  1. 6. Optimal Capital Structures under the Vasicek Stochastic Interest Rate Model

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Oscar Danielson; Tom Hagéus; [2023]
    Nyckelord :Vasicek model; stochastic interest rate model; optimal capital structures; tax benefits; bankruptcy costs; transaction costs; optimal leverage ratio; optimal debt maturity; Vasicekmodell; stokastisk räntemodell; optimala kapitalstrukturer; skattefördelar; konkurskostnader; transaktionskostnader; optimal belåningsgrad; optimal löptid;

    Sammanfattning : This study applies the Vasicek stochastic interest rate model in order to determine optimal capital structures for listed firms. A Swedish interest rate data set is used to estimate Vasicek model parameter that are reliable and independent of initial start values. LÄS MER

  3. 7. Artificial Intelligence for Option Pricing

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Emil Hietanen; [2022-06-19]
    Nyckelord :Options; calls; puts; pricing; artificial neural networks; models; volatility; comparison;

    Sammanfattning : This thesis addresses the issue of vulnerable underlying assumptions used in option pricing methodology. More precisely; underlying assumptions made on the financial assets and markets make option pricing theory vulnerable to changes in the financial framework. LÄS MER

  4. 8. Pricing European Options with the Black-Scholes and Monte Carlo Methods: a Comparative Study

    Kandidat-uppsats,

    Författare :Isak Meding; Viking Zandhoff Westerlund; [2022-04-07]
    Nyckelord :Option pricing; Black-Scholes; Monte Carlo simulation; Jump Diffusion process;

    Sammanfattning : Option pricing is a central concept in finance. Since F. Black and M. Scholes in troduced their formula for pricing options in 1973 it has been widely adopted, but it has also been proven to have some limitations in its inherent assumptions and thus subsequent performance.

  5. 9. Financial Modelling Using Fractional Processes And The Wiener Chaos Expansion

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Olof Hummelgren; [2022]
    Nyckelord :fractional Brownian motion; fBM; applied mathematics; Wiener chaos expansion; Wick product; Hurst parameter; fraktionell Brownsk rörelse; tillämpad matematik; Wiener kaosexpansion; Wickprodukt; Hurstparameter;

    Sammanfattning : The aim of this thesis is to simulate stochastic models that are driven by a fractional Brownian motion process and to apply these methods to financial applications related to yield rate and asset price modelling. Several rough volatility processes are used to model the asset price and yield dynamics. LÄS MER

  7. 10. Performance of Stochastic Volatility and GARCH Models in Different Market Regimes

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Felix Viitanen; Erik Lundgren; [2022]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Reliable methods for estimating financial return volatility are crucial in many areas of trading and investing. Two such frameworks, the GARCH and SV, have been of particular interest to academics and practitioners alike. The GARCH model describes the variance of the current innovation as a function of the actual sizes of the previous innovations. LÄS MER
