Ford Mustang (S550) GT350
Flagged undervalued because sell-through 99%.
What It's Actually Worth
Blended value of a standard 7 yr, 5k mi example, ~$67.6K 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.
Did our model work? 74% direction calls right
Each faint amber line is a forecast we would have made at that point in the past (12-mo horizon), drawn against what actually happened (blue). Over 39 scored forecasts: 74% got the direction right, median value error ±11%.
Walk-forward: each ghost uses only data available at that date — no hindsight. Data-backed market intelligence, not a guaranteed prediction. Figures are modeled estimates from asking prices, sold comps, and public economic indicators; they can be wrong. Not financial advice.
Auction Scorecard gavel in range 9 in 10
We replayed 110 past auctions in this market — predicting each hammer price from market data before the sale (no hindsight). Typical miss: ±17%; the gavel landed inside our predicted range 9 in 10 of the time, and we lean slightly low on average.

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 (moderate conviction — 50% of weighted drivers agree), driven mainly by 2-Year Treasury Yield and Nasdaq Composite, though Consumer Discretionary ETF (XLY) points the other way.
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
