Investors in vehicle makers lost money in the first quarter but those owning PSA/Peugeot-Citroen and DaimlerChrysler stock lost less than most, according to Automotive News Europe. The value of PSA's stock declined only 7.8% as it continued to increase its share of the new passenger-car market to 15.7% in the period from 15% a year earlier. The improvement was all due to Citroen with its successful C3 small car and the company's aggressive discounting campaign for other, older models.
