If you follow "Elliot Wave Theory" we are entering a Kondratieff Winter phase.
There is evidence (unproveable at this time) that there is some "offshore" govt intervention and manipulation. Google up "Plunge Protection" and read what you read and THEN decide if the market your "investing in" is not a rigged game.
I got out 2 years ago, it may or may not be the case, but Iam not willing to take that type of chance with my resources when thee is some feasible evidence that this is going on. I like to error on the side of conservatism when the results make the difference of whether or not I have to hang up the surfboards and go back to work.
