TY - JOUR ID - 10429 AU - Sohns, Moritz PY - 2022 TI - Utility indifference pricing in the Heston model: pricing, hedging and shortcomings PB - Vysoká škola finanční a správní CY - Praha SN - 9788074082504 KW - Heston model KW - stochastic volatility KW - derivatives pricing KW - option pricing KW - pricing simulation UR - https://www.vsfs.cz/prilohy/konference_doktorandu_na_vysoke_skole_fi.pdf N2 - This paper deals with the Heston model's utility indifference pricing method via the exponential utility function. We illustrate the main properties, review the existing literature and elaborate on the idea behind the pricing method and control. The main results of this paper are a pricing equation for the model, an equation for the optimal hedging strategy in the model, an illustration of why short positions must not appear in practice when applying the utility indifference approach, which is a contradiction to the observed real-world trading and a simulation of the price process, calculation of the corresponding derivative prices and a comparison of the different hedging strategies. The simulation together with the result about the absence of short positions hints that utility indifference pricing should be treated with caution when applied in practice in the real world. ER -
