The Dow opened down after German Chancellor Angela Merkel declined to discuss Greece this morning at a European summit in Brussels. The reason given was that the governing bodies that oversee the Greek bailout packages are still in talks with Greece, banks, and other bondholders. Investors believe a second debt bailout is needed to keep Greece from defaulting.

The rest of the day, though, was a slow climb for the Dow, and it nearly ended up.
