When close to half the companies in China have price-to-earnings ratios (or "P/E's") above 35x, you may consider Wasu Media Holding Co.,Ltd (SZSE:000156) as an attractive investment with its 19.7x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

As an illustration, earnings have deteriorated at Wasu Media HoldingLtd over the last year, which is not ideal at all. 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. 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 out of favour.

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

The only time you'd be truly comfortable seeing a P/E as low as Wasu Media HoldingLtd's is when the company's growth is on track to lag the market.

Retrospectively, the last year delivered a frustrating 12% decrease to the company's bottom line. As a result, earnings from three years ago have also fallen 16% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

In contrast to the company, the rest of the market is expected to grow by 44% 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 Wasu Media HoldingLtd'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.

What We Can Learn From Wasu Media HoldingLtd'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 Wasu Media HoldingLtd maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected.

Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
