Today, we can blame the market almost entirely on OIL and THE DOLLAR. Oil rose to a dime within $120.00 today before selling off and the dollar is becoming the PESO with the reading having hot $1.60 per EURO. Interestingly enough, the oil services stocks are not performing well in earnings season despite record prices. More importantly, today's stock market shows that the market is still in a state of flux, and it may have become a stock picker's market. Until this finally doesn't work, the trade is to buy when you feel worried and sell when you are feeling good. Below are today's unofficial market index closing levels:

• DJIA 12,720.31 (-104.71; -0.82%)
