The S&P 500 pushed back over 2,000 in opening trade Tuesday, after closing short of the mark that it touched for the first time Monday.

Solid US economic data and some supporting company news, including positive earnings from electronics retailer Best Buy and a confirmation of the Burger King takeover of Canada's Tim Hortons fast-food chain, helped sustain fresh buying.

Five minutes into trade, the blue-chip Dow Jones Industrial Average rose 37.16 points (0.22 percent) to 17,114.03.

The broad-market S&P 500 was up 3.76 (0.19 percent) at 2,001.68, while the tech-rich Nasdaq Composite added 7.69 (0.17 percent) to 4,565.03.
