Those holding ShenZhen Consys Science&Technology Co., Ltd. (SHSE:688788) shares would be relieved that the share price has rebounded 26% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 32% in the last twelve months.

Since its price has surged higher, ShenZhen Consys Science&Technology's price-to-sales (or "P/S") ratio of 13.6x might make it look like a strong sell right now compared to other companies in the Aerospace & Defense industry in China, where around half of the companies have P/S ratios below 7.9x and even P/S below 3x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does ShenZhen Consys Science&Technology's P/S Mean For Shareholders?

It looks like revenue growth has deserted ShenZhen Consys Science&Technology recently, which is not something to boast about. It might be that many are expecting an improvement to the uninspiring revenue performance over the coming period, which has kept the P/S from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

The only time you'd be truly comfortable seeing a P/S as steep as ShenZhen Consys Science&Technology's is when the company's growth is on track to outshine the industry decidedly.

Taking a look back first, we see that there was hardly any revenue growth to speak of for the company over the past year. This isn't what shareholders were looking for as it means they've been left with a 64% decline in revenue over the last three years in total. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

In contrast to the company, the rest of the industry is expected to grow by 48% 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 ShenZhen Consys Science&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.

What Does ShenZhen Consys Science&Technology's P/S Mean For Investors?

Shares in ShenZhen Consys Science&Technology have seen a strong upwards swing lately, which has really helped boost its P/S figure. 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.

We've established that ShenZhen Consys Science&Technology currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. 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.
