The Dow Jones Industrials (DJINDICES:^DJI) have taken a big hit over the past two weeks, including two declines in the past five trading sessions of 1,000 points or more. Even after Friday's bounce, the Dow has fallen over 2,400 points, and its close on Thursday represented more than a 10% drop, meeting the definition of a correction for the average.

As you can see, declines in Asian markets have tended to be larger, in part because they were closed when the U.S. rebounded on Friday. The drops in European markets have tended to be more modest. Interestingly, even some emerging markets have outperformed the Dow.

The key message for investors is that the days of a contraction affecting only a single country are now largely over. You might see slight differences in just how much one country pulls back compared to another, but the globalization of the markets means that bad news tends to make itself felt around the world. That makes it important to know how to react constructively when markets dive.
