Dlg Exhibitions & Events Corporation Limited (SHSE:600826) shareholders would be excited to see that the share price has had a great month, posting a 32% gain and recovering from prior weakness. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 13% over that time.

Even after such a large jump in price, you could still be forgiven for feeling indifferent about Dlg Exhibitions & Events' P/E ratio of 30.3x, since the median price-to-earnings (or "P/E") ratio in China is also close to 30x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

Dlg Exhibitions & Events has been struggling lately as its earnings have declined faster than most other companies. One possibility is that the P/E is moderate because investors think the company's earnings trend will eventually fall in line with most others in the market. You'd much rather the company wasn't bleeding earnings if you still believe in the business. Or at the very least, you'd be hoping it doesn't keep underperforming if your plan is to pick up some stock while it's not in favour.

What Are Growth Metrics Telling Us About The P/E?

There's an inherent assumption that a company should be matching the market for P/E ratios like Dlg Exhibitions & Events' 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 51%. This means it has also seen a slide in earnings over the longer-term as EPS is down 23% 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.

Turning to the outlook, the next three years should generate growth of 35% per year as estimated by the dual analysts watching the company. With the market only predicted to deliver 19% per year, the company is positioned for a stronger earnings result.

In light of this, it's curious that Dlg Exhibitions & Events' P/E sits in line with the majority of other companies. Apparently some shareholders are skeptical of the forecasts and have been accepting lower selling prices.

The Key Takeaway

Dlg Exhibitions & Events' 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 Dlg Exhibitions & Events currently trades on a lower than expected P/E since its forecast growth is higher than the wider market. There could be some unobserved threats to earnings preventing the P/E ratio from matching the positive outlook.
