We dive into the psychological trap of holding onto losing assets simply because we own them. Using the classic Thaler and Kahneman experiments alongside real-world portfolio management failures, Lucas and Luna explore why investors struggle to sell underperforming stocks. We examine how emotional attachment overrides rational financial logic, leading to the disposition effect in daily trading. This episode breaks down specific behavioral patterns that cost millions and offers a framework for detaching ego from equity. If you have ever held a stock hoping it would break even rather than cutting losses, this analysis explains exactly why your brain is working against you. #BehavioralEconomics #InvestmentPsychology #DispositionEffect #LossAversion #PortfolioManagement #ThalerAndKahneman #EndowmentEffect #FinancialBias #MarketBehavior #RationalDecisionMaking #AssetAllocation #TradingStrategies #CognitiveBias #WealthBuilding #FexingoBusiness #BusinessPodcast #EconomicsDaily #LucasAndLuna Keep every episode free: buymeacoffee.com/fexingo
