Used-Car Price Landscape
» Kelley Blue Book and others provide current estimates of used-car
market value but they do not provide forecasts and scenarios.
» Many providers produce subjective assessments of future car values.
ALG combines model-driven projections with subjective overlay.
» Stress-testing has revealed a need for wholly model-driven
projections. Rigorous back-testing and complete documentation are
also mandatory.
» Many applications suggest that purely quantitative approaches
compete very favorably with subjective assessments. Models users’
own subjective overlay can be applied to a “clean canvas.”

Introducing: AutoCycle™
Moody’s Analytics AutoCycle™ solution offers a quantitative, consistent,
and documented methodology for incorporating economic factors into car
price forecasts.
» Forecasts are driven by macro factors (supply and demand drivers of
vehicle value in different categories).
» Account for mileage and age; some variations in trim levels.
» We can project both existing and future model years (i.e. 2016 Jeeps).
Phase 1 Complete Complete demo based on models developed for existing clients. These are portfolio-level models
geared to stress-testing lease portfolios of popular car brands.
Phase 2 Apr 2015 More general models developed to cover the full range of cars and trims at a highly granular level.
These models are also geared to portfolio-level analysis.
Phase 3 Jun 2015 VIN-level models, calibrated to the portfolio-level projections, that allow us to consistently capture
individual vehicle characteristics (such as extreme mileage or premium trim packages).

Data and Structure
We use data from Auction.net in the U.S. These are wholesale auction
price outcomes observed over many years.
Data cover a very wide range of brands. Popular brands are better
populated (and this produces more accurate results) than secondary or
exotic brands.
We have done similar work in Canada and can do this on a custom basis.
