A much better explanation of the function speculation performs in the market than I can give. BTW, Walter Williams is as libertarian an economist as you'll find:
Scapegoating Speculators by walter williams
I like WW . I concur with him about government interference .
He dealt with the Futures market in the form that it was intended ... to level out the prices of commodities for the sake of stability .
It was shown ... and I don't have the links at hand .. that when oil hit the 150 mark there was manipulation .
With in the Futures market and the physical supply .
I am not for regulating futures .. as a matter of fact that market is regulated less , in some respects than the NYSE and CBOE - options .
I was just putting out info .. food for thought .
Thanks
