Sanofi (SNY) – The drug maker’s shares slipped 3.7% in the premarket after the FDA put a trial related to its erectile dysfunction drug Cialis on hold.

Nio (NIO) – Nio shares jumped 5.1% in the premarket after Morgan Stanley added the China-based electric vehicle maker’s stock to its “tactical idea” list.

Zoom Video Communications (ZM) – The videoconferencing company’s stock received a double upgrade at Daiwa Securities, which raised its rating to “outperform” from “underperform”.

American Eagle Outfitters (AEO) – The apparel retailer’s stock slid another 5.7% in the premarket after a post-earnings tumble of 6.6% Friday.
