Nauki o Finansach, 2021, vol. 26, no. 1, s. 37-55 N2 - The article is devoted to the assessment of the accuracy of the binomial model in forecasting the value of capital using the Back-Test approach. In this study, the Monte Carlo method was used to simulate the value of capital using real volatility distributions of stock returns. Based on the analysis of the variability of the stocks returns profile, a generator of real distributions was built, which was used for the Monte Carlo simulation. The results of the study confirmed the high quality and accuracy of the method proposed by the author. Due to the potentially large benefits for company management and investors that come from the measurement quality, according to the methodology presented in the study, it is worth extending this trend in theory and practice. This article is mainly directed to business practitioners engaged in the analytical process of company valuation in restructuring, merging and acquisition of enterprises, and building an investment portfolio L1 - http://www.dbc.wroc.pl/Content/112252/Krysiak_The_accuracy_of_the_equity's_forecast_in_the_option.pdf M3 - artykuł L2 - http://www.dbc.wroc.pl/Content/112252 PY - 2021 KW - option model KW - binominal model KW - Monte Carlo simulation KW - real volatility distribution KW - Back-Test KW - forecast of the enterprise equity KW - model opcyjny KW - model dwumianowy KW - symulacja Monte Carlo KW - rozkład rzeczywisty zmienności cen akcji KW - prognoza kapitału przedsiębiorstwa C1 - Pewne prawa zastrzeżone na rzecz Autorów i Wydawcy A1 - Krysiak, Zbigniew PB - Wydawnictwo Uniwersytetu Ekonomicznego we Wrocławiu C6 - Dla wszystkich zgodnie z licencją LA - eng CY - Wrocław ID - DOI: 10.15611/fins.2021.1.03 T1 - The accuracy of the equity’s forecast in the option model simulated by real volatility distribution UR - http://www.dbc.wroc.pl/dlibra/publication/edition/112252 T2 - Dokladność prognozy kapitału w modelu opcji z symulacją rzeczywistej zmienności ER -
