AMOS Group Limited (SGX:49B) shares have had a horrible month, losing 26% after a relatively good period beforehand. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 43% share price drop.

Since its price has dipped substantially, given about half the companies operating in Singapore's Energy Services industry have price-to-sales ratios (or "P/S") above 0.9x, you may consider AMOS Group as an attractive investment with its 0.2x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

What Does AMOS Group's P/S Mean For Shareholders?

For example, consider that AMOS Group's financial performance has been pretty ordinary lately as revenue growth is non-existent. Perhaps the market believes the recent lacklustre revenue performance is a sign of future underperformance relative to industry peers, hurting the P/S. If not, then existing shareholders may be feeling optimistic about the future direction of the share price.

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

The only time you'd be truly comfortable seeing a P/S as low as AMOS Group's is when the company's growth is on track to lag the industry.

Taking a look back first, we see that there was hardly any revenue growth to speak of for the company over the past year. This isn't what shareholders were looking for as it means they've been left with a 23% decline in revenue over the last three years in total. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 17% shows it's an unpleasant look.

In light of this, it's understandable that AMOS Group's P/S would sit below the majority of other companies. However, we think shrinking revenues are unlikely to lead to a stable P/S over the longer term, which could set up shareholders for future disappointment. Even just maintaining these prices could be difficult to achieve as recent revenue trends are already weighing down the shares.

The Key Takeaway

The southerly movements of AMOS Group's shares means its P/S is now sitting at a pretty low level. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

As we suspected, our examination of AMOS Group revealed its shrinking revenue over the medium-term is contributing to its low P/S, given the industry is set to grow. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
