Those holding Hangzhou Century Co., Ltd (SZSE:300078) shares would be relieved that the share price has rebounded 31% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 37% over that time.

Even after such a large jump in price, there still wouldn't be many who think Hangzhou Century's price-to-sales (or "P/S") ratio of 2.7x is worth a mention when the median P/S in China's Electronic industry is similar at about 3.3x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

How Has Hangzhou Century Performed Recently?

For example, consider that Hangzhou Century's financial performance has been pretty ordinary lately as revenue growth is non-existent. Perhaps the market believes the recent run-of-the-mill revenue performance isn't enough to outperform the industry, which has kept the P/S muted. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

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

Hangzhou Century's 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.

If we review the last year of revenue, the company posted a result that saw barely any deviation from a year ago. Whilst it's an improvement, it wasn't enough to get the company out of the hole it was in, with revenue down 33% overall from three years ago. 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 25% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's somewhat alarming that Hangzhou Century's P/S sits in line with 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 on the share price eventually.

What Does Hangzhou Century's P/S Mean For Investors?

Its shares have lifted substantially and now Hangzhou Century's P/S is back within range of the industry median. 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.

We find it unexpected that Hangzhou Century trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.
