When you see that almost half of the companies in the Professional Services industry in China have price-to-sales ratios (or "P/S") below 3.4x, Dark Horse Technology Group Co., Ltd. (SZSE:300688) looks to be giving off strong sell signals with its 20.1x 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 Dark Horse Technology Group Has Been Performing

As an illustration, revenue has deteriorated at Dark Horse Technology Group over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Do Revenue Forecasts Match The High P/S Ratio?

Dark Horse Technology Group'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.

Retrospectively, the last year delivered a frustrating 52% decrease to the company's top line. That put a dampener on the good run it was having over the longer-term as its three-year revenue growth is still a noteworthy 26% in total. 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 that to the industry, which is predicted to deliver 26% growth in the next 12 months, the company's momentum is weaker, based on recent medium-term annualised revenue results.

In light of this, it's alarming that Dark Horse Technology Group's P/S sits above the majority of other companies. 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.

What We Can Learn From Dark Horse Technology Group's P/S?

Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

Our examination of Dark Horse Technology Group 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. 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 there is a significant improvement in the company's medium-term performance, it will be difficult to prevent the P/S ratio from declining to a more reasonable level.

Having said that, be aware Dark Horse Technology Group is showing 2 warning signs in our investment analysis, and 1 of those is concerning.
