Design Capital Limited (HKG:1545) shareholders would be excited to see that the share price has had a great month, posting a 27% 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 21% over that time.

Even after such a large jump in price, you could still be forgiven for feeling indifferent about Design Capital's P/E ratio of 9.6x, since the median price-to-earnings (or "P/E") ratio in Hong Kong is also close to 9x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

As an illustration, earnings have deteriorated at Design Capital over the last year, which is not ideal at all. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

The only time you'd be comfortable seeing a P/E like Design Capital's is when the company's growth is tracking the market closely.

Retrospectively, the last year delivered a frustrating 35% decrease to the company's bottom line. As a result, earnings from three years ago have also fallen 36% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 17% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's somewhat alarming that Design Capital's P/E sits in line with the majority of other companies. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Bottom Line On Design Capital's P/E

Design Capital appears to be back in favour with a solid price jump getting its P/E back in line with most other companies. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Design Capital revealed its shrinking earnings over the medium-term aren't impacting its P/E as much as we would have predicted, given the market is set to grow. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the moderate P/E lower. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.

Don't forget that there may be other risks. For instance, we've identified 4 warning signs for Design Capital that you should be aware of.
