  1. 1. Time Dependencies Between Equity Options Implied Volatility Surfaces and Stock Loans, A Forecast Analysis with Recurrent Neural Networks and Multivariate Time Series

    University essay from KTH/Matematik (Avd.)

    Author : Simon Wahlberg; [2022]
    Keywords : RNN; LSTM; GRU; vector autoregression; implied volatility surface; stock loan; equity options; multivariate time-series analysis; financial mathematics.; Rekursiva neurala nätverk; LSTM; GRU; VAR; implicerade volatilitetsytor; aktielån; aktieoptioner; multidimensionell tidsserieanalys; finansiell matematik.;

    Abstract : Synthetic short positions constructed by equity options and stock loan short sells are linked by arbitrage. This thesis analyses the link by considering the implied volatility surface (IVS) at 80%, 100%, and 120% moneyness, and stock loan variables such as benchmark rate (rt), utilization, short interest, and transaction trends to inspect time-dependent structures between the two assets.

  3. 2. On the Value at Risk Forecasting of the Market Risk for Large Portfolios based on Dynamic Factor Models with Multivariate GARCH Specifications

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Axel Eurenius Larsson; [2022]
    Keywords : Dynamic factor model; Value at Risk; Forecasting; Conditional Correlation GARCH.;

    Abstract : Market risk is the risk of capital loss due to unexpected changes in market prices. One risk measure used to estimate market risk is Value at Risk (VaR). The common historical simulation methodology of VaR forecasting usually does not capture the time-varying volatilities associated with financial data. READ MORE

  6. 5. Portfolio Performance Optimization Using Multivariate Time Series Volatilities Processed With Deep Layering LSTM Neurons and Markowitz

    University essay from KTH/Matematisk statistik

    Author : Aron Andersson; Shabnam Mirkhani; [2020]
    Keywords : Recurrent Neural network RNN ; long short-term memory LSTM ; portfolio optimization; markowitz; exponential moving average; sharpe ratio; heteroskedasticity; Markowitz;

    Abstract : The stock market is a non-linear field, but many of the best-known portfolio optimization algorithms are based on linear models. In recent years, the rapid development of machine learning has produced flexible models capable of complex pattern recognition. READ MORE
