U.S. stock index futures pointed to a higher open Tuesday, looking to add to gains from the previous session, with the Institute for Supply Management (ISM) manufacturing survey for March in focus.
Investors will look to data on the manufacturing sector for an indication of the economy's health after lackluster data earlier in the year was attributed to a harsh winter. The final Markit manufacturing PMI for March is due at 9:45 am ET and the Institute for Supply Management's manufacturing reading for March is due at 10 am ET.
ISM is expected to show a reading of 54 versus the prior 53.2. A reading above 50 indicates expansion. The prior Markit reading came in at 55.5.
In addition, construction spending data for February is due at 10 am ET. Expectations call for a flat reading versus the prior gain of 0.1 percent.
Also in the corporate space, Apollo Group will publish quarterly numbers early during the day.
