Sino Oil and Gas Holdings Limited (HKG:702) shares have had a horrible month, losing 35% after a relatively good period beforehand. To make matters worse, the recent drop has wiped out a year's worth of gains with the share price now back where it started a year ago.

Although its price has dipped substantially, you could still be forgiven for feeling indifferent about Sino Oil and Gas Holdings' P/S ratio of 0.6x, since the median price-to-sales (or "P/S") ratio for the Oil and Gas 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 Sino Oil and Gas Holdings' Recent Performance Look Like?

For example, consider that Sino Oil and Gas Holdings' financial performance has been poor lately as its revenue has been in decline. One possibility is that the P/S is moderate because investors think the company might still do enough to be in line with the broader industry in the near future. 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?

Sino Oil and Gas Holdings' P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 32%. 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 14% in total. So we can start by confirming that the company has generally done a good job of growing revenue over that time, even though it had some hiccups along the way.

When compared to the industry's one-year growth forecast of 1.6%, the most recent medium-term revenue trajectory is noticeably more alluring
