Yes, that's a good news for investors who involved in Carnival (NYSE: CCL) stock as well as other cruise company stocks.

The CDC said Wednesday in a letter to the cruise industry that cruise operators could begin passenger voyages from the U.S. in mid-July. The CDC said that if a ship attests that 98% of its crew and 95% of its passengers are fully vaccinated that the ship may skip simulated voyages and move directly to open water sailing.

Although cruise operators still need to meet the CDC's certain requirements before sailing, the CDC will review and respond to applications for simulated voyages within 5 days, a review previously at least 60 days. But anyway, that's a good news for cruises, which means that the U.S. cruise ships will soon sail to the sea.

The U.S. cruise operators have been suspended for longer than one year due to the COVID-19 pandemic, which has cost these companies billions of dollars. Despite the CDC now gave a specific timeline for cruises, it's still remains uncertainty. Investors need to wait until July to make better trading decisions on the stock.
