With a price-to-earnings (or "P/E") ratio of 22.9x Shanghai Golden Union Commercial Management Co.,Ltd. (SHSE:603682) may be sending bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 32x and even P/E's higher than 60x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

For example, consider that Shanghai Golden Union Commercial ManagementLtd's financial performance has been pretty ordinary lately as earnings growth is non-existent. It might be that many expect the uninspiring earnings performance to worsen, which has repressed the P/E. If not, then existing shareholders may be feeling optimistic about the future direction of the share price.

How Is Shanghai Golden Union Commercial ManagementLtd's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as low as Shanghai Golden Union Commercial ManagementLtd's is when the company's growth is on track to lag the market.

Taking a look back first, we see that there was hardly any earnings per share growth to speak of for the company over the past year. This isn't what shareholders were looking for as it means they've been left with a 40% decline in EPS over the last three years in total. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 38% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's understandable that Shanghai Golden Union Commercial ManagementLtd's P/E would sit below the majority of other companies. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Key Takeaway

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Shanghai Golden Union Commercial ManagementLtd maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. If recent medium-term earnings trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.

You should always think about risks. Case in point, we've spotted 2 warning signs for Shanghai Golden Union Commercial ManagementLtd you should be aware of, and 1 of them doesn't sit too well with us.
