NEW YORK - US stocks fell noticeably on Tuesday, pressured by the ongoing Ukraine crisis.

The Dow Jones Industrial Average dropped 482.57 points, or 1.42 percent, to 33,596.61. The S&P 500 fell 44.11 points, or 1.01 percent, to 4,304.76. The Nasdaq Composite Index decreased 166.55 points, or 1.23 percent, to 13,381.52.

All the 11 primary S&P 500 sectors ended in red, with consumer discretionary and energy down 3.04 percent and 1.53 percent, respectively, leading the losses.

US-listed Chinese companies traded mostly lower with nine of the top 10 stocks by weight in the S&P US Listed China 50 index ending the day on a downbeat note.

The above market reactions came as investors nervously eyed updates concerning the geopolitical tensions over Ukraine.
