Core Insights - The recent trend among public funds shows a significant reduction in stock concentration, indicating a shift in investment strategy due to increased market complexity and external uncertainties [1][2][4]. Group 1: Fund Behavior - Many funds, such as Penghua Carbon Neutral Theme A, have reduced their heavy stock holdings from 63% at the end of last year to 44% by the end of the first quarter [1]. - The reduction in stock concentration suggests that fund managers are finding it challenging to identify clear investment themes, especially after substantial gains in sectors like technology and robotics [2][4]. Group 2: Market Conditions - The market has become more difficult to navigate, with fewer emerging themes compared to the previous quarter, leading to a cautious approach from fund managers [2][4]. - Increased external uncertainties have made high stock concentration riskier, prompting funds to diversify their holdings to mitigate potential negative impacts on net asset values [2][4].

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 ...

对于不少投资者而言，量化投资像是个带着神秘色彩的"黑匣子"。近年来，随着量化投资的蓬勃发展及人 工智能的加持，越来越多的投资者开始主动关注、理解这类投资策略。 但对于不同的基金经理，量化工具发挥的作用并不相同。本期，我们邀请中泰证券资管量化公募部总经理 李玉刚做客直播间，就以下问题进行解答。 李玉刚 我们可以把投资当作认知跟决策的一个分支，大家经常说投资是认知的变现。说到对投资的评 价，首先要知道投资是一个属于不确定性的领域的游戏， 在这样的游戏中，我们更应该关注过程，而不 是注重结果 。 主播 为什么？作为投资者，肯定是关注收益的。 李玉刚 对，但短期的收益是受很多因素影响。短期好的结果，不代表整个过程是好的。从长期来说，我 们知道长期投资收益来源于较高质量的决策过程，这是一个前提。 主播 也就是说长期的收益不是短期收益积累来的。 李玉刚 它不是简单加权的过程。比如一只股票可能长期表现不好，或处于下跌状态，但投资这只股票的 收益，在这种不确定性领域的收益，不是时间的加权（通过时间简单累积收益），这点是比较明显的。 讨论这个问题，大家应该接受一个前提，就是在投资上，尤其是注重长期收益的投资者，我们更应该关注 ...
