1. Travel ban fallout: Global markets are trading lower after a weekend of confusion and protests over an executive order issued by President Trump that bans travel from seven Muslim-majority nations.
The dollar weakened and U.S. stock futures were trading lower ahead of the open.
"The U.S. travel clampdown dominated the weekend's news and resulted in the dollar being marked down by about 0.5% at the start of Asian trading," noted Kit Juckes, a strategist at Societe Generale (SCGLF).
Travel stocks were also under pressure early Monday. International Airlines Group, the owner of British Airways and Iberia, was down 1.7%, while Air France-KLM (AFLYY)shed 2%. Hotel operator Accor (ACCYY) dropped 1.6%.
The controversial order has been publicly criticized by top corporate leaders -- especially those from the tech industry.
Starbucks (SBUX) said it would hire 10,000 refugees over five years in response to the ban. General Electric (GE) and JPMorgan Chase (JPM) have also expressed concerns about how the order will affect their employees.
2. Volkswagen is back: Volkswagen (VLKAF) has toppled Toyota (TM) as the world's top-selling automaker, despite the massive fallout from its emission rigging scandal.
Toyota said Monday it sold 10.2 million vehicles worldwide in 2016, falling short of the 10.3 million vehicles Volkswagen delivered.
