This is what you need to know on Tuesday:

1. European stocks open higher Tuesday as investors return to risk markets following solid U.S. data and a modest overnight rebound for the dollar ahead of the Federal Reserve's two-day rate setting meeting.

2. Global oil prices were also extending gains after an informal meeting of OPEC members agree to eventually set caps on the output levels of Libya and Nigeria, both of which are currently exempt from the cartel's agreed production cuts, and Saudi Arabia, the world's biggest producer, said it would limit exports to its customers in August.

3. Akzo Nobel NV (AKZOY)  will hold an extraordinary shareholders meeting in September to deal with its CEO succession plans and articulate the reasons behind its rejection of a $30 billion approach from PPG Industries (PPG) .

4. A hefty $2.74 billion antitrust fine levied against Alphabet Inc. (GOOGL)  dented its second-quarter earnings, causing profits to slump 28% year-over-year.

5. Domino's Pizza Group plc (DPUKY)  said Tuesday that it will launch a voice-activated ordering service linked with Amazon Inc.'s (AMZN)  Echo device after the U.K.-based franchise of Domino's Pizza Inc. (DPZ)  posted solid first half earnings and said it was accelerating its rollout of new stores.
