This study examines the antecedents of electronic service acceptance in the context of Internet securities trading. The survey results, from a sample of securities investors show five antecedents that have a positive impact on perceived usefulness: ease of use, information quality, accessibility, trust, and flow-control of the securities trading process. Respondents see the highest benefit in the flow-control of the securities trading processes via the Internet channel. Investors prefer to have the freedom to control details of the trading process when trading securities. In this context, the results suggest that trust may be a better antecedent to perceived usefulness and attitude toward usage, rather than a parallel, direct determinant of intention to use.
