The U.S. stock index futures pointed to a higher open Tuesday as investor sentiment turned positive amid hopes that the Federal Reserve would announce monetary easing measures this week to revive the economic growth momentum.
Futures on the Dow Jones Industrial Average were up 0.22 percent, futures on the Standard & Poor's 500 index were up 0.28 percent and those on the Nasdaq 100 index were up 0.34 percent.
Investors are expected to focus on the Bureau of Economic Analysis' trade deficit report to be released Tuesday.

On Monday, the U.S. markets fell as investors stayed watchful awaiting the Fed's announcement of stimulus measures to boost the economic growth.

The Dow Jones Industrial Average fell 0.39 percent, the S&P 500 Index was down 0.61 percent and the Nasdaq Composite Index declined 1.03 percent.
Most of the European indices were in red Tuesday as investor confidence was weighed down by increasing concerns of the debt crisis affecting the euro zone.
The "Outright Monetary Transactions" (OMT) program outlined by the European Central Bank (ECB) is primarily designed to help the larger euro zone economies, such as Spain and Italy. But the market players do have worries about other economies, especially Greece.
Investors are focusing on the meeting between Greek Prime Minister Antonis Samaras and ECB President Mario Draghi in Frankfurt Tuesday. London's FTSE 100 was down 7.58 points, Germany's DAX 30 index fell 4.30 points and France's CAC 40 dropped 5.05 points.
Most Asian markets fell Tuesday due to the fading optimism that had been initially raised by the ECB's announcement of the bond-buying plan last week.
