There's Reason For Concern Over Taiwan Mobile Co., Ltd.'s (TWSE:3045) Price

When close to half the companies in Taiwan have price-to-earnings ratios (or "P/E's") below 20x, you may consider Taiwan Mobile Co., Ltd. (TWSE:3045) as a stock to potentially avoid with its 23.8x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

Taiwan Mobile certainly has been doing a good job lately as it's been growing earnings more than most other companies. 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.

How Is Taiwan Mobile's Growth Trending?

Taiwan Mobile's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Retrospectively, the last year delivered an exceptional 18% gain to the company's bottom line. As a result, it also grew EPS by 22% in total over the last three years. Accordingly, shareholders would have probably been satisfied with the medium-term rates of earnings growth.

Shifting to the future, estimates from the seven analysts covering the company suggest earnings growth is heading into negative territory, declining 0.7% over the next year. Meanwhile, the broader market is forecast to expand by 25%, which paints a poor picture.

In light of this, it's alarming that Taiwan Mobile's P/E sits above the majority of other companies. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock at any price. There's a very good chance these shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the negative growth outlook.

The Bottom Line On Taiwan Mobile's P/E

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Taiwan Mobile currently trades on a much higher than expected P/E for a company whose earnings are forecast to decline. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings are highly unlikely to support such positive sentiment for long.
