Despite an already strong run, BGMC International Limited (HKG:1693) shares have been powering on, with a gain of 38% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 89% in the last year.

Since its price has surged higher, when almost half of the companies in Hong Kong's Construction industry have price-to-sales ratios (or "P/S") below 0.3x, you may consider BGMC International as a stock probably not worth researching with its 1.1x P/S ratio. However, the P/S might be high for a reason and it requires further investigation to determine if it's justified.

What Does BGMC International's Recent Performance Look Like?

For example, consider that BGMC International's financial performance has been poor lately as its revenue has been in decline. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. However, if this isn't the case, investors might get caught out paying too much for the stock.

Is There Enough Revenue Growth Forecasted For BGMC International?

BGMC International's P/S ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 67%. The last three years don't look nice either as the company has shrunk revenue by 67% in aggregate. 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 13% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

In light of this, it's alarming that BGMC International's P/S sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

The Bottom Line On BGMC International's P/S

BGMC International shares have taken a big step in a northerly direction, but its P/S is elevated as a result. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of BGMC International revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
