一个用于组合估值估计的贝叶斯框架

A Bayesian Framework for Combining Valuation Estimates

Kenton K. Yee

摘要:

获得更准确的股票价值估计是股票选择的起点,在嘈杂的市场中基于价值的指数,并通过战术风格轮换击败基准指数。不幸的是,贴现现金流、可比方法和基本面分析通常会产生不一致的估值估计。此外,估值估计通常与市场价格不一致。一个人能否通过对包括市场价格在内的各个估计进行平均来形成一个优越的估值估计?本文提出了一个贝叶斯框架,用于将两个或多个估计组合成一个更优的估值估计。该框架证明了对几个估计数求平均值以得出最后点估计数的常见做法是合理的。

英文摘要:

Obtaining more accurate equity value estimates is the starting point for stock selection, value-based indexing in a noisy market, and beating benchmark indices through tactical style rotation. Unfortunately, discounted cash flow, method of comparables, and fundamental analysis typically yield discrepant valuation estimates. Moreover, the valuation estimates typically disagree with market price. Can one form a superior valuation estimate by averaging over the individual estimates, including market price? This article suggests a Bayesian framework for combining two or more estimates into a superior valuation estimate. The framework justifies the common practice of averaging over several estimates to arrive at a final point estimate.
