What Shenzhen Sine Electric Co.,Ltd.'s (SHSE:688395) 37% Share Price Gain Is Not Telling You

Shenzhen Sine Electric Co.,Ltd. (SHSE:688395) shares have had a really impressive month, gaining 37% after a shaky period beforehand. Looking back a bit further, it's encouraging to see the stock is up 49% in the last year.

Since its price has surged higher, given close to half the companies in China have price-to-earnings ratios (or "P/E's") below 38x, you may consider Shenzhen Sine ElectricLtd as a stock to avoid entirely with its 58.5x P/E ratio. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

As an illustration, earnings have deteriorated at Shenzhen Sine ElectricLtd 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.

Is There Enough Growth For Shenzhen Sine ElectricLtd?

Shenzhen Sine ElectricLtd's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered a frustrating 27% decrease to the company's bottom line. This means it has also seen a slide in earnings over the longer-term as EPS is down 53% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 37% shows it's an unpleasant look.

In light of this, it's alarming that Shenzhen Sine ElectricLtd'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

Shenzhen Sine ElectricLtd's P/E is flying high just like its stock has during the last month. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Shenzhen Sine ElectricLtd 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.
