There's Reason For Concern Over Nanjing Sample Technology Company Limited's (HKG:1708) Massive 72% Price Jump

Nanjing Sample Technology Company Limited (HKG:1708) shares have had a really impressive month, gaining 72% after a shaky period beforehand. Looking back a bit further, it's encouraging to see the stock is up 32% in the last year.

Although its price has surged higher, there still wouldn't be many who think Nanjing Sample Technology's price-to-sales (or "P/S") ratio of 0.7x is worth a mention when the median P/S in Hong Kong's Electronic industry is similar at about 0.5x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

What Does Nanjing Sample Technology's Recent Performance Look Like?

For example, consider that Nanjing Sample Technology's financial performance has been poor lately as its revenue has been in decline. One possibility is that the P/S is moderate because investors think the company might still do enough to be in line with the broader industry in the near future. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

How Is Nanjing Sample Technology's Revenue Growth Trending?

Nanjing Sample Technology's P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 8.0%. As a result, revenue from three years ago have also fallen 56% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 18% shows it's an unpleasant look.

In light of this, it's somewhat alarming that Nanjing Sample Technology's P/S sits in line with the majority of other companies. It seems most investors are ignoring the recent poor growth rate 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 on the share price eventually.

The Final Word

Nanjing Sample Technology's stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of 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 Nanjing Sample Technology currently trades at a P/S on par with the rest of the industry is surprising to us since its recent revenues have been in decline over the medium-term, all while the industry is set to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
