Stocks have been on a one-way train all month long. Now, as we approach Groundhog Day, the market appears to be having its own version of it as the Dow faces 14,000 and the S&P 500 struggles at 1500.

Or will they bravely march forward into the clear blue skies to challenge the all-time highs from 2007?
