There's Reason For Concern Over Productive Technologies Company Limited's (HKG:650) Massive 28% Price Jump

The Productive Technologies Company Limited (HKG:650) share price has done very well over the last month, posting an excellent gain of 28%. Taking a wider view, although not as strong as the last month, the full year gain of 20% is also fairly reasonable.

Since its price has surged higher, when almost half of the companies in Hong Kong's Semiconductor industry have price-to-sales ratios (or "P/S") below 3x, you may consider Productive Technologies as a stock not worth researching with its 9.3x 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 Productive Technologies Has Been Performing

As an illustration, revenue has deteriorated at Productive Technologies over the last year, which is not ideal at all. 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Productive Technologies' Revenue Growth Trending?

The only time you'd be truly comfortable seeing a P/S as steep as Productive Technologies' is when the company's growth is on track to outshine the industry decidedly.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 47%. The last three years don't look nice either as the company has shrunk revenue by 62% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Comparing that to the industry, which is predicted to deliver 21% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

With this information, we find it concerning that Productive Technologies 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.

The Final Word

Productive Technologies' P/S has grown nicely over the last month thanks to a handy boost in the share price. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our examination of Productive Technologies 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. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
