Shell reports $5.6 billion in Q3 profits

• Shell said higher oil, gas and LNG prices, as well as money from its gas trading unit, were behind the rise.
• But those gains were partly offset by factors including lower margins in refining and "adverse currency exchange effects."

Where it stands: The company used the report to say it's rewarding investors by increasing its share buybacks to $2.5 billion between now and late January.

• That's up from $2 billion in the prior phase of the program that envisions $25 billion in buybacks by the end of 2020.

What's next: Exxon and Chevron, the largest U.S.-based majors, will report their Q3 results on Friday morning.
