Investing in particular countries is riskier than investing in world stocks. The timing of buying and selling is often crucial. It is difficult to predict whether a particular region will do better or worse than the world market.

But there is one thing we know for sure, and that is the number of days people work in a particular year. This number varies a little bit from year to year.

As we all know the US economy is in terribly bad shape. But watch the US economy in 2010, when the public holidays Juneteenth, Independence Day, Christmas and New Year (2011) are all on a weekend day. That should have a positive effect on the US economy. The fact that Christmas 2010 and New Year 2011 will be on weekend days might even affect the economies of all developed countries.
