A report showed that US orders for durable goods posted the largest gain on record in July, jumping 22.6 percent. Separately, consumer confidence strengthened to the highest level in nearly seven years in August as the Conference Board's index of consumer attitudes climbed to 92.4 from a downwardly revised 90.3 the prior month.
"Consumer confidence increased for the fourth consecutive month as improving business conditions and robust job growth helped boost consumers' spirits," Lynn Franco, director of economic indicators at the Conference Board, said in a statement.
"Consumers were marginally less optimistic about the short-term outlook compared to July, primarily due to concerns about their earnings," according to Franco. "Overall, however, they remain quite positive about the short-term outlooks for the economy and labour market."
