Wai Chi Holdings Company Limited (HKG:1305) shareholders are no doubt pleased to see that the share price has bounced 25% in the last month, although it is still struggling to make up recently lost ground. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 21% in the last twelve months.

In spite of the firm bounce in price, Wai Chi Holdings may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 5.1x, since almost half of all companies in Hong Kong have P/E ratios greater than 10x and even P/E's higher than 20x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

As an illustration, earnings have deteriorated at Wai Chi Holdings 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.

How Is Wai Chi Holdings' Growth Trending?

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

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 29%. The last three years don't look nice either as the company has shrunk EPS by 10% 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 Wai Chi Holdings is trading at a P/E lower than the market. 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.

What We Can Learn From Wai Chi Holdings' P/E?

Despite Wai Chi Holdings' shares building up a head of steam, its P/E still lags most other companies. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

As we suspected, our examination of Wai Chi Holdings revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
