Shares of LVMH Moët Hennessy Louis Vuitton SE dropped almost 9% to €285.70 in the first few minutes after the French stock market opened, Reuters reported March 25.

Traders reportedly suspect that a "fat-finger" error, which is a human error such as a misclick or inputting wrong data, caused the shares to slide.

LVMH recovered most of the value it lost by the mid-morning, the report said.

The luxury firm and Euronext, which operates France's CAC 40 Stock Exchange, reportedly were not immediately available for comment.
