Still, the S&P 500 and the Nasdaq Composite both finished up 0.1%, while the Dow Jones Industrial Average rose 0.3%. The recent gains have many observers feeling upbeat, with some even positing that the S&P 500 has finally resumed its uptrend. Maybe. But even some of the bulls acknowledge that it could be time for a pause. Todd Market Forecast's Stephen Todd notes thatbreadth was negative today, even though the market finished higher. "Frequently this is a precursor of a correction," he writes. "We've had a good run and a bit of weakness wouldn't be surprising." Still, there are reasons for optimism...five of them actually.

"Five circuit breakers turned positive & point to further upside," Parker writes. We can only hope.
