S&P 500 Composition Distorts Valuation

"The problem with generic, 70-year historical win rates is that they treat the index as a single, uniform entity. They completely ignore a major, unique issue of our times when it comes to investing in the S&P 500. How the index is constructed today versus how it looked decades ago."

"There's a solid argument that the 'E' (earnings) in those ratios is an unsustainable bubble in itself."

"The U.S. stock market's valuation has reached levels historically associated with major downturns, as measured by the Buffett Indicator... stood at 218 per cent for the first quarter, just shy of the record high of 219 per cent touched in the prior quarter. The S&P 500 price-to-sales ratio currently sits at 3.22... That is well above its long-term historical average of 1.84, signaling stretched market valuations."

"The S&P 500 index today trades at a historically expensive valuation, calling into question the benchmark's return potential."

""What can do well in this monstrously expensive S&P 500 Index in a decade of heartache? Look no further than the 1970s," Smead wrote to clients on Thursday, pointing to how commodities vastly outperformed other asset classes in that decade."

"Stretched valuations, growth-inflation dynamics, and global uncertainties are signalling a correction ahead for the S&P 500?"

"The benchmark is trading at about 21 times expected earnings, down from over 23 in November, but still above its average forward price-earnings ratio of 19 over the past five years."

"The S&P 500's performance during this session reflects the ongoing market dynamics that continue to influence equity valuations."

"Rolling 10-year return correlations are misleading, as overlapping data and non-independent samples undermine their predictive validity for the SP500."

"Other data however, painted a mixed picture of the economy."
