The Gucci owner Kering's share falls by around 4 percent on the Paris stock exchange on Monday.
So far this year, the share has plummeted by 43 percent and the value is now at its lowest level since 2017.
Luxury brands have generally had a tough time on the stock exchange in recent months. One explanation is poor demand from Chinese consumers, and Gucci is among the hardest hit.
In a comment, analysts at Barclays write that the downturn in the Chinese economy has made Chinese consumers more selective when shopping for luxury, and that they are opting for brands that are even more exclusive instead of Gucci.
