Abstract:
This study is aimed to measure the value of value at risk using variance covariance historical simulation
model. The research object used in this research is the foreign exchange rate published in the Bank of
Indonesia. Samples are consist of 200 foreign exchange rate published in Bank of Indonesia. the data
used is the middle rate of exchange for the year of 2012. the measurement of value at risk on this
research is using confidence level at 95% and time horizon of 5 days, 10 days, and 15 days.
Determination of the proportion of funds in the portfolio formation using the value at risk is using the
proportion funds division evenly and using solver in Microsoft Excel 2007.The result of this research
shows that there's the differences of measurement result of certain risk between variance covariance and
historical simulation models, which the value of value at risk with historical simulation model is fewer
than the value at risk with variance covariance model. In the portfolio calculation, there's the differences
in value at risk of foreign exchange rate portfolio result, between variance covariance model and
historical simulation model. using solver resulting in value at risk of foreign exchange rate portfolio have
a fewer value than value at risk of foreign exchange rate portfolio that's not using solver
