Abstract

This paper aims to investigate the behavioral factors that influence individual investment decision making at a developing country stock market; the Sudanese Stock Exchange Market.

The factors that have a significant impact on individual investment decision making process include Representativeness, Overconfidence, Anchoring, Historical cost of stock, Customer preferences, Loss aversion, Mental accounting, Other investors¡¯ trading volume, and Quick reaction to changes in other investors ¡®decisions. Factors that have an insignificant impact include Availability bias, Change in stock prices, Regret aversion, and Other investors¡¯ decisions and choices.
