Jaguar XJS
Flagged undervalued because -12% vs 2-yr avg, -8% vs 3-yr trend, inventory -0%, and sell-through 86%.
What It's Actually Worth
Blended value of a standard 33 yr, 61k mi example, ~$12.6K 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? 59% 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 135 scored forecasts: 59% got the direction right, median value error ±40%.
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.

Crystal Ball — What Leading Indicators Signal
Distinct from the trend forecast above: this blends all 5 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 lower over the next ~12 months (low conviction — 14% of weighted drivers agree), driven mainly by Ethereum (USD) and High-Yield Bond Spread, though Ethereum (USD) 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.

What This Market Follows
