The shares of Gucci owner Kering fall

Shares in Gucci owner Kering have tumbled after the French luxury goods giant issued a profit warning following a drop in sales of its flagship brand.
Kering shares sank 8.5 percent to 320.55 euros after the opening bell in Paris, hitting their lowest level in six years.
The group's share price has fallen almost 20% since the start of the year.
On Tuesday, Kering said its sales fell 11% in the first quarter, citing difficult market conditions, especially in China, a major consumer of luxury goods.
The company cautioned that it expects its operating income to fall between 40 and 45 percent in the first half of the year. /BGNES
