Those holding SEC Electric Machinery Co., Ltd. (SHSE:603988) shares would be relieved that the share price has rebounded 33% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. The bad news is that even after the stocks recovery in the last 30 days, shareholders are still underwater by about 8.9% over the last year.

Although its price has surged higher, it's still not a stretch to say that SEC Electric Machinery's price-to-sales (or "P/S") ratio of 2.5x right now seems quite "middle-of-the-road" compared to the Electrical industry in China, where the median P/S ratio is around 2.3x. 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.

How SEC Electric Machinery Has Been Performing

For example, consider that SEC Electric Machinery's financial performance has been pretty ordinary lately as revenue growth is non-existent. One possibility is that the P/S is moderate because investors think this benign revenue growth rate might not be enough to outperform the broader industry in the near future. If not, then existing shareholders may be feeling hopeful about the future direction of the share price.

Is There Some Revenue Growth Forecasted For SEC Electric Machinery?

The only time you'd be comfortable seeing a P/S like SEC Electric Machinery's is when the company's growth is tracking the industry closely.

Taking a look back first, we see that there was hardly any revenue growth to speak of for the company over the past year. The lack of growth did nothing to help the company's aggregate three-year performance, which is an unsavory 1.7% drop in revenue. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Comparing that to the industry, which is predicted to deliver 22% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

With this information, we find it concerning that SEC Electric Machinery is trading at a fairly similar P/S compared to the industry. 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 on the share price eventually.

What Does SEC Electric Machinery's P/S Mean For Investors?

SEC Electric Machinery's stock has a lot of momentum behind it lately, which has brought its P/S level with 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 SEC Electric Machinery 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. Even though it matches the industry, we're uncomfortable with the current P/S ratio, as this dismal revenue performance is unlikely to support a more positive sentiment for long. 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.
