Two big cruise ship stocks are Carnival (symbol CCL) and Royal Caribbean (symbol RCL). They’re doing ok, although off a bit from their highs, unsurprisingly.
I’d expect them to take a big hit if a couple more cruise ships get quarantined like the Diamond Princess, and especially if new cases keep popping up after the supposed original incubation period. That would indicate transmission while in quarantine, and the public might get the idea that they could get trapped on a diseased ship for a long, long time. That would tank their business and their stocks, which would lead to a buying opportunity down the road.
Holland America around Patagonia was a great cruise. No rig rats running up and down the hallway. Great captain briefings, social events, buffets the full range.
