Investor Optimism Abounds Sinostar Cable Co., Ltd (SZSE:300933) But Growth Is Lacking

When close to half the companies in China have price-to-earnings ratios (or "P/E's") below 34x, you may consider Sinostar Cable Co., Ltd (SZSE:300933) as a stock to avoid entirely with its 67.3x P/E ratio. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

As an illustration, earnings have deteriorated at Sinostar Cable 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.

How Is Sinostar Cable's Growth Trending?

Sinostar Cable'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.

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 29%. As a result, earnings from three years ago have also fallen 48% overall. 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 38% shows it's an unpleasant look.

With this information, we find it concerning that Sinostar Cable is trading at a P/E higher than the market. 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. 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

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

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. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.

You should always think about risks. Case in point, we've spotted 4 warning signs for Sinostar Cable you should be aware of, and 2 of them are a bit unpleasant.
