In a riveting discussion, Rob Arnott, founder and chairman of Research Affiliates, shares insights on the Fundamental Index and its impressive two-decade performance. He breaks down the complexities of the equity risk premium and explains why long-term forecasts hold more value than short-term ones. Rob also discusses the current value cycle and highlights intriguing trends, such as how companies removed from the S&P 500 often outperform those added, showcasing the nuances of market dynamics.
The Fundamental Index, which emphasizes company fundamentals over market capitalization, has historically outperformed the S&P 500 by about 2% annually for two decades.
Rob Arnott identifies that the equity risk premium is currently modestly negative, challenging commonly inflated investor expectations around stock performance versus bonds and cash.
Arnott suggests we may soon see a reversal in the value cycle, with value stocks potentially outperforming growth stocks due to their current undervaluation.
Deep dives
Fundamental Index Strategy
The Fundamental Index, developed by Rob Arnott, prioritizes weighting companies based on their business fundamentals rather than market capitalization. This method arose from concerns about the inefficiencies in traditional indexing, where overvalued stocks could dominate portfolios due to their market price. Historical data show that the Fundamental Index has outperformed the S&P 500 by approximately 2% annually over two decades. By focusing on fundamentals, this strategy also introduces a value tilt, emphasizing undervalued stocks while de-emphasizing growth stocks that may be overhyped.
Understanding Equity Risk Premium
The equity risk premium is the expected return for stocks over bonds or cash, which can be calculated through the differences in their yields and projected growth rates. Current analysis reveals that the risk premium is modestly negative, reflecting the current valuation multiples and yields available in the market. The misunderstanding commonly occurs when investors conflate historical excess returns with the actual risk premium, leading to inflated expectations for stock performance. A focus on the long-term yield, growth assumptions, and potential mean reversion is essential for a realistic outlook on equity returns.
Value Cycle Insights
Rob Arnott suggests that we may be nearing the bottom of the value cycle, with the potential for value stocks to outperform growth stocks in the coming years. Historical comparisons indicate that current valuations mark value as being significantly cheaper than growth counterparts, setting the stage for possible mean reversion. If value stocks revert to historical norms, they could outperform growth stocks by several percentage points annually over the next decade. Predictions suggest that while immediate market fluctuations are uncertain, a long-term view tilts the favor towards value investments.
Outperformance of Dropped Stocks
Research indicates that stocks removed from major indices, such as the S&P 500, tend to outperform their replacement stocks significantly over subsequent years. This trend is attributed to the fact that the dropped companies are often undervalued and unloved in the market, presenting a buying opportunity for savvy investors. Arnott’s study shows that stocks exiting indices outperformed by an average of 28% over five years, emphasizing the potential upside of investing in these overlooked entities. The newly created Next Index aims to systematically invest in these companies, capitalizing on their potential recovery and growth.
Active vs. Passive Indexing
While many perceive index investing as entirely passive, significant active decision-making occurs when companies are added or removed from the indices. For example, the S&P 500's index committee makes subjective decisions about inclusions, as seen with events surrounding Tesla’s unexpected inclusion. This selection process can lead to investors overpaying for stocks that are included in the index and suffering losses on stocks that drop out. Understanding these dynamics can help investors navigate the inherent vulnerabilities in indexing strategies and potentially enhance their returns by employing alternative approaches.
