Well this is commodity prices rather than stocks. China has slowed dramatically and they have been the biggest buyer of commodities. And fracking has killed the price of oil by making natural gas available at a much cheaper price.
Has it been NG fracking or the saudis ramping up production to kill fracking?
Commodity prices are like a thermometer. They reveal weakness just as that instrument can detect a problem with ones health before it manifests itself. It puts the lie to all of Obama’s self serving statements about how great the economy is.
