Frontier International Inc.'s (TSE:7050) 27% Share Price Surge Not Quite Adding Up

Frontier International Inc. (TSE:7050) shares have continued their recent momentum with a 27% gain in the last month alone. Taking a wider view, although not as strong as the last month, the full year gain of 22% is also fairly reasonable.

After such a large jump in price, Frontier International may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 16.3x, since almost half of all companies in Japan have P/E ratios under 12x and even P/E's lower than 9x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

We've found 21 US stocks that are forecast to pay a dividend yield of over 6% next year. See the full list for free.

As an illustration, earnings have deteriorated at Frontier International over the last year, which is not ideal at all. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. 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 Frontier International's to be considered reasonable.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 27%. The last three years don't look nice either as the company has shrunk EPS by 62% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 10% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's alarming that Frontier International's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Final Word

The large bounce in Frontier International's shares has lifted the company's P/E to a fairly high level. 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.

Our examination of Frontier International revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
