"The negative reaction to last night’s Tesla numbers, along with a pledge to cut prices further has weighed on the European auto sector, with losses for BMW (BIT:BMW), Renault (EPA:RENA), Stellantis (LON:0QXR), and Volkswagen (ETR:VOWG_p) over concerns that already thin margins will get even thinner, as prices get cut further.
"The fact that demand is falling for electric cars isn’t helping either given that the economic case for owning one has declined along with falling petrol prices."
In economic news, German producer prices rose less than expected in March, posting the smallest year-on-year increase since June 2021, according to official data.
Producer prices of industrial products were up 7.5% on the same month last year, the Federal Statistical Office reported, against expectations of a 9.8% year-on-year rise.
Energy prices were still mainly responsible for the year-on-year increase, up 6.8%. Excluding energy, producer prices rose 7.9% in March on the year. Compared to February, prices fell by 2.6%, posting the sixth consecutive decline.
The statistics office added that the results were preliminary and would have to be revised because a price brake on electricity and gas that comes into effect in March distorts calculations.
