MUST READ THIS LINK!
* Goldman Sachs HFT accounts for a ****load of market liquidity across pretty much every single instrument class
* Goldman Sachs prop desk was really terrible at trading during 07/08
* GS is probably the largest futures trader in the world
I really recommend everyone read this article. As a trader it makes me think "great, the market will keep moving and I can keep trading as long as GS is around" as an investor it makes me think "this is bull****, the whole thing is manipulated, why would I leave any money invested in anything when over half the market is just GS anyway".
