Tat Hong Equipment Service Co., Ltd. (HKG:2153) shareholders that were waiting for something to happen have been dealt a blow with a 25% share price drop in the last month. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 11% in that time.

Although its price has dipped substantially, you could still be forgiven for thinking Tat Hong Equipment Service is a stock not worth researching with a price-to-sales ratios (or "P/S") of 1.4x, considering almost half the companies in Hong Kong's Construction industry have P/S ratios below 0.4x. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's as high as it is.

How Tat Hong Equipment Service Has Been Performing

For instance, Tat Hong Equipment Service's receding revenue in recent times would have to be some food for thought. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. If not, then existing shareholders may be quite nervous about the viability of the share price.

Do Revenue Forecasts Match The High P/S Ratio?

In order to justify its P/S ratio, Tat Hong Equipment Service would need to produce impressive growth in excess of the industry.

Retrospectively, the last year delivered a frustrating 11% decrease to the company's top line. At least revenue has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Comparing that to the industry, which is predicted to deliver 16% growth in the next 12 months, the company's momentum is weaker, based on recent medium-term annualised revenue results.

With this in mind, we find it worrying that Tat Hong Equipment Service'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 good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

The Bottom Line On Tat Hong Equipment Service's P/S

Despite the recent share price weakness, Tat Hong Equipment Service's P/S remains higher than most other companies in the industry. 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.

Our examination of Tat Hong Equipment Service revealed its poor three-year revenue trends aren't detracting from the P/S as much as we though, given they look worse than current industry expectations. Right now we aren't comfortable with the high P/S as this revenue performance isn't likely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these the share price as being reasonable.
