Redistribution of wealth. That's what I think is going on. Power is once again moving westward. This time to China; and in a lesser extent, India. This time the power is not necessarily military. It is trade.
I'm convinced that if money were to be taken away from everyone then redistributed evenly back to everyone; those that were poor will be poor again and those that were wealthy would be wealthy again.
Now the problem with trading oil futures comes down to personal wealth and risk aversion. To trade just one contract of crude, you would need Initial Margin: $9,788 Maintenance Margin: $7,250 in your margin account. Then you may have to suffer through large draw downs even in one day. It is all leverage. Just a $0.01 (1 cent) move in oil per barrel would give you $10 plus or minus. This is not a paper gain or loss. This is removed from your account as it happens - or gained. You may want to stick with stocks or stock mutual funds.
