3D Systems Corporation (NYSE:DDD) shareholders are no doubt pleased to see that the share price has bounced 45% in the last month, although it is still struggling to make up recently lost ground. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 23% in the last twelve months.

In spite of the firm bounce in price, when close to half the companies operating in the United States' Machinery industry have price-to-sales ratios (or "P/S") above 2.1x, you may still consider 3D Systems as an enticing stock to check out with its 1x 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 limited.

How Has 3D Systems Performed Recently?

3D Systems hasn't been tracking well recently as its declining revenue compares poorly to other companies, which have seen some growth in their revenues on average. It seems that many are expecting the poor revenue performance to persist, which has repressed the P/S ratio. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

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

In order to justify its P/S ratio, 3D Systems would need to produce sluggish growth that's trailing the industry.

Retrospectively, the last year delivered a frustrating 12% decrease to the company's top line. As a result, revenue from three years ago have also fallen 30% overall. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Turning to the outlook, the next year should bring diminished returns, with revenue decreasing 2.4% as estimated by the four analysts watching the company. Meanwhile, the broader industry is forecast to expand by 19%, which paints a poor picture.

With this information, we are not surprised that 3D Systems is trading at a P/S lower than the industry. Nonetheless, there's no guarantee the P/S has reached a floor yet with revenue going in reverse. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

What Does 3D Systems' P/S Mean For Investors?

The latest share price surge wasn't enough to lift 3D Systems' P/S close to the industry median. 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.

As we suspected, our examination of 3D Systems' analyst forecasts revealed that its outlook for shrinking revenue is contributing to its low P/S. As other companies in the industry are forecasting revenue growth, 3D Systems' poor outlook justifies its low P/S ratio. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.

Don't forget that there may be other risks.
