Indonesian stocks or USD ??

I have a very interesting data here. I got the data from yahoo finance and www.exchange-rates.org. The data is about the historical prices of the Jakarta Composite Index (IHSG) and the USD / IDR historical rate. I took 3 November 2008 as the basic data for my analysis. The interesting issue is that obviously if we put our money in USD, the return that we get today (12 February 2009) is significantly higher than if we invest in the Jakarta Composite Index (IHSG). Here is the detail :
