SinoSun Technology Co. Ltd. (SZSE:300333) shares have continued their recent momentum with a 29% gain in the last month alone. The last month tops off a massive increase of 143% in the last year.

Since its price has surged higher, SinoSun Technology may be sending very bearish signals at the moment with a price-to-sales (or "P/S") ratio of 40.9x, since almost half of all companies in the Electronic industry in China have P/S ratios under 4.4x and even P/S lower than 2x are not unusual. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so lofty.

What Does SinoSun Technology's P/S Mean For Shareholders?

SinoSun Technology has been doing a decent job lately as it's been growing revenue at a reasonable pace. One possibility is that the P/S ratio is high because investors think this good revenue growth will be enough to outperform the broader industry in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Revenue Growth Forecasted For SinoSun Technology?

SinoSun Technology's P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

If we review the last year of revenue growth, the company posted a worthy increase of 4.2%. Ultimately though, it couldn't turn around the poor performance of the prior period, with revenue shrinking 25% in total over the last three years. 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 26% shows it's an unpleasant look.

In light of this, it's alarming that SinoSun Technology'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 Key Takeaway

The strong share price surge has lead to SinoSun Technology's P/S soaring as well. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

We've established that SinoSun Technology currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
