I too am a share holder and am tired of all the bad press about the Millennium Class ships having to cancel cruises. I am not sure what the litigation will bring, but I am not sure if replacement pods are the answer. (Carnival is having similar problems on azipod ships) RCL stock has tumbled the last few days too. I am not sure its related to the Summit problem, but it cannot help.
The more direct cause of the recent fluctuation is the reverse fluctuation in the price of fuel. The pod problem is not news at this point so it was priced into the stock long ago.
As an investor, I look at the drop as a buying opportunity. The market put the stock on sale. The market usually overreacts to phenomena like the fluctuation in the price of oil, creating a temporary discount in the price of the shares of stocks that depend upon oil. It will soon correct for the overraaction.
