Subdued Growth No Barrier To Sinostar Cable Co., Ltd (SZSE:300933) With Shares Advancing 36%

Those holding Sinostar Cable Co., Ltd (SZSE:300933) shares would be relieved that the share price has rebounded 36% 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 11% in the last twelve months.

Since its price has surged higher, Sinostar Cable may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 51x, since almost half of all companies in China have P/E ratios under 29x and even P/E's lower than 18x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

For instance, Sinostar Cable's receding earnings in recent times would have to be some food for thought. 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.

Does Growth Match The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Sinostar Cable'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 25%. This means it has also seen a slide in earnings over the longer-term as EPS is down 40% 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 41% shows it's an unpleasant look.

In light of this, it's alarming that Sinostar Cable'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.

What We Can Learn From Sinostar Cable's P/E?

Shares in Sinostar Cable have built up some good momentum lately, which has really inflated its P/E. 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.

We've established that Sinostar Cable currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
