Here's a deeper look at stocks on the move Tuesday:

Twitter

The discussions have been taking place since the beginning of the year, Re/Code reported, citing multiple sources with knowledge of the matter. But the sources said talks between Twitter and Flipboard are currently stalled.

AstraZeneca

Shares of AstraZeneca PLC (ADR) (NYSE:AZN) dipped more than 2 percent Tuesday after the biopharmaceutical company’s experimental psoriasis drug was linked to suicide fears. Amgen Inc. announced Friday it was ending its partnership with AstraZeneca to develop Brodalumab, a treatment for psoriasis.

“The decision was based on events of suicidal ideation and behavior in the brodalumab program, which Amgen believes likely would necessitate restrictive labeling,” Amgen said in a statement Friday.
