US stocks took their biggest single-day tumble Tuesday since August as European officials tried to prevent Ireland’s debt trouble from escalating into another Greek-style fiasco.

“What a day, an ugly day across the board, in part the fault of the Irish here,” said Jeff Kleintop, chief market strategist at LPL Financial.

The Dow Jones Industrial Average fell 178.47 points, or 1.6 percent, to 11,023.50.

The S&P 500 declined 19.41 points, or 1.6 percent, to 1,178.34. The Nasdaq Composite Index was off 43.98 points, or 1.8 percent, to 2,469.84.
