What It's Actually Worth
Blended value of a standard 2 yr, 2k mi example, ~$74.5K now. The green line weighs confirmed auction sales most heavily (the amber dots — what cars actually hammered for), blends in fast-selling "just-missed" listings, and lightly smooths out month-to-month composition noise.

Lead Indicator Forecast
Some indicators move before this market does. 10Y-2Y Yield Spread has historically led it by about 15 months — so its recent move implies where prices head next (dashed). The solid green line is actual value through today; the shaded path is what the lead implies.
BECAUSE 10Y-2Y Yield Spread fell 12%. THEREFORE, given its usual 15-month head start, we lean DOWN — about −2% (≈ −$1,667) over the next 15 months. Confidence: High (correlation +0.76, 40 months overlap).
Crystal Ball — What Leading Indicators Signal
Distinct from the trend forecast above: this blends all 8 leading indicators (each at its own lead time, de-duplicated so correlated ones don't double-count) into one signal. Leading indicators are collectively signaling higher over the next ~12 months (high conviction — 73% of weighted drivers agree), driven mainly by 10Y-2Y Yield Spread and US Regular Gas Price, though US Regular Gas Price points the other way.
⚠ The price trend and leading indicators disagree — momentum may be running ahead of the fundamentals.
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
