Cruise stocks — Carnival popped 8.81%, Norwegian Cruise Line gained 7.55% and Royal Caribbean added 1.68%, extending gains from Tuesday after Carnival reported a smaller-than-expected loss for its second quarter and issued strong guidance.

ZoomInfo — The software stock rose 6.09% after Needham initiated coverage of ZoomInfo with a buy rating. Needham said in a note to clients that ZoomInfo has "best in class unit economics."
