1) The big items from day 2 of CES

The CEOs of Qualcomm, Under Armor, and Intel are among the speakers scheduled for Friday. The biggest buzz so far has been about Amazon's voice-controlled assistant, Alexa, and Nvidia, the chip maker.

2) Bitcoin's price roller coaster continues

As of the early hours on Friday, Bitcoin continues to fall. The cryptocurrency hit $1153.02 on Wednesday, before crashing yesterday. Some speculate that it was caused by Chinese investors attempting to move their money out of the country.

3) Samsung's surprising Q4 profit guidance

The Food and Drug Administration on Saturday issued an emergency use authorization for Johnson & Johnson's one-shot coronavirus vaccine.

Why it matters: The authorization of a third coronavirus vaccine in the U.S. will help speed up the vaccine rollout across the country, especially since the J&J shot only requires one dose as opposed to Moderna and Pfizer-BioNTech's two-shot vaccines.
