Norwegian Cruise Line Holdings’ share price rocketed 19% in afternoon trading as investors ignored a deeper-than-expected quarterly loss to focus on a bullish outlook for the year ahead.

The jump added about $1.3bn in market capitalisation in a single day, based on 425m of its New York-listed shares outstanding.

The cruise shipping giant, one of the three industry titans headquartered in Miami, reported a $106m net loss for the fourth quarter of last year, which was an improvement on the $482m in red ink in the same period of 2022.
