Those holding AMSKY Technology Co., Ltd (SZSE:300521) 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. The bad news is that even after the stocks recovery in the last 30 days, shareholders are still underwater by about 9.7% over the last year.

Since its price has surged higher, given around half the companies in China's Machinery industry have price-to-sales ratios (or "P/S") below 2.8x, you may consider AMSKY Technology as a stock to avoid entirely with its 11.9x P/S ratio. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

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

For instance, AMSKY Technology's receding revenue in recent times would have to be some food for thought. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. However, if this isn't the case, investors might get caught out paying too much for the stock.

Is There Enough Revenue Growth Forecasted For AMSKY Technology?

There's an inherent assumption that a company should far outperform the industry for P/S ratios like AMSKY Technology's to be considered reasonable.

Retrospectively, the last year delivered a frustrating 6.1% decrease to the company's top line. This has erased any of its gains during the last three years, with practically no change in revenue being achieved in total. So it appears to us that the company has had a mixed result in terms of growing revenue over that time.

Comparing that to the industry, which is predicted to deliver 27% growth in the next 12 months, the company's momentum is weaker, based on recent medium-term annualised revenue results.

In light of this, it's alarming that AMSKY Technology's P/S sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates 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 We Can Learn From AMSKY Technology's P/S?

AMSKY Technology's P/S has grown nicely over the last month thanks to a handy boost in the share price. 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 AMSKY Technology currently trades on a higher P/S relative to the industry is an oddity, since its recent three-year growth is lower than the wider industry forecast. When we observe slower-than-industry revenue growth alongside a high P/S ratio, we assume there to be a significant risk of the share price decreasing, which would result in a lower P/S ratio. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these the share price as being reasonable.
