Abstract
In the science of finance and the world of investment, risk includes the probability of a threat to financial investments occurring, and the possible effects of that probability in the aftermath. As it can be understood from the definition, the literature has approached risk reactively and the risk has been handled as the effects after the risky event has occurred. However, risk-taking behavior deserves to be handled with a proactive approach, as it is a concept that has implications that are the subject of many different disciplines. Proactive handling of the risk undertaken by investors in financial markets is important in terms of showing the investor's risk acceptance limits and the factors that determine these limits. This study reveals the necessity of considering the risk-taking behavior of investors together with genetics. In this study, in which literature review was conducted, quantitative genetic methods and studies using molecular genetic methods were examined in detail. With these studies, the existence of genetic factors that can affect risk-taking behavior, which can be affected by many psychological and sociological factors such as personality, mood disorders, behaviors of the immediate environment, as well as basic demographic factors such as gender and age, has been revealed, both directly and indirectly by affecting psychological factors.
