1. 1. Volatility Forecasting - A comparative study of different forecasting models.

   Kandidat-uppsats,

   Författare :Emil Sturesson; Anton Wennström; [2023-06-29]
   Nyckelord :Volatility; GARCH; EGARCH; t-GAS; HAR-RV; Realized GARCH; Volatility Forecasting; Volatility Modelling;

   Sammanfattning : This study evaluates the out-of-sample forecasting performance of different volatility mod- els. When applied to XACT OMXS30, we use GARCH(1,1), EGARCH(1,1), and t- GAS(1,1) to forecast squared daily returns while Realized GARCH(1,1) and HAR-RV are used to forecast Realized Variance. LÄS MER

3. 2. The Intertwining of Sectoral Stock Market Volatility and Macroeconomic Fundamentals - A study of Sweden's sectoral indices

4. 3. CAN DEEP LEARNING BEAT TRADITIONAL ECONOMETRICS IN FORECASTING OF REALIZED VOLATILITY?

   Master-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Filip Björnsjö; [2020]
   Nyckelord :Deep Learning; Econometrics; volatility;

   Sammanfattning : Volatility modelling is a field dominated by classic Econometric methods such as the Nobel Prize winning Autoregressive conditional heteroskedasticity (ARCH) model. This paper therefore investigates if the field of Deep Learning can live up to the hype and outperform classic Econometrics in forecasting of realized volatility. LÄS MER

5. 4. Forecasting Exchange Rate Volatility. Applying HAR models and Implied Volatility in SEK denominated markets

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Anton Agermark; Visar Hoti; [2016-10-04]
   Nyckelord :forecasting; implied volatility; realized volatility; jump process; bipower variation; tripower variation; high-frequency data; FX;

   Sammanfattning : In this paper we study a set of models' forecasting accuracy of realized volatility in two SEK denominated exchange rates, EUR/SEK and USD/SEK, with the purpose to analyze if ex-post or ex-ante forecasting models produce the most accurate forecasts. High-frequency exchange rate data is employed in order to construct the ex-post Heterogeneous Autoregressive Model of Realized Volatility, HAR-RV, as well as a modi ed model using the bipower and tripower variation to separate the continuous sample path (C) and the jump component (J) of realized volatility, HAR-CJ.

7. 5. Crude Volatility - Investigation of the HAR-RV model and Implied volatility in Brent Crude Futures

   Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

   Författare :Niklas Lindeke; [2015]
   Nyckelord :Volatility; Brent Crude; Oil; HAR-RV; Implied Volatility; Business and Economics;

   Sammanfattning : This thesis investigates the relationship between the quantitative volatility model HAR-RV and the qualitative volatility implied in the option pricing formula. Using OLS regression with Newey-West to estimate the HAR model, strong predictive characteristics where obtained, as well as observing a very high informational relationship between the two model.
