This study aims to explore the impact of a number of prominent behavioral finance variables covered by the financial literature (overconfidence, loss aversion, risk perception and herding) that may affect the stock investment decision-making at Amman Stock Exchange (ASE), as well as determining which of these variables has the relative importance. The importance of this study stems from the fact that local studies focusing on the issue of behavioral finance are rare and therefore, the researchers expect that such study will enrich awareness in this domain.
