Pinning Down EM-Tech.CO., LTD.'s (KOSDAQ:091120) P/S Is Difficult Right Now

When close to half the companies in the Electronic industry in Korea have price-to-sales ratios (or "P/S") below 0.9x, you may consider EM-Tech.CO., LTD. (KOSDAQ:091120) as a stock to potentially avoid with its 2.4x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

How Has EM-Tech.CO Performed Recently?

For instance, EM-Tech.CO'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.

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 EM-Tech.CO's is when the company's growth is on track to outshine the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 37%. This means it has also seen a slide in revenue over the longer-term as revenue is down 30% 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.

Comparing that to the industry, which is predicted to deliver 17% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's alarming that EM-Tech.CO'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.

The Key Takeaway

Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of EM-Tech.CO 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. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.

You always need to take note of risks, for example - EM-Tech.CO has 1 warning sign we think you should be aware of.
