To the annoyance of some shareholders, Hangjin Technology Co., Ltd. (SZSE:000818) shares are down a considerable 28% in the last month, which continues a horrid run for the company. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 34% in that time.

In spite of the heavy fall in price, you could still be forgiven for thinking Hangjin Technology is a stock to steer clear of with a price-to-sales ratios (or "P/S") of 4x, considering almost half the companies in China's Chemicals industry have P/S ratios below 1.9x. 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.

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

For instance, Hangjin Technology's receding revenue in recent times would have to be some food for thought. 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.

Is There Enough Revenue Growth Forecasted For Hangjin Technology?

Hangjin Technology's P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

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 17%. This has soured the latest three-year period, which nevertheless managed to deliver a decent 7.1% overall rise in revenue. Accordingly, while they would have preferred to keep the run going, shareholders would be roughly 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 26% shows it's noticeably less attractive.

With this information, we find it concerning that Hangjin Technology is trading at a P/S higher than the industry. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. 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 Key Takeaway

Even after such a strong price drop, Hangjin Technology's P/S still exceeds the industry median significantly. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

The fact that Hangjin Technology currently trades on a higher P/S relative to the industry is an oddity, since its recent three-year growth is lower than the wider industry forecast. When we observe slower-than-industry revenue growth alongside a high P/S ratio, we assume there to be a significant risk of the share price decreasing, which would result in a lower P/S ratio. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these the share price as being reasonable.
