Contel Technology Company Limited (HKG:1912) shareholders are no doubt pleased to see that the share price has bounced 27% in the last month, although it is still struggling to make up recently lost ground. But the gains over the last month weren't enough to make shareholders whole, as the share price is still down 7.1% in the last twelve months.

Even after such a large jump in price, it's still not a stretch to say that Contel Technology's price-to-sales (or "P/S") ratio of 0.1x right now seems quite "middle-of-the-road" compared to the Electronic industry in Hong Kong, where the median P/S ratio is around 0.5x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

How Has Contel Technology Performed Recently?

For example, consider that Contel Technology's financial performance has been poor lately as its revenue has been in decline. It might be that many expect the company to put the disappointing revenue performance behind them over the coming period, which has kept the P/S from falling. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

How Is Contel Technology's Revenue Growth Trending?

The only time you'd be comfortable seeing a P/S like Contel Technology's is when the company's growth is tracking the industry closely.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 46%. This means it has also seen a slide in revenue over the longer-term as revenue is down 57% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

In contrast to the company, the rest of the industry is expected to grow by 19% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

In light of this, it's somewhat alarming that Contel Technology's P/S sits in line with the majority of other companies. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh on the share price eventually.

The Final Word

Its shares have lifted substantially and now Contel Technology's P/S is back within range of the industry median. 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.

We find it unexpected that Contel Technology trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected to grow. Even though it matches the industry, we're uncomfortable with the current P/S ratio, as this dismal revenue performance is unlikely to support a more positive sentiment for long. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.

Having said that, be aware Contel Technology is showing 4 warning signs in our investment analysis, and 3 of those are potentially serious.
