The (weekly) chart below is probably self explanatory, but as usual the next bar should always be watched to help confirm what happened in the previous bar. It appears that Carnival were quite unlucky to have Hurricane Irma cause a sell down, then within a week, have North Korea fire another missile (which seems to have a negative influence for the cruise industry), and cause price to fall again, even though most of the overall market used any weakness caused by North Korea as a buying opportunity.
Prior to the Hurricane, there was no overt sign of supply issues, so the end of the uptrend didn't look imminent at that time, and this doesn't appear to be an engineered supply event.
It appears it was just a bit of a double whammy of bad luck for the company, and then a knee jerk reaction by the market, as it played catch up to the events that may influence the company.
After the hurricane didn't look so serious (to the company), the price action looked like it might form a (bullish ??) shakeout.
I am not sure how serious the North Korea stuff is to the industry, volume was even higher than the hurricane volume though......
Next week's response on the daily and weekly timeframes should explain how much damage the events have caused the shareprice.
