The U.S. dollar is under downward pressure. Investors must hedge themselves against the depreciation of the U.S. dollar.

Most stock market investors forget about currency risk. They invest in their nation's stocks, not paying attention to the fact that, internationally, they may be losing money when their domestic stock market rises.

We are now clearly at the beginning of a new era: open borders for capital. Any investor who does not pay attention to investments that are denominated in a currency other than his national currency is going to lose money he could have made.

Diversify. This means foreign opportunities.
