S&P Global Luxury Index

The S&P Global Luxury Index carries an authority that boutique or advisory-firm indices can't fully replicate, simply because S&P Dow Jones Indices is the institutional standard for benchmark construction and its methodology, rebalancing rules, and investability screens are transparently documented rather than proprietary black boxes. Eighty constituents spanning fashion and leather goods, watches and jewelry, spirits, and luxury hospitality give a genuinely comprehensive read on the listed luxury economy rather than a narrow fashion-only slice, and the annual rebalancing keeps the composition current as the sector's leadership shifts. Its role as the underlying benchmark for investable products like the Amundi ETF gives it real-world utility beyond being a reference statistic, and related variants such as the decrement and capped indices show S&P has built out a genuine product family around the theme rather than a single flagship. The index itself makes no investment decisions and carries no opinion on luxury sector prospects, which is exactly the point of a benchmark, but that also means it offers less interpretive value than research-driven products like the Altagamma-Bain monitor.
