The Huazhang Technology Holding Limited (HKG:1673) share price has done very well over the last month, posting an excellent gain of 44%. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

Even after such a large jump in price, there still wouldn't be many who think Huazhang Technology Holding's price-to-sales (or "P/S") ratio of 1x is worth a mention when the median P/S in Hong Kong's Machinery industry is similar at about 0.6x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

What Does Huazhang Technology Holding's P/S Mean For Shareholders?

Huazhang Technology Holding certainly has been doing a great job lately as it's been growing its revenue at a really rapid pace. The P/S is probably moderate because investors think this strong revenue growth might not be enough to outperform the broader industry 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 not quite in favour.

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

There's an inherent assumption that a company should be matching the industry for P/S ratios like Huazhang Technology Holding's to be considered reasonable.

Taking a look back first, we see that the company grew revenue by an impressive 77% last year. Revenue has also lifted 27% in aggregate from three years ago, mostly thanks to the last 12 months of growth. Accordingly, shareholders would have probably been satisfied with the medium-term rates of revenue growth.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 12% shows it's noticeably less attractive.

With this in mind, we find it intriguing that Huazhang Technology Holding's P/S is comparable to that of its industry peers. Apparently many investors in the company are less bearish than recent times would indicate and aren't willing to let go of their stock right now. They may be setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

The Final Word

Its shares have lifted substantially and now Huazhang Technology Holding's P/S is back within range of the industry median. 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 Huazhang Technology Holding's average P/S is a bit surprising since its recent three-year growth is lower than the wider industry forecast. When we see weak revenue with slower than industry growth, we suspect the share price is at risk of declining, bringing the P/S back in line with expectations. Unless the recent medium-term conditions improve, it's hard to accept the current share price as fair value.
