Could this be the start of some trouble ahead?

Because many of big investment banks are also involved in commodities it could be we will see drop in oil price as well.

Normally these guys don't act alone and because major banks and houses are to some extend connected with each other investors will be cautious to see how far GS has infected others.

In fact a correction after the big steady rise since the collpase shouldn't be a bad thing.
