Retail and eCommerce data metrics, defined

Definitions of the retail and alternative-data metrics used in consumer investment research, including markdown breadth, discount depth, in-stock rate, matched-SKU inflation, mix shift, shrinkflation, online share of shelf and brand-to-ticker mapping, with how each is measured and its common pitfalls.

Alternative data (shelf-side)
Non-traditional data used in investment research; shelf-side data measures what is listed, at what price and availability, rather than what was bought.
Assortment count
The number of distinct products a brand or retailer has live for sale at a point in time.
Assortment rationalization
A deliberate reduction in the number of products a brand or retailer offers, often called SKU rationalization.
Brand-to-ticker mapping
Linking each consumer brand to the company that owns it and to that company's listed security, with ownership changes dated.
Channel leakage
Products moving from premium retailers to off-price retailers, a signal of excess inventory and brand-positioning risk.
Discount depth
The average percentage reduction from full price across products that are on sale.
DTC vs wholesale mix
How a brand's online assortment and pricing split between its own direct-to-consumer site and its wholesale retail partners.
Full-price availability
The share of a brand's products that are both in stock and selling at full price, a proxy for clean, healthy demand.
In-stock rate
The percentage of a brand's or retailer's listed products that are available to buy.
Markdown breadth
The share of a brand's or retailer's live products that are selling below their full price at a point in time.
Matched-SKU inflation
The price change of identical products observed in both periods, which isolates true price moves from changes in product mix.
Mix shift
The part of an average-price change explained by a change in which products are on sale, rather than by price changes on the same products.
New-product share
The percentage of a brand's live assortment that was first seen within a recent window, such as the last 13 weeks.
Price architecture
How a brand's or category's products are distributed across price tiers, such as value, mid-market, premium and luxury.
Price gap
The percentage difference between the price of one product or brand and a comparable alternative, such as branded versus private label.
Price pass-through
The share of a cost increase, such as a tariff or input-cost rise, that a company passes on to customers through higher prices.
Private label share
The share of a retailer's assortment in a category made up of its own-brand (private label) products.
Promotional intensity
How heavily a brand, retailer or category relies on discounts, combining how often products are promoted and how deep the discounts are.
Share of shelf (online)
A brand's share of the products a retailer lists in a category, measured on the retailer's website.
Shrinkflation
A price increase delivered by reducing pack size while keeping the shelf price the same or similar.
