The Dow Jones Industrial Average (INDEX: ^DJI) is falling for the third day in a row as the Greek debt deal looks to be delayed. At 1:30 p.m. EST, the Dow was down 70 points to 12,590.60.

The Dow is 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.

Top decliners

  1. Bank of America (NYSE: BAC) is today’s top loser so far, down 3.1% to $7.06 on the Greek debt news and a downgrade by Goldman Sachs from buy to neutral. Fool analyst Sean Williams has written about what you need to know about the Greek debt talks.
  2. American Express (NYSE: AXP) is second behind Bank of America, down 1.84% to $48.93. The company is also being pushed down by fears over the Greek debt talks. American Express posted positive earnings two weeks ago; competitor and fellow Dow component MasterCard reports earnings on Thursday.
  3. Chevron (NYSE: CVX) is third, down 1.76% to $102.13. The company is falling with the broader market and oil prices, which are now just less than $100 per barrel. Chevron reported poor earnings on Friday; ExxonMobil reports earnings tomorrow.
