JPMorgan Chase and Citigroup reported better-than-expected fourth-quarter earnings on Tuesday, while Wells Fargo missed.

What happened: JPMorgan's and Citigroup's stock both gained more than 1% while Wells Fargo dropped by over 5%.

By the numbers: JPMorgan, the largest U.S. bank by assets, reported earnings of $2.57 a share and revenue rose 9% to $29.2 billion. Citi reported EPS of $1.90 and revenue, net of interest expense, rose about 7% to $18.38 billion — all of which beat analysts' expectations.

  • JPMorgan's big numbers were driven by an 86% surge in bond trading revenue, year over year.
  • Citi saw trading revenue rise nearly 31%, with a 49% jump in fixed-income trading, though equities trading fell 23% due to weak performance in derivatives.

On the other side: Wells Fargo saw total revenue decline more than 5% to $19.9 billion. Net income took an even bigger hit, falling by more than half to $2.9 billion, down $0.60 per share.

President Trump signed an executive order on Monday that would impose sanctions on any person or entity that contributes to the supply, sale, or transfer of conventional arms to or from Iran or is engaged in providing training and financial support related to those weapons.

Why it matters: The executive order is the first step by the Trump administration to put teeth into its claim that international sanctions on Iran were restored over the weekend, one month after the U.S. initiated the "snapback" process under a United Nations Security Council resolution.

CDC says it mistakenly published guidance about COVID-19 spreading through air

The CDC has removed new guidance that acknowledged airborne transmission of the coronavirus, posting in a note on its website that the guidance was only a draft and had been published in error.

Why it matters: The initial update — which was little noticed until a CNN story was published Sunday — had come months after scientists pushed for the agency to acknowledge the disease was transmissible through the air. The CDC previously said that close person-to-person contact was the bigger concern, and the language has been changed back to erase the warning about airborne transmission.
