This study examines the role of regulatory focus and additional information on risk preferences in investment choice using an experimental approach. The findings reveal that situational regulatory focus plays an important role in influencing investment choice. In particular, a congruent promotion-focused image and related message increases risk-taking behavior in terms of choice for stocks rather than fixed deposits, whereas the reverse is true for a congruent prevention-focused image and related message. However, this relationship depends on the amount of information available during the decision-making process, and regulatory focus has a stronger impact on investment choice under the condition without additional financial information.
