超额（相对）收益与绝对收益真的是不可兼得的鱼和熊掌吗？长期主义者会给出不一样的答案——可持续 的超额（相对）收益本质上是绝对收益的时间积分形态。 物理学家费曼说："量子力学之所以难以理解，是因为我们总用经典世界的语言描述它。"资本市场同样如 此——当投资者用线性思维理解非线性的收益获得机制，必然陷入认知困境，如粒子位置与动量不可同时 精确测定一样。 在投资领域同样存在"风险、收益、可持续性"的不确定性三角 ： ★ 宣称高绝对收益者，往往承受隐性尾部风险（长期资本管理公司的陨落）； ★ 标榜可持续性者，常以牺牲收益锐度为代价（固定收益类产品的平庸回报)； ★ 追求超额收益者，难逃时间维度的均值回归（连续跑赢市场的主动管理基金数量了了）。 对投资者而言，就像一场在迷雾中前行的冒险，收益的测不准性让投资领域充满了悬念与变数，许多投资 者陷入"超额（相对）收益与绝对收益对立"的思维困境。 这并非文字游戏，而是数学规律的必然。当某组合每年以2%的幅度持续跑赢标普500指数，30年后的累计 超额收益将高达81.1%，相当于在美股百年长牛的贝塔地基上，用阿尔法的复利魔法建造出一座收益金字 塔。 历史反复验证：当管理人以长期 ...
