Rare Earth Magnesium Technology Group Holdings Limited (HKG:601) shares have retraced a considerable 30% in the last month, reversing a fair amount of their solid recent performance. Still, a bad month hasn't completely ruined the past year with the stock gaining 42%, which is great even in a bull market.

Even after such a large drop in price, there still wouldn't be many who think Rare Earth Magnesium Technology Group Holdings' price-to-sales (or "P/S") ratio of 0.2x is worth a mention when the median P/S in Hong Kong's Metals and Mining industry is similar at about 0.5x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

How Is Rare Earth Magnesium Technology Group Holdings' Revenue Growth Trending?

There's an inherent assumption that a company should be matching the industry for P/S ratios like Rare Earth Magnesium Technology Group Holdings' to be considered reasonable.

Taking a look back first, we see that the company managed to grow revenues by a handy 7.7% last year. Ultimately though, it couldn't turn around the poor performance of the prior period, with revenue shrinking 52% in total over the last three years. 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 14% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

In light of this, it's somewhat alarming that Rare Earth Magnesium Technology Group Holdings' 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 Rare Earth Magnesium Technology Group Holdings' P/S Mean For Investors?

Following Rare Earth Magnesium Technology Group Holdings' share price tumble, its P/S is just clinging on to the industry median P/S. 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.

Our look at Rare Earth Magnesium Technology Group Holdings revealed its shrinking revenues over the medium-term haven't impacted the P/S as much as we anticipated, given the industry is set to grow. Even though it matches the industry, we're uncomfortable with the current P/S ratio, as this dismal revenue performance is unlikely to support a more positive sentiment for long. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.
