NEW YORK (AFP)
Tesla shares tumbled more than eight percent early Thursday after it reported lower profits and CEO Elon Musk warned the company faced more potentially "rough" quarters ahead.
Near 1350 GMT, Tesla shares were at $30.50, down 8.1 percent.
Tesla reported second-quarter profits of $1.2 billion, down 16 percent from the year-ago level, its third quarter in a row in which profits fell.
