U.S. stock index futures pushed higher on Wednesday ahead of more housing data and several fourth-quarter earnings updates.
Investors will be looking ahead to the January reading on new home sales, due at 10:00 am ET, which is expected to have dropped slightly from the prior month.
"The data focus remains on the housing market with January's new home sales figures due. The expectation is for a further drop of about 3 percent month-on-month, following a decline of 7 percent in December, with the full extent of inclement weather in driving the fall unclear," said Daiwa Capital Markets' Chris Scicluna in a morning research note.
Among earnings, Target gained after the retailer edged past Wall Street expectations. The company said the December data breach shaved two cents a share off its earnings and impacted sales as well, though CEO Gregg Steinhafel said sales trends have improved in recent weeks.
In addition, crude oil inventories for last week will be published at 10:30 a.m.
