Is the stock market in a bubble right now?

I wanted one page I could glance at to see how stretched the stock market is right now — so I built a live dashboard. It pulls public data (FRED + multpl) and updates itself, no manual work. Green = healthy, amber = caution, red = overvalued or flashing a warning.

What each one means

Valuation — how expensive are stocks vs fundamentals?

• Shiller CAPE ratio — price ÷ 10-year average inflation-adjusted earnings. The best long-run return predictor we have: a high CAPE has historically meant weak returns over the following decade. Long-term average is ~17.
• Buffett Indicator — total US stock market value ÷ GDP. Buffett called it "probably the best single measure of where valuations stand"; above ~150–200% is "playing with fire."
• Tobin's Q — market value of companies ÷ what it would cost to rebuild them (replacement cost). Long-run mean is ~0.75; above 1 means the market prices companies above their tangible worth.

Sentiment & positioning — is everyone already all-in? (contrarian signals)

• BofA Bull & Bear Indicator and equity allocation surveys — extremes are contrarian. When everyone's maximally bullish and fully invested, there's no one left to buy.
• M&A volumes — record deal-making means executives are buying at peaks, historically near tops.

Technical & macro breadth — is the plumbing healthy?

• Hindenburg Omen / Titanic Syndrome — internal market weakness (lots of new highs and new lows at once = an unhealthy, divided market).
• Yield curve — an inverted 10y–2y curve is the most reliable recession lead indicator. Notably, recessions usually hit after it un-inverts, not during the inversion itself.
• S&P 500 ÷ M2 — valuation adjusted for the money supply, so "record highs" that are really just monetary inflation don't fool you.

No single one calls a top — but when several cluster in the red at once, that's the robust warning.

Not investment advice — just data I find useful.
