There wouldn't be many who think Taiyuan Heavy Industry Co., Ltd.'s (SHSE:600169) price-to-earnings (or "P/E") ratio of 34.3x is worth a mention when the median P/E in China is similar at about 31x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

Recent times have been quite advantageous for Taiyuan Heavy Industry as its earnings have been rising very briskly. It might be that many expect the strong earnings performance to wane, which has kept the P/E from rising. If that doesn't eventuate, then existing shareholders have reason to be feeling optimistic about the future direction of the share price.

Does Growth Match The P/E?

Taiyuan Heavy Industry's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

If we review the last year of earnings growth, the company posted a terrific increase of 464%. Still, EPS has barely risen at all from three years ago in total, which is not ideal. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

This is in contrast to the rest of the market, which is expected to grow by 42% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's curious that Taiyuan Heavy Industry's P/E sits in line with the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are willing to pay up for exposure to the stock. They may be setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

What We Can Learn From Taiyuan Heavy Industry's P/E?

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.

We've established that Taiyuan Heavy Industry currently trades on a higher than expected P/E since its recent three-year growth is lower than the wider market forecast. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
