What the spread means
The -15.3% median spread between the 30 and 35 is the secondary market's read on the marginal cost of going one size up. Boutique retail typically prices the step at 10–20%; if the secondary spread is tighter, the market is discounting the size step relative to retail.
Which is the more liquid configuration
On 90-day sample size the 30 is the more liquid configuration (185 observations vs 147 for the 35). Liquidity bears on bid-ask: deeper sample means tighter spreads around the median and shorter time-to-clear for a typical listing.
Verdict
On premium-to-retail the 35 is the more efficient entry — a smaller markup over boutique retail at +62.3% vs the alternative.

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. All numbers reflect the latest 90-day aggregation for each variant individually. CAGR uses anchor-aligned aggregations with a ±180-day window; missing anchors mean a blank cell rather than a stale comparison. Premium-to-retail uses the latest US boutique price.
