The euro and U.S. stocks dropped on Tuesday (November 27) as concern over the threat to the world economy posed by the U.S. "fiscal cliff" offset optimism from a deal to ease Greece's debt burden, though European and Asian stocks gained on initial investor optimism.

The Dow Jones industrial average ended down 89.24 points, or 0.69 percent, at 12,878.13. The Standard & Poor's 500 Index was down 7.35 points, or 0.52 percent, at 1,398.94. The Nasdaq Composite Index was down 8.99 points, or 0.30 percent, at 2,967.79.
