PanAsialum Holdings Company Limited (HKG:2078) shareholders that were waiting for something to happen have been dealt a blow with a 30% 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 20% in that time.

Although its price has dipped substantially, you could still be forgiven for feeling indifferent about PanAsialum Holdings' P/S ratio of 0.1x, since the median price-to-sales (or "P/S") ratio for the Electronic industry in Hong Kong is also close to 0.4x. 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.

What Does PanAsialum Holdings' Recent Performance Look Like?

For example, consider that PanAsialum Holdings' 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 not, then existing shareholders may be a little nervous about the viability of the share price.

What Are Revenue Growth Metrics Telling Us About The P/S?

In order to justify its P/S ratio, PanAsialum Holdings would need to produce growth that's similar to the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 11%. This means it has also seen a slide in revenue over the longer-term as revenue is down 49% 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 22% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we find it worrying that PanAsialum Holdings' P/S exceeds that of its industry peers. 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 PanAsialum Holdings' P/S Mean For Investors?

PanAsialum Holdings' plummeting stock price has brought its P/S back to a similar region as the rest of the industry. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

The fact that PanAsialum 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. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
