  abstract     = {{This thesis examines whether implied volatility derived from Swedish equity options provides superior predictive information relative to historical volatility for future realized volatility and stock returns, and whether this information improves portfolio risk outcomes. Using monthly option and stock data for OMXS30 firms, the study applies predictive regressions and constructs minimum variance portfolios based on implied volatility and historical volatility. The results show that implied volatility consistently outperforms historical volatility in forecasting realized volatility and exhibits stronger return predictability, while historical volatility shows no return predictive power. These forecasting gains translate into economically meaningful portfolio improvements, as an implied volatility-based minimum variance portfolio achieves lower realized variance and downside risk than standard benchmarks. The findings highlight the practical relevance of implied volatility for risk management in the Swedish equity market, extending prior evidence beyond U.S. equity markets.}},
