  1. 1. Portfolio Risk Modelling in Venture Debt

    Master-uppsats, KTH/Matematisk statistik

    Författare :John Eriksson; Jacob Holmberg; [2023]
    Nyckelord :Startup Default Probability; Venture Debt; Gaussian Copula; Value-at-Risk; Expected Shortfall; Exposure at Default; Loss Given Default; Forecast; Linear Dynamic System; ARIMA Time Series; Monte Carlo Simulation; Linear Regression; Central Limit Theorem;

    Sammanfattning : This thesis project is an experimental study on how to approach quantitative portfolio credit risk modelling in Venture Debt portfolios. Facing a lack of applicable default data from ArK and publicly available sets, as well as seeking to capture companies that fail to service debt obligations before defaulting per se, we present an approach to risk modeling based on trends in revenue.

  3. 2. Modelling Risk in Real-Life Multi-Asset Portfolios

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Karin Hahn; Axel Backlund; [2023]
    Nyckelord :Risk modelling; multi-asset portfolios; risk factor models; time series analysis; regression; Riskmodellering; finansiella portföljer; riskfaktormodeller; tidsserieanalys; regression;

    Sammanfattning : We develop a risk factor model based on data from a large number of portfolios spanning multiple asset classes. The risk factors are selected based on economic theory through an analysis of the asset holdings, as well as statistical tests. LÄS MER

  4. 3. Risk Modeling of Sustainable Mutual Funds Using GARCH Time Series

    Master-uppsats, KTH/Matematisk statistik

    Författare :Erik Malmgren; Annie Zhang; [2020]
    Nyckelord :GARCH; ARMA-GARCH; Risk Modeling; Time Series; Volatility; Value at Risk; Sustainable Investments; SRI; ESG; Mutual Funds; Morningstar; GARCH; ARMA-GARCH; Riskmodellering; Tidsserie; Volatilitet; Value at risk; Hållbara investeringar; SRI; ESG; Fonder; Morningstar;

    Sammanfattning : The demand for sustainable investments has seen an increase in recent years. There is considerable literature covering backtesting of the performance and risk of socially responsible investments (SRI) compared to conventional investments. LÄS MER

  5. 4. Risk Modelling in Payment Guarantees

    Master-uppsats, KTH/Matematisk statistik

    Författare :Gutstav Kratz; [2018]
    Nyckelord :;

    Sammanfattning : The Swedish Export Credit Agency (EKN) issues payment guarantees to Swedish companies who face the risk of non-payments in export transactions. Commitments are typically correlated, as defaults of companies are driven by other factors than factors specific to that company, such as the economic cycle or the regional conditions. LÄS MER

  7. 5. Optimal mass transport: a viable alternative to copulas in financial risk modeling?

    Master-uppsats, KTH/Matematik (Inst.)

    Författare :Johan Orrenius; [2018]
    Nyckelord :Optimal mass transport; Financial risk; Copulas;

    Sammanfattning : Copulas as a description of joint probability distributions is today common when modeling financial risk. The optimal mass transport problem also describes dependence structures, although it is not well explored. This thesis explores the dependence structures of the entropy regularized optimal mass transport problem. LÄS MER
