Wine Sell-Through & Liquidity Index (WSLI)
Wine Sell-Through & Liquidity Index (WSLI): a daily index measuring the tradability of the fine wine market, sell-through rate and hammer-to-estimate performance, built on ALT/FNDATA's dataset of over 940,000 sold and 120,000 unsold lots across 290+ auction houses since 1998. It tracks market liquidity and demand, not just price. Daily index values.
What this listing delivers
- Daily liquidity index for fine wine: sell-through rate and hammer-to-estimate performance, built on 940,000+ sold and 120,000+ unsold lots across 290+ auction houses since 1998.
- Measures tradability and demand, not just price, an input academic research flags as central to wine as an illiquid asset and one price-only indices miss.
- 890,000+ lots carry both a hammer price and pre-sale estimates, so sell-through and estimate accuracy compute by region, producer and vintage. Delivered in JSON, CSV and SQL formats.
Coverage & methodology
The Wine Sell-Through & Liquidity Index (WSLI) measures how liquid the fine wine market is, the sell-through rate and how hammer prices land against estimates, rather than price level alone. Liquidity is a factor academic wine economists identify as central to wine as an illiquid alternative asset, and one that price-only indices ignore.
