Optimistic Investors Push SG Corporation (KRX:004060) Shares Up 25% But Growth Is Lacking

Simply Wall St

SG Corporation (KRX:004060) shareholders have had their patience rewarded with a 25% share price jump in the last month. Looking further back, the 17% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

Even after such a large jump in price, you could still be forgiven for feeling indifferent about SG's P/S ratio of 0.6x, since the median price-to-sales (or "P/S") ratio for the Luxury industry in Korea is also close to 0.4x. 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.

What Does SG's Recent Performance Look Like?

As an illustration, revenue has deteriorated at SG over the last year, which is not ideal at all. It might be that many expect the company to put the disappointing revenue performance behind them over the coming period, which has kept the P/S from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

Is There Some Revenue Growth Forecasted For SG?

The only time you'd be comfortable seeing a P/S like SG's is when the company's growth is tracking the industry closely.

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 4.9%. As a result, revenue from three years ago have also fallen 18% overall. 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 2.9% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we find it worrying that SG's P/S exceeds that of its industry peers. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. 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.

The Key Takeaway

SG appears to be back in favour with a solid price jump bringing its P/S back in line with other companies in the industry While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

We find it unexpected that SG trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected 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. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
