To the annoyance of some shareholders, Naseej International Trading Company (TADAWUL:1213) shares are down a considerable 27% in the last month, which continues a horrid run for the company. For any long-term shareholders, the last month ends a year to forget by locking in a 68% share price decline.

Although its price has dipped substantially, when almost half of the companies in Saudi Arabia's Consumer Durables industry have price-to-sales ratios (or "P/S") below 1.1x, you may still consider Naseej International Trading as a stock not worth researching with its 3.5x P/S ratio. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

How Naseej International Trading Has Been Performing

As an illustration, revenue has deteriorated at Naseej International Trading 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

In order to justify its P/S ratio, Naseej International Trading would need to produce outstanding growth that's well in excess of the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 54%. As a result, revenue from three years ago have also fallen 61% overall. 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 6.8% 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 Naseej International Trading's 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. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

What We Can Learn From Naseej International Trading's P/S?

A significant share price dive has done very little to deflate Naseej International Trading's very lofty P/S. 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.

Our examination of Naseej International Trading revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. 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.

Don't forget that there may be other risks.
