Decathlon has again come in first in an annual ranking of the world’s 500 largest retailers in any sector compiled by OC&C Strategy Consultants. The French-based sporting goods retailers has placed in the top 10 every year since the first edition of the index. Second and third place went to Picard and Grand Frais, both of which are French retailers of food. Amazon returned to the top 10 by placing ninth. The index is based on a survey of 30,000 consumers worldwide, 4,500 of them in France. In OC&C’s analysis, consumers were keen this year on omni-channel retailing, exclusive offers and corporate engagement with sustainable development. The decline of hard discounters suggests a preference for quality over price. At the same time, Amazon’s rise seems to be anomalous, as generalist platforms seem to be losing popularity in some countries. Founded in 1987, OC&C has offices on four continents, advises companies and private-equity funds, and specializes in the mass market, distribution, the media and business services.
