Despite an already strong run, SinoMedia Holding Limited (HKG:623) shares have been powering on, with a gain of 38% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 38% in the last year.

Although its price has surged higher, SinoMedia Holding's price-to-earnings (or "P/E") ratio of 6.7x might still make it look like a buy right now compared to the market in Hong Kong, where around half of the companies have P/E ratios above 10x and even P/E's above 20x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

For example, consider that SinoMedia Holding's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is low because investors think the company won't do enough to avoid underperforming the broader market in the near future. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

How Is SinoMedia Holding's Growth Trending?

SinoMedia Holding's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

Retrospectively, the last year delivered a frustrating 21% decrease to the company's bottom line. As a result, earnings from three years ago have also fallen 26% overall. 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 23% 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 SinoMedia Holding'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. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

The Key Takeaway

Despite SinoMedia Holding's shares building up a head of steam, its P/E still lags most other companies. 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 SinoMedia Holding maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
