Dow Falls 204 Points, Interrupting 2012 Rally

Stocks have suffered their biggest losses in more than three months. The Dow Jones industrial average is finishing the day down 204 points.

The sell-off in the U.S. on Tuesday followed stock declines in Europe. Greece faces a Thursday deadline to get private investors to agree to the terms of its bailout. And some investors worry that the rally in stocks this year has been too much, too fast.

The Dow finished at 12,759. The Standard & Poor's 500 index fell 21 points to finish at 1,343. The Nasdaq composite index lost 40 points to close at 2,910.

All 10 industry groups in the S&P 500 declined. Declining stocks outnumbered advancers 10-to-1. Volume was about average at 4.15 billion shares.
