President Trump will announce his pick to lead the Federal Reserve this afternoon. Janet Yellen's term ends in February. 

Meanwhile, Facebook reported its earnings yesterday and they blew past expectations. The site now has more than 2 billion active users, an increase of 16 percent from last year. 

Shares initially popped, but are now falling because CEO Mark Zuckerberg says the company will spend so much money on security that it will "significantly impact" profits. 

Lastly, LinkedIn analyzed data from its site to figure out the top 50 startups that job seekers want to work for. 

WeWork, AirBNB, Lyft and Slack are in the top five, and at No. 1 is Uber, despite all the negative headlines about its company culture.
