S&P 500 Valuations Trigger Major Red Flag as Corporate Profits Soar

The S&P 500 has experienced an impressive run, doubling since the start of 2023 and producing a 15% annualized return since its March 2009 low.

This surge has led some investors to wonder if we're approaching a new market peak, similar to the 'lost decade' seen in the late 1990s and early 2000s.

The S&P 500's current valuation is a major red flag, with its price-to-earnings (P/E) ratio based on expected earnings for the next 12 months sitting at around 20, well above the average of about 16 over the past 40 years.

The cyclically adjusted price-to-earnings ratio (CAPE), which looks back at the last decade of earnings and adjusts them for inflation, currently exceeds 42, a level unseen since August 2000 and never before the 1999-2000 dot-com bubble.

However, there's an important difference between today's market and that of the late 1990s: the strength of corporate profits. After-tax corporate profits reached 13.24% of GDP in the second quarter, the highest on record dating back to 1947.
