Insmed Incorporated's (NASDAQ:INSM) Shares Climb 40% But Its Business Is Yet to Catch Up

Insmed Incorporated (NASDAQ:INSM) shareholders would be excited to see that the share price has had a great month, posting a 40% gain and recovering from prior weakness. The last 30 days bring the annual gain to a very sharp 47%.

Since its price has surged higher, Insmed's price-to-sales (or "P/S") ratio of 43.5x might make it look like a strong sell right now compared to other companies in the Biotechs industry in the United States, where around half of the companies have P/S ratios below 8.4x and even P/S below 3x are quite common. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

What Does Insmed's Recent Performance Look Like?

Recent times haven't been great for Insmed as its revenue has been rising slower than most other companies. It might be that many expect the uninspiring revenue performance to recover significantly, which has kept the P/S ratio from collapsing. However, if this isn't the case, investors might get caught out paying too much for the stock.

How Is Insmed's Revenue Growth Trending?

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

If we review the last year of revenue growth, the company posted a terrific increase of 21%. Pleasingly, revenue has also lifted 89% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing revenue over that time.

Shifting to the future, estimates from the analysts covering the company suggest revenue should grow by 77% per annum over the next three years. That's shaping up to be materially lower than the 109% per annum growth forecast for the broader industry.

With this information, we find it concerning that Insmed is trading at a P/S higher than the industry. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. There's a good chance these shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the growth outlook.

The Bottom Line On Insmed's P/S

Insmed's P/S has grown nicely over the last month thanks to a handy boost in the share price. 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 concluded that Insmed currently trades on a much higher than expected P/S since its forecast growth is lower than the wider industry. The weakness in the company's revenue estimate doesn't bode well for the elevated P/S, which could take a fall if the revenue sentiment doesn't improve. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
