And as for manipulation, that's what happens when you're not smart, skilled or talented or of good standing in the community. If you can't make it honestly through locating, researching and analysing good investments in the world you have to cheat or steal to get ahead.
It's not smart.... manipulating a share price to make money isn't a talent or skill or anything to be proud of in life with regard your professional accomplishments and career. The weak and poor of mind do that just like in most things in life where people cheat to get ahead.
I have every faith in Darwinian theory in that these underhanded and weak individuals and organisations manipulating the share price through use of the capital of their employers (not their own) will be moved aside by the proper and rightfully smart and skilled fund managers of the world.
