Enertork Ltd.'s (KOSDAQ:019990) 28% Share Price Plunge Could Signal Some Risk

Enertork Ltd. (KOSDAQ:019990) shareholders won't be pleased to see that the share price has had a very rough month, dropping 28% and undoing the prior period's positive performance. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 30% share price drop.

Although its price has dipped substantially, when almost half of the companies in Korea's Electrical industry have price-to-sales ratios (or "P/S") below 0.9x, you may still consider Enertork as a stock probably not worth researching with its 1.8x 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.

What Does Enertork's P/S Mean For Shareholders?

For instance, Enertork's receding revenue in recent times would have to be some food for thought. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Do Revenue Forecasts Match The High P/S Ratio?

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

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 8.6%. This has soured the latest three-year period, which nevertheless managed to deliver a decent 13% overall rise in revenue. Although it's been a bumpy ride, it's still fair to say the revenue growth recently has been mostly respectable for the company.

This is in contrast to the rest of the industry, which is expected to grow by 14% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that Enertork'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. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

The Bottom Line On Enertork's P/S

Despite the recent share price weakness, Enertork's P/S remains higher than most other companies in the industry. 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.

The fact that Enertork 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. If recent medium-term revenue trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
