Abstract
This study analyzed market risk of an international
investment portfolio by means of a new
methodological proposal based on Value-at-
Risk, using the covariance matrix of multivariate
GARCH-type models and the extreme value
theory to realize if an international diversification
strategy minimizes market risk, and to determine
if the VaR methodology adequately captures
market risk, by applying Backtesting tests. To
this end, we considered twelve international
stock indexes, accounting for about 62% of the
world stock market capitalization, and chose the
period from the Dot-Com crisis to the current
global financial crisis. Results show that the
proposed methodology is a good alternative to
accommodate the high market turbulence and
can be considered as an adequate portfolio risk
management instrument.
