What Happened After The Last Time The S&P 500's Forward P/E Was This High

Despite the S&P 500's forward P/E multiple of 22.9x being significantly above its 10-year average, the article contends that valuation ratios alone are unreliable short-term market predictors. It highlights that similar elevated P/E levels in 2020 preceded a near doubling of the index, driven by commensurate earnings growth. With double-digit earnings growth projected through at least 2027, P/E multiples could compress through rising earnings even if prices continue to climb, emphasizing that market corrections are not guaranteed and are difficult to profitably trade.

Analysis

The S&P 500's forward P/E multiple currently stands at 22.9x, notably above its 10-year average of 18.6x, as reported by FactSet. However, valuation ratios alone are not reliable short-term market predictors. A similar elevated P/E of 23.6x in August 2020 preceded a near doubling of the S&P 500 from approximately 3,500 to 6,900 over five years.

This significant market appreciation, despite relatively stable P/E ratios, was primarily driven by a commensurate doubling of corporate earnings, supported by persistently high profit margins. While the period included a bear market in 2022 and a 19% rout earlier this year, the long-term trend highlights earnings as the critical driver.

Earnings are projected to grow at a double-digit rate through at least 2027, which could lead to P/E multiple compression even if stock prices continue to climb. As BofA's Savita Subramanian noted, P/E multiples can decrease from rising earnings, not just falling prices. This suggests that current elevated valuations do not necessarily guarantee an imminent market correction.

The article emphasizes that market sell-offs are not guaranteed and are historically challenging to trade profitably. The focus on long-term earnings growth as the primary market driver suggests that investors should prioritize fundamental strength over short-term valuation concerns.

Key Decisions for Investors

• Investors should temper reliance on elevated P/E ratios as a sole short-term market timing indicator, given their historical unreliability.
• Prioritize companies and sectors demonstrating strong, sustainable earnings growth, as this is identified as the most critical long-term driver of stock prices, projected to grow double-digit through 2027.
• Maintain a long-term investment perspective, recognizing that market corrections are not guaranteed and attempting to time market fluctuations based solely on valuation has historically proven challenging.
