 " ，其最具吸引力也最具风险的特征之一便是 杠杆效应 。许多投资者被期权 " 以小额资金撬动大额收益 " 的潜力所吸引，却往往对其 杠杆原理与动态机制一知半解。深刻理解杠杆的本质与变化规律，是驾驭这一金融工具、避免被其反噬的关键。 与融资融券、期货等其他杠杆工具不同，期权的杠杆 内生于产品设计 。期权本质是一种 " 选择权 " ，买方通过支付 权利金 获得在未来约定时间以约定价格买入或卖出标 的资产的权利。该权利所对应的资产规模（如 100 股股票、一份指数合约等）的总市值，即为 标的资产价值 。期权的杠杆，正源于 标的资产价值 与 权利金 之间的悬殊比例 —— 以较小的资金代价，控制价值远高于自身的资产，从而形成收益与风险的放大效应。 这种"权利杠杆"与期货的"保证金杠杆"有本质区别。期货杠杆源于 投资者 为一份"未来必须履行"的买卖合同所缴纳的担保金，盈亏与标的资产波动直接挂钩，风险与收益对 称且可能无限。而期权（买方）杠杆则源于 投资者 为一份"未来可以选择是否履行"的权利所支付的"入场费"，其最大损失在买入时即已锁定，风险与收益是非对称的。 ...
