Behavioral finance has provided a variety of explanations for individual investors’ financial performance that focus on behavioral biases, and information systems (IS) have developed theories about financial information system issues from the system management perspective. This study examines 2,726 proprietary online individual investors’ stock trading accounts and analyzes the field survey responses of a group of 178 individual investors. The study investigates different IS-related constructs and their association with individual investors’ financial performance. The results show that IS constructs that could be used to examine the relationship between mobile stock trading platforms and individual investors’ financial performance are satisfaction and perceived usefulness. The results also reveal that the perceived usefulness of IS mobile stock trading platforms in the risk-seeking individual investors’ group is significant and positively associated with their financial performance.
