ABSTRACT:The present paper analyses the relationship between the volume of transactions with futuresequity index products and the return volatility of their underlying assets. The study addressesthe case of five stock markets, members of the Euronext.liffe. We employ a frequency domainanalysis...

This paper analyzes the dynamics and determinants of the relative benefits of geographical and industry diversification over the last 30 years. First, we develop a new structural regimeswitching volatility spillover model to decompose total risk into a systematic and a country (industry)...

This work proposes an approach for estimating value at risk (VaR) of the Mexican stock exchange index (IPC) by using a combination of the autoregressive moving average models (ARMA); three different models of the arch family, one symmetric (GARCH) and two asymmetric (GJR-GARCH and EGARCH); and...

This paper investigates the impact of globalization and integration on the relative benefits of country and industry diversification. Unlike previous models, our factor model allows asset exposures to vary with both structural changes and temporary fluctuations in the economic and financial...

This note discusses some aspects of the paper by Hu and Tsay (2014), “Principal Volatility Component Analysis”. The key issues are considered, and are also related to existing conditional covariance and correlation models. Some caveats are given about multivariate models of time-varying...

The price of gold is influenced by a wide range of local and global factors such as commodity prices, interest rates, inflation expectations, exchange rate changes and stock market volatility among others. Hence, forecasting the price of gold is a notoriously difficult task and the main problem...

We investigate the role of jumps in transmitting volatility between foreign exchange markets (Engle, Ito, and Lin, 1990; Melvin and Peiers Melvin, 2003; Cai, Howorka, and Wongswan, 2008). We show that recently developed estimators have very different implications for the impact of jumps on exchange rate...

Oil is perceived as a good diversification tool for stock markets. To fully understand this potential, we propose a new empirical methodology that combines generalized autoregressive score copula functions with high frequency data and allows us to capture and forecast the conditional...

This paper examines the behavior of several implied volatility indexes in order to compare them with the volatility forecasts obtained from estimating a GARCH model. Though volatility has always been a prevailing subject of research it has become particularly relevant given the increasingly...
