Despite an already strong run, Delcath Systems, Inc. (NASDAQ:DCTH) shares have been powering on, with a gain of 26% in the last thirty days. The last month tops off a massive increase of 103% in the last year.

Since its price has surged higher, Delcath Systems may be sending very bearish signals at the moment with a price-to-sales (or "P/S") ratio of 23.1x, since almost half of all companies in the Medical Equipment industry in the United States have P/S ratios under 3.2x and even P/S lower than 1.2x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does Delcath Systems' P/S Mean For Shareholders?

With revenue growth that's superior to most other companies of late, Delcath Systems has been doing relatively well. It seems the market expects this form will continue into the future, hence the elevated P/S ratio. However, if this isn't the case, investors might get caught out paying too much for the stock.

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

Delcath Systems' 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.

Taking a look back first, we see that the company's revenues underwent some rampant growth over the last 12 months. Spectacularly, three year revenue growth has also set the world alight, thanks to the last 12 months of incredible growth. So we can start by confirming that the company has done a tremendous job of growing revenue over that time.

Looking ahead now, revenue is anticipated to climb by 131% each year during the coming three years according to the six analysts following the company. Meanwhile, the rest of the industry is forecast to only expand by 9.1% per annum, which is noticeably less attractive.

With this information, we can see why Delcath Systems is trading at such a high P/S compared to the industry. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.
