Telecom Digital Holdings Limited (HKG:6033) shares have had a really impressive month, gaining 37% 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 17% over that time.

Although its price has surged higher, given about half the companies in Hong Kong have price-to-earnings ratios (or "P/E's") above 11x, you may still consider Telecom Digital Holdings as an attractive investment with its 6.4x 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 Telecom Digital Holdings over the last year, which is not ideal at all. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

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

Retrospectively, the last year delivered a frustrating 25% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 58% in aggregate. 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 22% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we are not surprised that Telecom Digital Holdings is trading at a P/E lower than the market. However, we think shrinking earnings are unlikely to lead to a stable P/E over the longer term, which could set up shareholders for future disappointment. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

The Bottom Line On Telecom Digital Holdings' P/E

Telecom Digital Holdings' stock might have been given a solid boost, but its P/E certainly hasn't reached any great heights. 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 Telecom Digital Holdings 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.
