Luxury-goods giant LVMH Moet Hennessy Louis Vuitton said on Tuesday that third-quarter sales jumped 18%, an indication that high-end spenders shrugged off the market turbulence and economic uncertainty that clouded the summer.

LVMH--the group behind brands such as Louis Vuitton, Veuve Clicquot and Sephora--said revenue rose to €6.01bn from €5.11bn a year earlier. The figure was boosted by the acquisition of Italian jeweler Bulgari, which closed earlier this month. Yet stripping out acquisitions and exchange rate fluctuations, quarterly sales still increased 15%.
