Currencies and currency markets play a crucial role in a portfolio, especially over the long term. By taking advantage of the long term economic global trends one can really lower his investing risk and increase his rewards.
I discuss what gives strength to a currency, long term currency outlook, how inflation affects currencies, and where are the current investment opportunities to buy currency investments on the cheap for proper international portfolio diversification.
I also discuss forex but it is a bit complicated.
Emerging markets are the key from every aspect.
