When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 18x, you may consider Royal Caribbean Cruises Ltd. (NYSE:RCL) as a stock to potentially avoid with its 24.7x P/E ratio. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.
Recent times have been advantageous for Royal Caribbean Cruises as its earnings have been rising faster than most other companies. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?
There's an inherent assumption that a company should outperform the market for P/E ratios like Royal Caribbean Cruises' to be considered reasonable.
Retrospectively, the last year delivered an exceptional 66% gain to the company's bottom line. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.
Looking ahead now, EPS is anticipated to climb by 21% per annum during the coming three years according to the analysts following the company. Meanwhile, the rest of the market is forecast to only expand by 10% per year, which is noticeably less attractive.
With this information, we can see why Royal Caribbean Cruises is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.
