Despite an already strong run, Xinda Investment Holdings Limited (HKG:1281) shares have been powering on, with a gain of 27% in the last thirty days. Unfortunately, despite the strong performance over the last month, the full year gain of 9.2% isn't as attractive.

Although its price has surged higher, you could still be forgiven for feeling indifferent about Xinda Investment Holdings' P/S ratio of 0.9x, since the median price-to-sales (or "P/S") ratio for the Renewable Energy industry in Hong Kong is also close to 0.7x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

What Does Xinda Investment Holdings' Recent Performance Look Like?

For instance, Xinda Investment Holdings' receding revenue in recent times would have to be some food for thought. 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.

Do Revenue Forecasts Match The P/S Ratio?

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

Retrospectively, the last year delivered a frustrating 42% decrease to the company's top line. This means it has also seen a slide in revenue over the longer-term as revenue is down 71% 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 5.0% 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 Xinda Investment Holdings' 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.

What Does Xinda Investment Holdings' P/S Mean For Investors?

Xinda Investment Holdings' stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the industry. 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.

The fact that Xinda Investment Holdings currently trades at a P/S on par with the rest of the industry is surprising to us since its recent revenues have been in decline over the medium-term, all while the industry is set 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.
