There's No Escaping Sanken Electric Co., Ltd.'s (TSE:6707) Muted Earnings Despite A 35% Share Price Rise

Sanken Electric Co., Ltd. (TSE:6707) shares have had a really impressive month, gaining 35% after a shaky period beforehand. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

Although its price has surged higher, Sanken Electric's price-to-earnings (or "P/E") ratio of 4.7x might still make it look like a strong buy right now compared to the market in Japan, where around half of the companies have P/E ratios above 14x and even P/E's above 21x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.

Recent times have been advantageous for Sanken Electric as its earnings have been rising faster than most other companies. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

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

There's an inherent assumption that a company should far underperform the market for P/E ratios like Sanken Electric's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 410% gain to the company's bottom line. Pleasingly, EPS has also lifted 4,992% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing earnings over that time.

Turning to the outlook, the next three years should bring diminished returns, with earnings decreasing 34% each year as estimated by the four analysts watching the company. That's not great when the rest of the market is expected to grow by 9.2% per annum.

With this information, we are not surprised that Sanken Electric is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Final Word

Even after such a strong price move, Sanken Electric's P/E still trails the rest of the market significantly. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

As we suspected, our examination of Sanken Electric's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.

It is also worth noting that we have found 3 warning signs for Sanken Electric (2 can't be ignored!) that you need to take into consideration.
