The capital market is a means of connecting business actors who need funds and people who have excess funds to invest. Researchers see that public interest, especially students, to invest is still very low even though students should be a part of society that has a lot of opportunities and has the potential to become investors in the capital market for the future.

The data used in this study is primary data derived from responses to questionnaires which were distributed to 100 respondents who are students of the Faculty of Economics and Islamic Business (FEBI) IAIN Parepare who are the objects of this research.
