Take a look at some of Tuesday's after hours buzz:
Kraft Foods edged higher in after-hours trade on news that the packaged foods company increased quarterly dividend by about 5 percent.
Twitter traded flat in extended-hours on news that the social media firm had sued the U.S. Department of Justice and the FBI for the right to reveal more information on U.S.government surveillance and requests for information from federal agencies.
GT Advanced Technologies gained nearly 5 percent in after-hours trade, building on Tuesday's recovery after sliding on Monday's report that Apple's sapphire substrate producer had filed for bankruptcy. Competitor Rubicon Technology fell more than 1 percent in extended-hours trade.
Wal-Mart gained slightly in after-hours trade after the superstore announced it plans to eliminate health insurance coverage for most of its part-time U.S. employees in an effort to control rising health care costs. The company is the nation's largest private employer.
