This study investigates the interactive effects of brand logo dynamism and product types—specifically, hedonic and utilitarian—on market performance. Mixed methods are employed, including a pilot study that analyzes the association between logo dynamism and product types from the most valuable brands on Forbes’ list, an event study of abnormal stock returns caused by logo-dynamic changes in the Hong Kong stock market, and two experiments. The results reveal that hedonic products with high-dynamic logos and utilitarian products with low-dynamic logos exhibit better market performance. Quality inference, which is based on information processing and inference theory, mediates this effect. These results provide a better understanding of the role of quality inference in logo design effectiveness, emphasizing the importance of designing logos that appeal to customers’ needs and expectations.
