Those holding Yantai Ishikawa Sealing Technology Co., Ltd. (SZSE:301020) shares would be relieved that the share price has rebounded 26% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 17% over that time.

Since its price has surged higher, Yantai Ishikawa Sealing Technology may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 36.9x, since almost half of all companies in China have P/E ratios under 27x and even P/E's lower than 17x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

The earnings growth achieved at Yantai Ishikawa Sealing Technology over the last year would be more than acceptable for most companies. One possibility is that the P/E is high because investors think this respectable earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

Is There Enough Growth For Yantai Ishikawa Sealing Technology?

There's an inherent assumption that a company should outperform the market for P/E ratios like Yantai Ishikawa Sealing Technology's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 19% gain to the company's bottom line. However, this wasn't enough as the latest three year period has seen a very unpleasant 53% drop in EPS in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

In contrast to the company, the rest of the market is expected to grow by 36% 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 Yantai Ishikawa Sealing Technology'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 Bottom Line On Yantai Ishikawa Sealing Technology's P/E

Yantai Ishikawa Sealing Technology's P/E is getting right up there since its shares have risen strongly. 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.

Our examination of Yantai Ishikawa Sealing Technology 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.
