霍华德·马克斯:风险·第12则

霍华德·马克斯《《风险》》· Risk · 投资 · 决策

First of all, given the inextricable linkage between analyzing a potential investment and assessing its risks, I question whether anyone else can know as much about this subject as the investment professionals directly involved. To me, “risk measurement officers” sound like armchair quarterbacks who’re brought in to tell the investment pros how they’re doing (although I concede that they may be useful in looking across the “silos” in multi-strategy portfolios to aggregate risk and look for fault lines). Second, I sincerely doubt that the risks that really matter are subject to modeling.

白话

首先,分析潜在投资和评估其风险密不可分,所以我怀疑外部人能否比直接参与的投资专业人士更懂风险。在我看来,“风险测量官”就像事后诸葛亮,被请来告诉投资专家他们做得如何(尽管我承认,他们在跨越多策略组合的“筒仓”来汇总风险和寻找断层线方面可能有用)。其次,我真心怀疑真正重要的风险是否适合建模。因为风险往往难以量化,依赖模型可能给人虚假的精确感。

今日一问

你依赖的风险模型是否忽略了真正重要的不确定性?
