A slew of economic statistics pointed to an upswing in psychology among Americans, an important factor in an economy reliant for two-thirds of its activity on consumer spending. The Conference Board, the New York-based research organisation, said that its consumer confidence index showed its biggest gain since 1998 in the latest survey period. The Board said that the index rose to 93.7 from 84.9 the previous month in its first gain since June. Separately, Washington reported that weekly claims for unemployment benefits came it at 392,000, down from the peak of 535,000 in the weeks following the 11 September terror attacks. Demand for housing remained strong, while durable goods orders fell back 4.8% in November after October's 12.5% surge.
