Earnings season heats up this week, with more than 100 of America's biggest companies set to announce financial results. Here are the most important companies to watch

  1. Aetna and Anthem: Two of the nation's largest health insurers release earnings Tuesday and Wednesday morning, respectively. Both companies have lost money due to participation in Obamacare exchanges, and both are attempting to consolidate with rivals as a result of the law. Look for clues as to how the industry will deal with antitrust oversight and Obamacare repeal.
  2. Facebook: is being cautious projecting future growth of ad sales on its flagship product, but we'll begin to learn Wednesday evening how profitably it can leverage subsidiaries like Instagram, WhatsApp, and Oculus.
  3. Amazon: the online retailer's "echo" products were the runaway hit of the holiday season. On Thursday, Amazon's reported revenues will tell us just how popular they were.
  4. Drug companies: Several of the nation's largest drug makers will announce earnings this week, including Pfizer early Tuesday and Merck on Thursday. Look for indications on how the industry plans to combat efforts to force drug companies to negotiate prices with Medicare or other federal entities.

Over 73 million people watched the first debate on TV

More than 73.1 million people watched the first presidential debate on television on Tuesday night, according to Nielsen ratings.

Why it matters: While that's a sizable audience for any American TV program, it's down more than 13% from the record number of TV viewers who tuned in for the first debate of the 2016 election. The chaotic nature of the debate and the overall uncertainty around this year's election may have pushed some viewers away.

Senate passes bill funding government through December

The Senate on Tuesday passed legislation to fund the federal government through Dec. 11, by a vote of 84-10.

Where it stands: The legislation will avert a government shutdown before funding expires Wednesday night and before the Nov. 3 election. The House passed the same measure last week by a vote of 359-57 after House Democrats and the Trump administration agreed on the resolution.

  • Both sides agreed early in negotiations that the bill should be a "clean" continuing resolution — meaning each party would only make small changes to existing funding levels so the measure would pass through both chambers quickly, Axios' Alayna Treene reported last week. The bill now goes to President Trump for his signature.
