Cohort analysis — July 14, 2026: Louis Vuitton Speedy by production year

Cohort analysis groups secondary-market listings by the bag's year of production rather than by transaction date. The cut answers a different question than the standard variant median: not what is a Louis Vuitton Speedy worth today, but how does the value of a Speedy produced in a specific year compare against one produced in another year.

Why we are showing the framework, not the table

For the Louis Vuitton Speedy, our listing sample does not currently carry year-of-production tags on enough rows to support a per-cohort median calculation. Year-of-production tagging depends on sellers surfacing the bag's blind stamp (Louis Vuitton Hermès) or serial-number range (Chanel/LV); listings that don't surface this metadata simply don't enter the cohort cut. As coverage deepens we will publish a data-driven cohort breakdown for this model.

The cohort framework in general

Cohort effects in luxury handbags work through three channels. The first is hardware revision: brands occasionally refine the metalwork on a model — a clasp redesign, a logo etch, a new metallurgy — and bags produced before the revision are visually distinct from bags produced after, with the secondary market typically rewarding whichever configuration the current cultural moment prefers. The second is leather-supplier evolution: the same nominal leather shifts subtly as tanneries are switched or formulations change; collectors notice and price the cohorts differently. The third is condition expectations: a ten-year-old bag in excellent condition has been excellently maintained over ten years; a two-year-old bag in excellent condition has been carefully used for two. The implicit durability signal is different. Across our coverage the most common cohort pattern is a mild age discount: each year of production added between manufacture date and today shaves a few percent off the median secondary price. The less-common but more interesting pattern is the vintage-premium window, where bags from a specific cohort range carry a premium over both newer and older bags — typically because the cohort window coincides with a particularly desirable hardware spec or leather formulation.

Methodology

Part of the Bagonomics daily editorial rotation — a 14-day cycle of daily research pieces. Each day's slot is selected from the rotation by day-of-year so the same calendar date always lands on the same topic. Data is frozen at publication; live numbers are visible on the linked entity pages. Cohort cuts use listing-level year_produced where the seller surfaces it. Medians here are computed off asking price for transparency at the cohort level — the headline variant medians on Bagonomics use sold-price data where available.
