The Effect Of Traders’ Cognitive Biases On Psychological Attributes And Confidence And Its Solutions: An Experimental Study

Pedagang saham cenderung menbuat keputusan berdasarkan intuisi mereka yang menjurus bias kognitif seperti “confirmation bias”, “self-serving bias” dan “hindsight bias”. Bias ini membuat pedagang saham mempamerkan sifat-sifat psikologi terlalu yakin seperti “miscalibration”, “better than average effe...
