Sunshine Global Circuits Co.,Ltd.'s (SZSE:300739) 29% Share Price Surge Not Quite Adding Up

Sunshine Global Circuits Co.,Ltd. (SZSE:300739) shares have had a really impressive month, gaining 29% after a shaky period beforehand. Unfortunately, despite the strong performance over the last month, the full year gain of 6.0% isn't as attractive.

After such a large jump in price, Sunshine Global CircuitsLtd may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 40.6x, since almost half of all companies in China have P/E ratios under 28x 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.

For example, consider that Sunshine Global CircuitsLtd's financial performance has been poor lately as its earnings have been in decline. 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.

Is There Enough Growth For Sunshine Global CircuitsLtd?

There's an inherent assumption that a company should outperform the market for P/E ratios like Sunshine Global CircuitsLtd's to be considered reasonable.

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 35%. This means it has also seen a slide in earnings over the longer-term as EPS is down 24% 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.

Comparing that to the market, which is predicted to deliver 41% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Sunshine Global CircuitsLtd is trading at a P/E higher than the market. 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 Bottom Line On Sunshine Global CircuitsLtd's P/E

Sunshine Global CircuitsLtd'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 Sunshine Global CircuitsLtd 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.
