US stocks pushed to new record highs Tuesday, bolstered by solid US manufacturing orders and strong results from US automakers. At the closing bell, the Dow Jones Industrial Average stood at 14,659.02, up 86.17 (0.59 percent) and at a new all-time record close. The broad-based S&P 500 also reached a new record, gaining 7.84 (0.50 percent) to 1,570.01. The tech-rich Nasdaq Composite Index added 15.69 (0.48 percent) at 3,254.86.

Also Tuesday, General Motors, Ford and Chrysler reported their best US monthly sales performances since 2007. GM cited \"a strengthening economy and new products\" as factors behind the result.
