NEW YORK (AP) — Investors will be watching to see if the stock market can sustain its rally a day after the Dow Jones industrial average closed at its highest level in 2 ½ years.

The Dow closed above 12,000 on Tuesday for the first time since June 2008. Another major market index, the Standard & Poor’s 500, closed above 1,300 for the first time since August 2008. A strong manufacturing report and positive earnings from companies such as UPS and Pfizer drove stocks higher.

Another round of earnings will likely sway stocks Wednesday. AOL, Whirlpool and Mattel are all releasing their results.

Ahead of the opening bell, Dow futures are up 6, or 0.1 percent, at 11,978. S&P 500 index future are flat at 1,303. Nasdaq 100 index futures are down 1 at 2,322.
