Unfortunately for some shareholders, the Sweetgreen, Inc. (NYSE:SG) share price has dived 28% in the last thirty days, prolonging recent pain. For any long-term shareholders, the last month ends a year to forget by locking in a 68% share price decline.

Although its price has dipped substantially, you could still be forgiven for feeling indifferent about Sweetgreen's P/S ratio of 1.5x, since the median price-to-sales (or "P/S") ratio for the Hospitality industry in the United States is also close to 1.6x. 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 Sweetgreen's Recent Performance Look Like?

With revenue growth that's inferior to most other companies of late, Sweetgreen has been relatively sluggish. Perhaps the market is expecting future revenue performance to lift, which has kept the P/S from declining. If not, then existing shareholders may be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The P/S Ratio?

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

Taking a look back first, we see that the company managed to grow revenues by a handy 5.8% last year. Pleasingly, revenue has also lifted 63% in aggregate from three years ago, partly thanks to the last 12 months of growth. Therefore, it's fair to say the revenue growth recently has been superb for the company.

Turning to the outlook, the next three years should generate growth of 14% each year as estimated by the analysts watching the company. With the industry predicted to deliver 14% growth per year, the company is positioned for a comparable revenue result.

In light of this, it's understandable that Sweetgreen's P/S sits in line with the majority of other companies. It seems most investors are expecting to see average future growth and are only willing to pay a moderate amount for the stock.

The Bottom Line On Sweetgreen's P/S

Sweetgreen's plummeting stock price has brought its P/S back to a similar region as 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.

We've seen that Sweetgreen maintains an adequate P/S seeing as its revenue growth figures match the rest of the industry. At this stage investors feel the potential for an improvement or deterioration in revenue isn't great enough to push P/S in a higher or lower direction. Unless these conditions change, they will continue to support the share price at these levels.
