Some Confidence Is Lacking In GemVax&KAEL Co.,Ltd. (KOSDAQ:082270) As Shares Slide 28%

The GemVax&KAEL Co.,Ltd. (KOSDAQ:082270) share price has softened a substantial 28% over the previous 30 days, handing back much of the gains the stock has made lately. The recent drop has obliterated the annual return, with the share price now down 5.2% over that longer period.

In spite of the heavy fall in price, when almost half of the companies in Korea's Semiconductor industry have price-to-sales ratios (or "P/S") below 1.4x, you may still consider GemVax&KAELLtd as a stock not worth researching with its 8.7x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

How Has GemVax&KAELLtd Performed Recently?

As an illustration, revenue has deteriorated at GemVax&KAELLtd over the last year, which is not ideal at all. 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.

What Are Revenue Growth Metrics Telling Us About The High P/S?

There's an inherent assumption that a company should far outperform the industry for P/S ratios like GemVax&KAELLtd'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 15%. At least revenue has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 62% shows it's noticeably less attractive.

In light of this, it's alarming that GemVax&KAELLtd'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. 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.

What Does GemVax&KAELLtd's P/S Mean For Investors?

A significant share price dive has done very little to deflate GemVax&KAELLtd's very lofty P/S. 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 GemVax&KAELLtd revealed its poor three-year revenue trends aren't detracting from the P/S as much as we though, given they look worse than current industry expectations. Right now we aren't comfortable with the high P/S as this revenue performance isn't likely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these the share price as being reasonable.
