Unfortunately for some shareholders, the Gulf Resources, Inc. (NASDAQ:GURE) share price has dived 29% in the last thirty days, prolonging recent pain. For any long-term shareholders, the last month ends a year to forget by locking in a 57% share price decline.

Since its price has dipped substantially, when close to half the companies operating in the United States' Chemicals industry have price-to-sales ratios (or "P/S") above 1.4x, you may consider Gulf Resources as an enticing stock to check out with its 0.5x P/S ratio. However, the P/S might be low for a reason and it requires further investigation to determine if it's justified.

What Does Gulf Resources' P/S Mean For Shareholders?

For example, consider that Gulf Resources' financial performance has been poor lately as its revenue has been in decline. One possibility is that the P/S is low because investors think the company won't do enough to avoid underperforming the broader industry in the near future. However, if this doesn't eventuate 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?

Gulf Resources' P/S ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than 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 72%. The last three years don't look nice either as the company has shrunk revenue by 58% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 3.5% shows it's an unpleasant look.

In light of this, it's understandable that Gulf Resources' 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 Bottom Line On Gulf Resources' P/S

Gulf Resources' recently weak share price has pulled its P/S back below other Chemicals companies. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Gulf Resources confirms that the company's shrinking revenue over the past medium-term is a key factor in its low price-to-sales ratio, given the industry is projected to grow. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises either. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
