Fears that the sovereign debt crisis could soften an already weak economic recovery in Europe and the United States caused big trouble on the global financial markets this month.
Many auto stocks took a beating while others did fairly well despite the mad wave of selling.
Volkswagen was one of the more fortunate auto companies. Its market capitalization declined just 4 percent to 50.3 billion euros because of strong sales in China, the United States and Brazil.
BMW's stock value fell 15 percent this month, which is worse than VW's decline but much better than the 32 percent market cap dip Daimler faced during the month, data from Morgan Stanley investment bank shows.
Among the biggest market cap losers between July and August were Fiat (-40 percent), Renault (-36 percent) and PSA/Peugeot-Citroen (-35 percent).
To put the magnitude of those declines into perspective consider this: the French and Italian automakers' combined value is now just one-third as much as VW Group's (17.4 billion euros compared with 50.3 billion). A month ago, the combined value of Fiat, PSA and Renault was a bit more than half that of VW Group.
Because of the atrocious August, Europe's six largest listed automakers lost a combined 36.1 billion euros in market capitalization.
