Celularity Inc. (NASDAQ:CELU) shares have continued their recent momentum with a 29% gain in the last month alone. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 43% over that time.

Even after such a large jump in price, Celularity may still be sending very bullish signals at the moment with its price-to-sales (or "P/S") ratio of 6.1x, since almost half of all companies in the Biotechs industry in the United States have P/S ratios greater than 15.6x and even P/S higher than 73x are not unusual. However, the P/S might be quite low for a reason and it requires further investigation to determine if it's justified.

What Does Celularity's P/S Mean For Shareholders?

For instance, Celularity's receding revenue in recent times would have to be some food for thought. Perhaps the market believes the recent revenue performance isn't good enough to keep up the industry, causing the P/S ratio to suffer. If you 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?

The only time you'd be truly comfortable seeing a P/S as depressed as Celularity's is when the company's growth is on track to lag the industry decidedly.

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 21%. The last three years don't look nice either as the company has shrunk revenue by 8.6% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Comparing that to the industry, which is predicted to deliver 1,123% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's understandable that Celularity's P/S would sit below the majority of other companies. 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 recent revenue trends are already weighing down the shares.

The Key Takeaway

Celularity's recent share price jump still sees fails to bring its P/S alongside the industry median. 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.

As we suspected, our examination of Celularity revealed its shrinking revenue over the medium-term is contributing to its low P/S, given the industry is set to grow. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. Given the current circumstances, it seems unlikely that the share price will experience any significant movement in either direction in the near future if recent medium-term revenue trends persist.
