Analysis of Value Investing Failures

This article is a technical report summarizing the findings of a study titled 'When Valuation Fails,' published in The Journal of Portfolio Management. The report discusses the decline of the value investing style, which has historically provided a return premium but has underperformed over the last two decades, particularly since the 2008–2009 financial crisis. The authors attribute this underperformance to technological changes and the accounting treatment of intangible assets. The study evaluates the implications of the failure of relative valuation signals used in tactical asset allocation models, examining various hypothetical portfolio scenarios. It highlights the challenges faced by investors in identifying turning points in relative valuation performance and the emergence of value traps. The report also introduces a new methodology for evaluating back-tested performance, emphasizing the need for sophisticated approaches that incorporate momentum and accounting adjustments. The conclusions suggest that while relative valuation models have struggled, tactical allocation based on relative value remains viable with a more nuanced understanding of market dynamics.
