Those holding WLS Holdings Limited (HKG:8021) shares would be relieved that the share price has rebounded 45% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Still, the 30-day jump doesn't change the fact that longer term shareholders have seen their stock decimated by the 50% share price drop in the last twelve months.

Following the firm bounce in price, when almost half of the companies in Hong Kong's Construction industry have price-to-sales ratios (or "P/S") below 0.3x, you may consider WLS Holdings as a stock not worth researching with its 4.3x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so lofty.

How Has WLS Holdings Performed Recently?

As an illustration, revenue has deteriorated at WLS Holdings over the last year, which is not ideal at all. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Revenue Growth Metrics Telling Us About The High P/S?

The only time you'd be truly comfortable seeing a P/S as steep as WLS Holdings' is when the company's growth is on track to outshine the industry decidedly.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 38%. The last three years don't look nice either as the company has shrunk revenue by 17% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

In contrast to the company, the rest of the industry is expected to grow by 12% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we find it worrying that WLS Holdings' P/S exceeds that of its industry peers. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

The Bottom Line On WLS Holdings' P/S

Shares in WLS Holdings have seen a strong upwards swing lately, which has really helped boost its P/S figure. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that WLS Holdings currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
