The Federal Open Market Committee (FOMC)'s decision is due at 2 p.m. ET. No change in interest rates is expected but the wording of the FOMC's statement may hint at the possible timing of its next rate hike.
"In another era, there would be massive pressure on the FOMC to raise rates but no-one expects anything from today's meeting. Still, some acknowledgement of the improved economic backdrop is likely in the statement and the market will go on slowly raising the odds of a 2016 rate hike," Kit Juckes, strategist at Societe Generale, said in a note on Wednesday.
Dow-listed stocks posting second-quarter results on Wednesday include Boeing and Coca-Cola. There will also be numbers from Comcast, CNBC's parent company and State Street, among others. Facebook will post its results after the close of Wall Street trade.
Boeing posted a smaller-than-expected loss for the second quarter and cut its full-year forecast, due to previously announced charges from the 787, 747 and KC-46 tanker aircraft programs. Revenue beat estimates, and while Boeing cut its full-year forecast to account for those charges, its forecast is above Street estimates. The quarterly earnings loss was the first in nearly seven years, Reuters said.
Coca-Cola reported earnings that beat on revenue that missed. The beverage maker said international headwinds were more severe than anticipated, and that the macroeconomic environment worsened in the quarter. However, the company did see a 3 percent rise in organic revenue, thanks to better pricing.
Comcast, the NBCUniversal and CNBC parent posted earnings that beat on both the top and bottom line, and reported a 3 percent increase in revenue per cable customer over a year ago. The firm also saw good results for its internet and video businesses.
