Those holding Hangzhou Kaierda Welding Robot Co.,Ltd. (SHSE:688255) shares would be relieved that the share price has rebounded 47% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 14% over that time.

After such a large jump in price, when almost half of the companies in China's Machinery industry have price-to-sales ratios (or "P/S") below 2.8x, you may consider Hangzhou Kaierda Welding RobotLtd as a stock not worth researching with its 5.5x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so lofty.

What Does Hangzhou Kaierda Welding RobotLtd's P/S Mean For Shareholders?

The revenue growth achieved at Hangzhou Kaierda Welding RobotLtd over the last year would be more than acceptable for most companies. 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. 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?

Hangzhou Kaierda Welding RobotLtd's P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

If we review the last year of revenue growth, the company posted a terrific increase of 22%. However, this wasn't enough as the latest three year period has seen the company endure a nasty 19% drop in revenue in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Comparing that to the industry, which is predicted to deliver 28% 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 Hangzhou Kaierda Welding RobotLtd's P/S sits above the majority of other companies. 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. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Final Word

Shares in Hangzhou Kaierda Welding RobotLtd have seen a strong upwards swing lately, which has really helped boost its P/S figure. 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.

Our examination of Hangzhou Kaierda Welding RobotLtd 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. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.
