Too little corroboration in the last 3 days to call a trend (2 articles). Watching for it to gain traction.

WHAT PEOPLE ARE SAYING

The S&P 500's cyclically adjusted price-to-earnings ratio has risen above historical levels associated with major market peaks, including the Great Depression and dot-com bubble, suggesting the market faces structurally depressed returns over the coming decade. This metric implies limited upside from current valuations.

WHY IT MATTERS

Elevated valuation multiples constrain forward returns by reducing the margin of safety and limiting the multiple expansion that can drive gains, forcing investors to rely primarily on earnings growth to generate returns. When valuations reach extremes relative to historical norms, the market becomes more sensitive to disappointments in growth or earnings, increasing volatility and downside risk.

"The ratio rose above 30 before the Great Depression. It later reached an all-time high of about 44 just before the dot-com bubble burst. As of the report, the CAPE ratio is above 41. That puts the current market at levels that have historically been associated with very high valuations."
