European stocks rose while Asian shares finished Thursday's session mixed.

2. -- The proposed Anthem  (ANTM - Get Report)  merger with Cigna  (CI - Get Report)  has been blocked by a federal judge as being anticompetitive.

The $54 billion deal has been in the works since July 2015, and the court ruling by U.S. District Judge Amy Berman Jackson in Washington will cost Anthem a $1.85 billion breakup fee unless Anthem can show that Cigna breached the merger agreement.

With the Anthem-Cigna deal now history, it's likely that Cigna will go shopping for other deals. In a conference call with investors earlier this month, CEO David Cordani said that if the megadeal ran into a road block his company would look to put its $14 billion of cash to work.
Cigna shares fell 1% in premarket trading. There was no premarket action in Anthem.

Tesla said the "brief, planned" pause would allow the company to add capacity to the existing paint shop to prepare it for the Model 3, and other general maintenance. 

"This will allow Tesla to begin Model 3 production later this year as planned and enable us to start the ramp towards 500,000 vehicles annually in 2018," a Tesla spokesman told Reuters.

Sources also told Reuters that Tesla planned to begin test-building the Model 3 on Feb. 20.

The stock rose 4.4% in premarket trading.
