When you see that almost half of the companies in the Communications industry in the United States have price-to-sales ratios (or "P/S") below 1.1x, NetScout Systems, Inc. (NASDAQ:NTCT) looks to be giving off some sell signals with its 1.8x 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 as high as it is.

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

While the industry has experienced revenue growth lately, NetScout Systems' revenue has gone into reverse gear, which is not great. It might be that many expect the dour revenue performance to recover substantially, 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.

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

The only time you'd be truly comfortable seeing a P/S as high as NetScout Systems' is when the company's growth is on track to outshine the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 14%. The last three years don't look nice either as the company has shrunk revenue by 5.4% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Looking ahead now, revenue is anticipated to climb by 2.6% during the coming year according to the lone analyst following the company. Meanwhile, the rest of the industry is forecast to expand by 7.6%, which is noticeably more attractive.

With this information, we find it concerning that NetScout Systems is trading at a P/S higher than the industry. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. There's a good chance these shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the growth outlook.

The Key Takeaway

It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

It comes as a surprise to see NetScout Systems trade at such a high P/S given the revenue forecasts look less than stellar. When we see a weak revenue outlook, we suspect the share price faces a much greater risk of declining, bringing back down the P/S figures. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
