To the annoyance of some shareholders, Tandem Diabetes Care, Inc. (NASDAQ:TNDM) shares are down a considerable 27% in the last month, which continues a horrid run for the company. Looking at the bigger picture, even after this poor month the stock is up 54% in the last year.

Since its price has dipped substantially, Tandem Diabetes Care may be sending buy signals at present with its price-to-sales (or “P/S”) ratio of 2.1x, considering almost half of all companies in the Medical Equipment industry in the United States have P/S ratios greater than 3.2x and even P/S higher than 7x aren’t out of the ordinary. Although, it’s not wise to just take the P/S at face value as there may be an explanation why it’s limited.

How Is Tandem Diabetes Care’s Revenue Growth Trending?

There’s an inherent assumption that a company should underperform the industry for P/S ratios like Tandem Diabetes Care’s to be considered reasonable.

Retrospectively, the last year delivered a decent 11% gain to the company’s revenues. The latest three year period has also seen a 29% overall rise in revenue, aided somewhat by its short-term performance. Therefore, it’s fair to say the revenue growth recently has been respectable for the company.

Shifting to the future, estimates from the analysts covering the company suggest revenue should grow by 12% per annum over the next three years. With the industry only predicted to deliver 9.2% per annum, the company is positioned for a stronger revenue result.

With this information, we find it odd that Tandem Diabetes Care is trading at a P/S lower than the industry. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

What We Can Learn From Tandem Diabetes Care’s P/S?

The southerly movements of Tandem Diabetes Care’s shares means its P/S is now sitting at a pretty low level. While the price-to-sales ratio shouldn’t be the defining factor in whether you buy a stock or not, it’s quite a capable barometer of revenue expectations.
