The largest and most active stock markets are in The United States and one would think that Africa would have few people interested in investing. After all, Africa is one of the poorest places in the world and you don’t hear many good things on the news about any African economy.
I have a page about how to buy Facebook stock (https://www.facebook.com/HowToBuyStocksOnline) and you would think that most of the interest would come from people living in America. To my amazement many inquires come from all over the world and Africa is high on the list. It seems the power of Facebook is truly global and it doesn’t matter where you live, if you have money you are probably interested in making more.
Buying Facebook stock is easy if you are a US citizen but much harder if you aren’t. Many US stock brokers require a SSN number and that you are a citizen of America. Other brokers will allow people in some countries to sign up but not in other countries.
Buying any stock on an American market will be a problem for someone who lives in Africa. The best advice is to find out whether there are any local broker companies that will allow you to trade US stocks. There may not be though, as Africa is many years behind the rest of the world in technology.
