Ultimately rising interest rates mean to the market more then falling oil. So if today higher rates trend was confirmed market may dump despite the fall in oil.
How about this scenario : Criminals dropped the oil first to scare bond and stock shorts and then started unloading bonds. Pretty tricky day in the markets.
One day does not make a trend, and I fear we are wasting a lot of munition keeping up above 2000. Just took of PXR here at $17.03, a bad loss of $.70. This one is dead for a while.
