2. Stock market overview and market movers

U.S. stock futures are all moving up, and European markets are mostly positive in early trading. Asian markets ended the day with gains.

Shares in Samsung rallied by 2% Monday after the smartphone maker launched a replacement program in its home market of South Korea for its Galaxy Note 7 devices.

3. Oil is going up

Crude oil futures are rising by about 1.5% to trade around $43.50 per barrel based on hopes that OPEC could soon agree to freeze production levels, along with Russia.

OPEC and other producers will hold an informal meeting in Algeria next week to discuss the possibility of capping oil production in a bid to boost prices.
