There's Reason For Concern Over YEST Co., Ltd.'s (KOSDAQ:122640) Massive 27% Price Jump

YEST Co., Ltd. (KOSDAQ:122640) shareholders would be excited to see that the share price has had a great month, posting a 27% gain and recovering from prior weakness. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 20% over that time.

Following the firm bounce in price, given around half the companies in Korea's Semiconductor industry have price-to-sales ratios (or "P/S") below 1.3x, you may consider YEST as a stock to avoid entirely with its 3.4x 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 YEST Has Been Performing

Revenue has risen firmly for YEST recently, which is pleasing to see. One possibility is that the P/S ratio is high because investors think this respectable revenue growth will be enough to outperform the broader industry in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The High P/S Ratio?

In order to justify its P/S ratio, YEST would need to produce outstanding growth that's well in excess of the industry.

Taking a look back first, we see that the company grew revenue by an impressive 25% last year. Pleasingly, revenue has also lifted 38% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing revenue over that time.

Comparing that to the industry, which is predicted to deliver 32% growth in the next 12 months, the company's momentum is weaker, based on recent medium-term annualised revenue results.

With this information, we find it concerning that YEST is trading at a P/S higher than the industry. 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. 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 YEST's P/S Mean For Investors?

The strong share price surge has lead to YEST's P/S soaring as well. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

Our examination of YEST 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. 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. Unless there is a significant improvement in the company's medium-term performance, it will be difficult to prevent the P/S ratio from declining to a more reasonable level.
