Individual investors exhibiting irrational behaviors may encounter a difficult situation in financial markets. Investor trends, also known as behavioral trends, have been introduced under different headlines in different studies. Overconfidence, representation, anchoring, regret aversion, and herding were included in the research study. In this study, it was aimed to determine the order of importance of investor biases of individual investors trading in Borsa Istanbul. For this purpose, a survey questionnaire was applied to individual investors trading in BIST. Analytical Hierarchy Process was utilized in testing the research model. A total of 411 participants contributed to the study. As a result of the study, regret aversion bias and overconfidence bias were the leading biases to which individual investors attached importance. However, the criterion (C41) “I feel sorrow for the long-losing stocks I hold.” was found to rank highest among all sub-criteria. This sub-criterion is part of regret aversion bias. Regret aversion bias was also the main criterion ranking highest among all criteria. Upon considering the other sub-criteria of regret aversion bias; C42, C43, and C44 sub-criteria were found to rank second, fourth, and eleventh, respectively. C12 criterion, which ranked third, was seen to belong to overconfidence bias, and this bias ranked second among the main criteria. This research would contribute to a better comprehension of the behavioral biases that affect the decision-making of individual investors trading in BIST. The obtained results of the study are thought to contribute to the behavioral finance literature.

İrrasyonel davranışlar sergileyen bireysel yatırımcılar finansal piyasalarda zor durumlarla karşılaşabilmektedir. Davranışsal eğilimler olarak da bilinen yatırımcı eğilimleri, farklı çalışmalarda farklı başlıklar altında tanıtılmıştır. Aşırı güven, temsiliyet, çıpalama, pişmanlıktan kaçınma ve sürü eğilimi araştırma çalışmasına dâhil edilmiştir. Bu çalışmada Borsa İstanbul’da işlem gören bireysel yatırımcıların yatırımcı önyargılarının önem sırasının belirlenmesi amaçlanmıştır. Bu amaçla BIST’te işlem yapan bireysel yatırımcılara anket uygulanmıştır. Araştırma modelinin test edilmesinde Analitik Hiyerarşi Sürecinden yararlanılmıştır. Araştırmaya toplam 411 katılımcı katkı sağlamıştır. Araştırma sonucunda bireysel yatırımcıların önem verdiği önyargıların başında pişmanlıktan kaçınma eğilimi ve aşırı güven eğilimi gelmektedir. Ancak (C41) kriteri “Uzun süredir kayıpta olan hisse senetlerim için üzüntü duyuyorum.” tüm alt kriterler arasında en üst sırada yer aldığı görülmüştür. Bu alt kriter pişmanlıktan kaçınma yanlılığının bir parçasıdır. Pişmanlıktan kaçınma yanlılığı da tüm kriterler arasında en yüksek sırayı alan ana kriter olmuştur. Pişmanlıktan kaçınma yanlılığının diğer alt kriterleri de dikkate alındığında; C42, C43 ve C44 alt kriterlerinin sırasıyla ikinci, dördüncü ve onbirinci sırada yer aldığı görüldü. Üçüncü sırada yer alan C12 kriterinin aşırı güven yanlılığına ait olduğu görüldü ve bu yanlılık ana kriterler arasında ikinci sırada yer aldı. Bu araştırma, BIST’te işlem yapan bireysel yatırımcıların karar vermelerini etkileyen davranışsal önyargıların daha iyi anlaşılmasına katkıda bulunacaktır. Araştırmadan elde edilen sonuçların davranışsal finans literatürüne katkı sağlayacağı düşünülmektedir.
