For example, if you begin currency trading by buying euros with your U.S. dollars, either the euro will go up against the dollar or the dollar will go up against the euro.

Trading currencies can be dangerous business, but you don't face the so-called "market risk" presented by stocks or bonds. The foreign exchange market is always moving sideways.

Trading Currencies Adds Instant Diversification

If you're a wealthy investor with what you think is a well-diversified portfolio, you could be in for a surprise. Let's say you have stocks, bonds, CD's, and cash in a money market fund. If the American economy completely tanks, you could still lose out. This is why currency trading is a good strategy for investors.

Think You're New To Trading Currencies? It's Doubtful

Trading currencies is not as complex as some market pundits make it out to be. After all, almost everyone has been involved in currency trading at least once in their life. Have you ever gone to Canada and traded your U.S. dollars for Canadian dollars? If so, you've been involved in currency trading.

At it's root, this is what it means to trade currencies - exchanging your U.S. dollars for some other nation's money. As you get more experienced in trading currencies, and your currency portfolio becomes more diversified, you won't be limited to using U.S. dollars.

After all, if you have them, you could trade Swiss francs for Japanese yen, or Australian dollars for Brazilian real. Currency trading offers you almost unlimited options.

Trading Currencies Through the Forex

The forex is the most popular venue for currency trading. Although technically, the forex exists anywhere and any time two or more people are trading currencies, the term "forex" normally refers to an organized platform for currency trading, most commonly over the internet.

National governments and their central banks are the biggest currency traders through the forex. Large commercial banks and multi-national corporations also use the forex for currency trading, although their objectives are different.

Banks engage in currency trading as a business in its own right - they buy currencies on the open market and sell them as "currency exchanges" with a mark-up. Multi-national corporations trade currencies in order to hedge currency risk.

If a multi-national company does a lot of business in Japan but is worried that the yen will go down versus the euro, it can swap out of yen and into euros, for example.

You Can Trade Currencies Like The Big Corporations

Some individual investors use the forex in order to capitalize on small movements in foreign exchange rates. Although the potential rewards are high, so are the risks. Most investors are better off currency trading like the big corporations - to hedge risk.

For example, if your portfolio is full of U.S. investments that benefit from a strong dollar, consider using some of your excess cash to purchase euros or yen. Alternatively, you could buy foreign stocks, emerging market mutual funds, or even commodities like gold.

The idea is to diversify outside of the United States, so that in the event of a slow-down at home, your hard-earned assets are protected. Otherwise, the only currency trading you might be doing is trading dollars for pennies as you watch the value of your investments plummet.

Strongly consider devoting a portion of your portfolio to overseas investments.
