Köksal, Emre Ahmet

In this paper, realized volatility of a selection of BIST Indices are forecasted with Heterogeneous Autoregressive Model (HAR) and its variations. For this purpose, ticks between 2001 and 2021 are used to generate 5-minute returns, which formed the basis for calculations of realized volatility and other realized measures. In the study, rolling windows are utilized for forecasting the volatility of one day ahead. These predictions are then compared to the actual realized volatilities. The study provides a thorough comparison of HAR-type models, and emphasizes the importance of underlying time s ...Daha fazlası

How systematic is default risk?

Dalgıç, Nihan

This study aims to provide an extensive analysis of systematic (market-wide) and systemic (sector-wide and industry-wide) components of the idiosyncratic default risk. We detect significant heterogeneity among the default risk structure of various industry groups. More specifically, the default probability of institutions affiliated with certain industry groups is more strongly linked to industry-wide risks while others are more heavily tied to sectorwide risks. We further show that systematic and systemic components of default risk alter also relative to up/down market cycles for each indust ...Daha fazlası
