Parkson Retail Asia Limited (SGX:O9E) shares have continued their recent momentum with a 36% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 66%.

Even after such a large jump in price, Parkson Retail Asia's price-to-earnings (or "P/E") ratio of 3.4x might still make it look like a strong buy right now compared to the market in Singapore, where around half of the companies have P/E ratios above 14x and even P/E's above 25x are quite common. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

For instance, Parkson Retail Asia's receding earnings in recent times would have to be some food for thought. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. 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.

Does Growth Match The Low P/E?

There's an inherent assumption that a company should far underperform the market for P/E ratios like Parkson Retail Asia's to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 17%. The last three years don't look nice either as the company has shrunk EPS by 62% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 13% shows it's an unpleasant look.

With this information, we are not surprised that Parkson Retail Asia 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. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Key Takeaway

Parkson Retail Asia's recent share price jump still sees its P/E sitting firmly flat on the ground. 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.

As we suspected, our examination of Parkson Retail Asia revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. 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.
