Dave Collum: S&P 500 price-to-sales ratio above long-term norms, SpaceX surpasses 100 — S&P 500 and SpaceX valuation ratios

Dave Collum, professor / financial commentator at Cornell University (Emeritus), draws attention to current price-to-sales ratios for the S&P 500, noting that long-term norms—excluding the late 1990s/2000s bubble—are often below 1.0, or about 0.83.

Collum adds that SpaceX's price-to-sales ratio is greater than 100, making it a clear outlier compared to historical benchmarks for public equities.

But we saved everything 🙂.

Collum has previously highlighted a surge in the margin debt-to-GDP ratio, noting an increase from its 1966-1990 average to 5.0. He has also discussed historical perspectives on investing, recommending multi-century research by Ed McQuarry on investment analysis. The comments place current market ratios in the context of longer-term financial trends.
