US equity futures were treading water before the opening bell on Tuesday as investors awaited delayed Q3 economic data that could impact markets.

In premarket trading, Dow Jones futures, Nasdaq futures, and S&P 500 futures were all flat to slightly lower.

Trading activity was subdued ahead of a shortened trading day on Wednesday and market closure on Christmas.

Oil prices edged up slightly with West Texas Intermediate crude up 0.2% to $58.10 per barrel and Brent Crude up 0.2% to $62.12 after US President Donald Trump eased Venezuela war jitters in a speech late Monday focused on a news class of warships named after himself instead of the oil-rich South American country.

Delayed Q3 GDP numbers, scheduled to be released before the opening bell, are expected to come in at a robust 3.2% percent thanks to an increase in net exports.

October numbers on durable goods orders are also expected to be released before the bell, with forecasts showing a decrease of as much as 4.5%. The Federal Reserve's report on November industrial production is expected to show a slight increase of 0.1%.
