I do, too. 10-12 years as well. Many indicators are saying that: forward returns vs P/E, P/S, CAPE, market cap/GDP, non-farm market cap/gross value added (Hussman), non-farm equity/debt (St. Louis Fed (FRED): ((Nonfinancial Corporate Business; Corporate Equities; Liability, Level+Domestic Financial Sectors; Corporate Equities; Liability, Level)/1000)/(((Nonfinancial), GMO's proprietary model, etc. All of these are forecasting zero to negative stock market returns.

True, but having tracked many of those metrics myself for quite some time, I can attest that these indicators have been predicting this for many years while the market continues to rise. How much longer could that continue? Another 5 years? Another 10? More?

I've never been one to believe "this time it's different", yet the more I ponder on what a potential future could look like if a US-led AI boom truly does spark a new industrial revolution marked by enormous increases in productivity and business earnings as some predict, the more I find myself having doubts about the merits of sitting on even a modest cash pile or hedges, and more and more concerns about potentially missing out.

I find myself questioning: what if currently elevated valuation ratios across the market are accurately reflecting a coming wave of earnings surges driven by AI in the next few years?
