How is the Alpha Score calculated?

Each dimension is built from several underlying metrics that are percentile-ranked against peer geographies, with some metrics inverted (for example, high months-of-supply lowers Inventory Health).

The five dimension scores are then combined using the fixed weights above. A market with no real data for a dimension has that slice left out rather than filled in, and the other weights are re-scaled so the score averages only what we actually measured. Below three measured dimensions we show no score instead — a number built mostly from filler looks like a measurement and is not one. See the methodology page for every metric and weight.
