LVMH, Kering, and Hermès reported Q3 results showing the first sequential revenue acceleration since Q2 2024, with aggregate quarterly sales across the $340bn global luxury sector rising 3.2% year-over-year after two quarters of contraction. LVMH posted €19.96bn in Q3 revenue, a 2.8% organic gain, while Hermès delivered €3.7bn at 10.1% growth. The delta: US high-net-worth spending held flat at elevated levels, and Chinese mainland demand stopped contracting for the first time in seven quarters.

The American wealth effect carried the quarter. S&P 500 gains through September lifted US luxury spending by an estimated 6-8% in dollar terms, concentrated in handbags, watches, and jewelry. European houses with direct US retail exposure—LVMH's Tiffany, Richemont's Cartier—saw mid-single-digit comparable-store growth in North America. Meanwhile, China stabilized without recovering. Mainland sales were flat to down 1% for most houses, but the sequential deceleration slowed sharply. Pragmatic Chinese consumers shifted spending to Hainan duty-free and Hong Kong, where LVMH noted 15% growth in travel retail. The sector's dependence on aspirational Chinese cohorts remains a structural overhang, but the bleeding stopped.

The rebound matters because luxury is a capital-deployment bellwether for family offices and sovereign wealth pools. European luxury stocks are 18-22% cheaper than their five-year average forward P/E multiples, and Q3 results validate the thesis that 2024 was a cyclical trough, not a secular break. Allocators who rotated into US tech during the luxury drawdown now face a valuation arbitrage: LVMH trades at 21x forward earnings despite 14% average annual revenue growth over the past decade, while the Nasdaq-100 trades at 28x with decelerating sales comps. The Q3 print gives cover to re-enter European luxury exposure at defensible valuations. Family offices with mandate flexibility are already layering into Hermès and Brunello Cucinelli, which posted 11.3% nine-month growth and raised full-year guidance to 12%.

Operators and allocators should watch two specific markers. First, the November 11-17 Singles' Day sales data from Tmall and JD.com will clarify whether Chinese consumer pragmatism translates into actual spending velocity or merely slower decline. Early reports suggest luxury participation in Singles' Day promotions increased for the first time in three years, a subtle but meaningful shift in brand willingness to discount. Second, LVMH's full-year results in late January will include granular US regional data, particularly for Tiffany and Sephora, which together represent $14bn in annual revenue. If US comparable-store sales hold above 5% in Q4, the sector's forward estimates reset higher by 8-10%.

The luxury sector's stabilization arrives without the Chinese consumer recovery Western analysts expected, which means the next leg depends entirely on whether US wealth persists and whether European houses can defend pricing power in a world where aspirational cohorts have already de-rated the category.
