Loss aversion is a cognitive bias where the emotional pain of losses outweighs the pleasure of equivalent gains, as defined by Kahneman (2011) and central to Prospect Theory by Kahneman and Tversky. This bias, consistent with prospect theory, drives investors to hold declining stocks longer than rational, fearing to realize losses, a pattern termed the disposition effect and evidenced in Odean's 1998 study reluctance to realize losses. It leads to poor decisions like avoiding lucrative investments or overly conservative strategies, per Ariely and Loewenstein (2006) and Thaler & Sunstein (2008), affecting retail investors alongside biases like overconfidence and herding, as noted in studies such as Shah and Malik (2021). Beyond investing, it explains real estate persistence, homeowner pricing, consumer hesitation on returns, and cash hoarding, while positively channeled for budgeting. Mitigation includes education, diversification, predetermined exit strategies, and advisor interventions focusing on objective evaluation. Some research, like Gal and Rucker (2018), suggests situational dependence, and Christoph (2020) notes overestimated impact. Overall, understanding loss aversion, per behavioral economics research, promotes better financial outcomes.
