Luxury Inventory Signal Index
(LISI)
LISI measures the accumulation of physical inventory across local markets, functioning as an observational measure of changes in premium automotive inventory that may precede broader macroeconomic indicators.
Methodology & Focus
Empirical Measure
By tracking un-cleared inventory at the local level, LISI documents behavioral shifts that may precede changes in lagging administrative indicators like employment or GDP.
Granular Diffusion
LISI calculates breadth across 350+ metro-model cells, helping distinguish isolated local shocks from structural macroeconomic regime shifts.
Clean Alternative Data
Derived from publicly available inventory observations collected through an automated data pipeline, reducing reliance on survey-based estimates.
