Wowow Inc. (TSE:4839) Stock Rockets 27% As Investors Are Less Pessimistic Than Expected

The Wowow Inc. (TSE:4839) share price has done very well over the last month, posting an excellent gain of 27%. Taking a wider view, although not as strong as the last month, the full year gain of 14% is also fairly reasonable.

Following the firm bounce in price, given close to half the companies in Japan have price-to-earnings ratios (or "P/E's") below 13x, you may consider Wowow as a stock to avoid entirely with its 56.2x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

As an illustration, earnings have deteriorated at Wowow 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

Does Growth Match The High P/E?

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

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 42%. This means it has also seen a slide in earnings over the longer-term as EPS is down 85% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 8.3% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's alarming that Wowow's P/E sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

The strong share price surge has got Wowow's P/E rushing to great heights as well. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

Our examination of Wowow 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.

Don't forget that there may be other risks. For instance, we've identified 5 warning signs for Wowow (1 makes us a bit uncomfortable) you should be aware of.
