摘要

摘要周期性调整市盈率（CAPE）是一种被广泛用于预测市场回报的工具。然而，最近，其预测强度的恶化已经浮出水面。与此同时，全球长期利率已经下降，预计将保持在历史低点，而CAPE没有考虑到这一点。忽略了对资本成本对CAPE作为估值工具的有效性的影响，这代表了知识上的差距。这项研究使用了一个修正的CAPE来解释利率，称为超额CAPE收益率（ECY），为预测全球股市回报提供了一个替代的——并且可能得到改进的——模型。我们发现，当实际利率在3%至5%之间时，CAPE达到峰值，而ECY未能提高CAPE的预测能力。

A modified Shiller's cyclically adjusted price-to-earnings (CAPE) ratio for stock market index valuation in a zero-interest rate environment

ABSTRACT The cyclically adjusted price-earnings ratio (CAPE) is a tool that has become widely used to predict market returns. However, recently, deterioration in its forecast strength has surfaced. At the same time, global long-term interest rates have declined and are expected to remain at record lows, which the CAPE fails to consider. Omitting to fully examine the impact of the cost on capital on the effectiveness of CAPE as a valuation tool represents a gap in knowledge. This study uses a modified CAPE to account for interest rates, known as the excess CAPE yield (ECY), to offer an alternative – and potentially improved – model for predicting global stock market returns. We find that CAPEs peak when real interest rates are between 3% and 5%, while the ECY fails to improve on the predictive abilities of the CAPE.
