Sam-A Aluminium Company, Limited (KRX:006110) Stock Rockets 27% As Investors Are Less Pessimistic Than Expected

Sam-A Aluminium Company, Limited (KRX:006110) shareholders are no doubt pleased to see that the share price has bounced 27% in the last month, although it is still struggling to make up recently lost ground. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 50% in the last twelve months.

Since its price has surged higher, you could be forgiven for thinking Sam-A Aluminium Company is a stock not worth researching with a price-to-sales ratios (or "P/S") of 1.5x, considering almost half the companies in Korea's Metals and Mining industry have P/S ratios below 0.3x. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

How Has Sam-A Aluminium Company Performed Recently?

For instance, Sam-A Aluminium Company'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.

We don't have analyst forecasts, but you can see how recent trends are setting up the company for the future by checking out our free report on Sam-A Aluminium Company's earnings, revenue and cash flow.

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 high as Sam-A Aluminium Company's is when the company's growth is on track to outshine the industry.

Retrospectively, the last year delivered a frustrating 3.3% decrease to the company's top line. This means it has also seen a slide in revenue over the longer-term as revenue is down 13% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

In contrast to the company, the rest of the industry is expected to grow by 4.3% 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 Sam-A Aluminium Company's P/S sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Bottom Line On Sam-A Aluminium Company's P/S

Sam-A Aluminium Company shares have taken a big step in a northerly direction, but its P/S is elevated as a result. 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 examination of Sam-A Aluminium Company revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. 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.
