Why Your Brain Treats an Investment Win as Skill Not Luck

In this episode, Lucas and Luna explore the psychological bias known as the self-attribution bias, where investors credit their wins to skill and blame losses on bad luck. They anchor the discussion on a 2023 study by behavioral economists at the University of Chicago, which tracked 8,000 retail investors over two years and found that those who exhibited strong self-attribution bias underperformed the market by an average of 3.2 percent annually. The hosts break down why this bias is particularly dangerous in a bull market, how it fuels overconfidence and overtrading, and what investors can do to counteract it. Lucas references the famous study by Barber and Odean on overconfidence, and Luna shares a personal anecdote about a friend who mistook a lucky meme-stock run for genius. They wrap up with practical mental models for keeping ego out of your portfolio decisions. #SelfAttributionBias #BehavioralFinance #InvestorPsychology #Overconfidence #Overtrading #BullMarketMistakes #BarberAndOdean #UniversityOfChicago #RetailInvestors #LuckVsSkill #InvestmentBias #PortfolioManagement #MoneyMindset #Finance #FexingoBusiness #BusinessPodcast #PsychologyOfMoney #WealthThinking Keep every episode free: buymeacoffee.com/fexingo
