U.S. markets rebounded on Tuesday after Monday's losses on better than expected Q2 results from big names and positive economic data. In Ukraine, pro-Russia rebel leaders handed over the black boxes from the downed Malaysian Airlines plane to Malaysian experts in Ukraine. A slew of earnings and the latest government data on inflation also helped stocks move higher. The consumer price index increased 0.3%, matching estimates. Investors will be watching Netflix (NFLX) and Chipotle (CMG) in Tuesday's trading after the two companies reported earnings after the bell Monday. Verizon (VZ) said second quarter earnings nearly doubled, after its recent acquisition of Verizon wireless. McDonald's (MCD) shares are lower after reporting earnings that missed estimates.
