The market tried to hit a new two-plus-year high again today. Anything cautious for the markets is being discounted and valuation concerns are out the door. It seems the bulls are in charge -- regardless of what comes down the pipe in the Middle East, Japan, the PIIGS and elsewhere. Even a goal of only aiming to cut foreign energy dependence by one-third did not rattle markets. The TARP even made money. Maybe we can just convince Bernanke to go ahead and raise rates to get the pain over with, once and for all.

Here were today's unofficial closing bell levels:

Dow Jones: 12,350.61 +71.60 (0.58%)

S&P500: 1,328.26 +8.82 (0.67%)

Nasdaq: 2,776,78 +19.90 (0.72%)
