With a price-to-earnings (or "P/E") ratio of 36.4x China Literature Limited (HKG:772) may be sending very bearish signals at the moment, given that almost half of all companies in Hong Kong have P/E ratios under 9x and even P/E's lower than 5x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

With earnings growth that's superior to most other companies of late, China Literature has been doing relatively well. The P/E is probably high because investors think this strong earnings performance will continue. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

In order to justify its P/E ratio, China Literature would need to produce outstanding growth well in excess of the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 33% last year. 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.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 20% each year over the next three years. With the market only predicted to deliver 16% per year, the company is positioned for a stronger earnings result.

With this information, we can see why China Literature 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.

The Final Word

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that China Literature maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. It's hard to see the share price falling strongly in the near future under these circumstances.
