Benz on Thursday cut its full-year profit margin for the second time in less than two months, after overall sales volume fell in China. The ongoing weakness of the Chinese market for luxury cars prompted the Stuttgart carmaker to trim its outlook after having already done so as recently as July.

Mercedes-Benz Group AG shares fell the most in four years after a deepening slowdown in China prompted the world’s biggest luxury-car maker to cut its outlook.

Chief executive Ola Källenius told analysts on Friday that the company’s issues stemmed “mainly [from] China” but added that in other markets, such as Europe, Mercedes-Benz was also still feeling “the [impact] of higher interest rates”.
