New York, Oct 28 (DPA) Most US stocks fell Tuesday as consumer confidence dropped for the second straight month.

The private Conference Board’s index stood at 47.7 in October, down 5.7 points from the previous month. Rising unemployment played “a major role in this grimmer assessment”, said Lynn Franco, director of the Conference Board’s research centre.

International Business Machines Corp helped push markets higher after its board agreed to buy back $5 billion in stock.
