What Zhejiang Yilida Ventilator Co.,Ltd.'s (SZSE:002686) 30% Share Price Gain Is Not Telling You

Those holding Zhejiang Yilida Ventilator Co.,Ltd. (SZSE:002686) shares would be relieved that the share price has rebounded 30% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 29% in the last twelve months.

Since its price has surged higher, given close to half the companies in China have price-to-earnings ratios (or "P/E's") below 29x, you may consider Zhejiang Yilida VentilatorLtd as a stock to avoid entirely with its 72.6x 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 Zhejiang Yilida VentilatorLtd 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.

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

The only time you'd be truly comfortable seeing a P/E as steep as Zhejiang Yilida VentilatorLtd's is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 29% decrease to the company's bottom line. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's noticeably less attractive on an annualised basis.

In light of this, it's alarming that Zhejiang Yilida VentilatorLtd's P/E sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Final Word

Zhejiang Yilida VentilatorLtd's P/E is flying high just like its stock has during the last month. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Zhejiang Yilida VentilatorLtd revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Zhejiang Yilida VentilatorLtd, and understanding should be part of your investment process.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
