Yixin Group Limited (HKG:2858) shares have had a really impressive month, gaining 36% after a shaky period beforehand. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 45% over that time.

Although its price has surged higher, you could still be forgiven for feeling indifferent about Yixin Group's P/E ratio of 7.7x, since the median price-to-earnings (or "P/E") ratio in Hong Kong is also close to 9x. 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 Yixin Group 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 you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

How Is Yixin Group's Growth Trending?

The only time you'd be comfortable seeing a P/E like Yixin Group's is when the company's growth is tracking the market closely.

Taking a look back first, we see that the company grew earnings per share by an impressive 77% last year. Still, EPS has barely risen at all from three years ago in total, which is not ideal. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

This is in contrast to the rest of the market, which is expected to grow by 23% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's curious that Yixin Group'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.

The Bottom Line On Yixin Group's P/E

Yixin Group's stock has a lot of momentum behind it lately, which has brought its P/E level with the market. 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 Yixin Group 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.
