Zhuhai Aerospace Microchips Science & Technology Co., Ltd. (SZSE:300053) shares have had a really impressive month, gaining 26% after a shaky period beforehand. Looking further back, the 21% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

Following the firm bounce in price, Zhuhai Aerospace Microchips Science & Technology's price-to-sales (or "P/S") ratio of 23.3x might make it look like a strong sell right now compared to other companies in the Semiconductor industry in China, where around half of the companies have P/S ratios below 6.4x and even P/S below 3x are quite common. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

What Does Zhuhai Aerospace Microchips Science & Technology's Recent Performance Look Like?

For instance, Zhuhai Aerospace Microchips Science & Technology's receding revenue in recent times would have to be some food for thought. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Zhuhai Aerospace Microchips Science & Technology's Revenue Growth Trending?

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

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 29%. As a result, revenue from three years ago have also fallen 55% overall. 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 33% 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 Zhuhai Aerospace Microchips 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.
