2026:钟摆两端
Sou Hu Cai Jing· 2025-12-31 07:11
马克斯认为,"钟摆永不会停在中点",市场从来不是理性的直线,而是像永不停止的钟摆,始终在两个极端间来回摆动。 这种比喻,诠释了资产价格在情绪与价值博弈下所天然具有的巨大波动性。 行至尾声的2025年,正是人们领略市场波动势能的一年。 从年初的恒生科技龙头的估值修复,到4月份的对等关税黑天鹅,再到下半年科技股引领的科创两板攻势,市场呈现了一副曲折向上的过程。 这同样是权益资产守得云开见月明的积累,一年多前的"9·24"反转,让市场开始看见乐观;今年的A股结构式复苏,似乎守望中的黎明正在加速到来。 可是市场始终如钟摆一般,从来没有所谓的"均衡稳态",更多时只能从一个极端的非均衡,折跃到了另一个极端的远非均衡。 作者:资管风铃 1991 年,后来创办了橡树资本的霍华德・马克斯正置身于一场市场的剧震中。 刚刚经历美国储贷危机与海湾战争引发的恐慌性抛售,高收益债等资产被疯狂踩踏至低估区间,转年一季度市场又毫无征兆地迎来情绪反弹。 亲历过"漂亮 50" 等泡沫崩塌,见证了资产价格与投资情绪在贪婪与恐惧间的反复摇摆后,马克斯在当年4月的投资者备忘录中提出了一个形象的总结:钟 摆理论。 即将展开的2026年,市场参与者或许要 ...
