Yes the American stock market is a great place to put your money and the best when it comes to making some long term investments. The American stock market has a rich and great history when it comes to looking after people's money and helping it to grow year upon year.
These days, it can be hard to decide what to do with money that you intend to save or invest for the future. Yet while nothing is absolutely a sure bet, the US stock market still seems like a good choice. On the whole, it tends to be less volatile than some other markets, especially compared to the Russian or Chinese market.
The American stock market is not the "best" place to put your money, then no stock market is truly the best place to park your long-term investment funds. The best for your long-term investments funds is a managed index funds account. By investing in index funds you are assured of keeping pace with inflation and sound management will provide equity growth.
There is little confidence in the stock market unless it's money you can afford to lose. People prefer to have things like a holiday home or a boat that they can enjoy and then sell on if they need the funds. They want to see where their money is and there is a distrust of the banking industry after all the recent scandals.
