Earnings Not Telling The Story For Power Solutions, Ltd. (TSE:4450) After Shares Rise 46%

Power Solutions, Ltd. (TSE:4450) shares have continued their recent momentum with a 46% gain in the last month alone. Looking further back, the 22% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

Following the firm bounce in price, Power Solutions may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 17.3x, since almost half of all companies in Japan have P/E ratios under 13x 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.

For example, consider that Power Solutions' financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Power Solutions would need to produce impressive growth 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 31%. The last three years don't look nice either as the company has shrunk EPS by 14% in aggregate. 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 Power Solutions' 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 Final Word

Power Solutions' P/E is getting right up there since its shares have risen strongly. 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 Power Solutions currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. 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.
