In this research, we will present a model of adaptive risk aversion by reference point in prospect theory. We funded many theoretical and researches are shown risk aversion is dependent on wealth. We used the out coming wealth from a portfolio optimization determine as the investor's reference point. Compatibility of the reference point with the wealth of portfolio performance at the end of the investment period is a measure to determine new risk aversion. After proposing an adaptive risk aversion measure, the model was implemented for 35 shares of the Tehran Stock Exchange market plus a risk-free asset during 7 investment periods, and finally, by solving the model and applying the genetic algorithm, the adaptive risk aversion was calculated.
