Analýza vlivu behaviorálních zkreslení na investiční rozhodování jednotlivců v České republice

This bachelor’s thesis analyzes the impact of behavioral biases on individual investment decision-making in the Czech Republic, as understanding these phenomena is essential for explaining deviations from rational behavior in financial markets. The aim of the thesis is to identify the presence of selected behavioral biases and to assess the influence of demographic and investment factors on their intensity. The research is based on an online anonymous survey conducted among 161 respondents and subsequent statistical analysis, including two-tailed t-tests and multiple linear regression using the ordinary least squares (OLS) method. The results show that loss aversion, overconfidence, the endowment effect, and the illusion of control are statistically significant among Czech investors, while herding effect, anchoring, confirmation bias, and hindsight bias were not confirmed. The analysis further reveals that the intensity of these biases is influenced mainly by gender, age, investment horizon, and invested capital. The findings highlight the importance of behavioral finance in understanding investment behavior and indicate practical implications for investment advisory and financial education.
