Shares of Kering plunged on Friday after the firm announced that Demna Gvasalia would take the reigns as new artistic director of its ailing Gucci fashion line.

Kering lost around $3 billion in stockmarket value on Friday after the group chose in-house talent Demna to reinvigorate its Gucci label rather than hiring one of fashion's big-ticket names as chief designer.

The French luxury-goods company named Demna Gvasalia as the new artistic director of its flagship label Gucci, as the group seeks a brand turnaround amid a challenging market backdrop for luxury names.
