When close to half the companies operating in the Consumer Services industry in the United States have price-to-sales ratios (or "P/S") above 1.5x, you may consider WW International, Inc. (NASDAQ:WW) as an attractive investment with its 0.6x P/S ratio. However, the P/S might be low for a reason and it requires further investigation to determine if it's justified.

How WW International Has Been Performing

WW International could be doing better as its revenue has been going backwards lately while most other companies have been seeing positive revenue growth. It seems that many are expecting the poor revenue performance to persist, which has repressed the P/S ratio. If you still like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Do Revenue Forecasts Match The Low P/S Ratio?

There's an inherent assumption that a company should underperform the industry for P/S ratios like WW International's to be considered reasonable.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 17%. This means it has also seen a slide in revenue over the longer-term as revenue is down 35% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Turning to the outlook, the next three years should generate growth of 7.5% per year as estimated by the seven analysts watching the company. Meanwhile, the rest of the industry is forecast to expand by 14% per annum, which is noticeably more attractive.

With this in consideration, its clear as to why WW International's P/S is falling short industry peers. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.

The Key Takeaway

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.

As we suspected, our examination of WW International's analyst forecasts revealed that its inferior revenue outlook is contributing to its low P/S. Shareholders' pessimism on the revenue prospects for the company seems to be the main contributor to the depressed P/S. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.

Having said that, be aware WW International is showing 4 warning signs in our investment analysis, and 1 of those is a bit unpleasant.
