Boule Diagnostics AB (publ) (STO:BOUL) Shares Fly 31% But Investors Aren't Buying For Growth

Simply Wall St

Boule Diagnostics AB (publ) (STO:BOUL) shares have had a really impressive month, gaining 31% after a shaky period beforehand. The bad news is that even after the stocks recovery in the last 30 days, shareholders are still underwater by about 9.4% over the last year.

In spite of the firm bounce in price, Boule Diagnostics may still look like a strong buying opportunity at present with its price-to-sales (or "P/S") ratio of 0.5x, considering almost half of all companies in the Medical Equipment industry in Sweden have P/S ratios greater than 5.6x and even P/S higher than 10x aren't out of the ordinary. However, the P/S might be quite low for a reason and it requires further investigation to determine if it's justified.

How Has Boule Diagnostics Performed Recently?

Boule Diagnostics could be doing better as its revenue has been going backwards lately while most other companies have been seeing positive revenue growth. 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.

Keen to find out how analysts think Boule Diagnostics' future stacks up against the industry? In that case, our free report is a great place to start.

Do Revenue Forecasts Match The Low P/S Ratio?

Boule Diagnostics' P/S ratio would be typical for a company that's expected to deliver very poor growth or even falling revenue, and importantly, perform much worse than the industry.

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 9.0%. As a result, revenue from three years ago have also fallen 4.9% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Turning to the outlook, the next three years should generate growth of 4.0% each year as estimated by the one analyst watching the company. That's shaping up to be materially lower than the 34% each year growth forecast for the broader industry.

In light of this, it's understandable that Boule Diagnostics' P/S sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Key Takeaway

Even after such a strong price move, Boule Diagnostics' P/S still trails the rest of the industry. 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.

We've established that Boule Diagnostics maintains its low P/S on the weakness of its forecast growth being lower than the wider industry, as expected. Shareholders' pessimism on the revenue prospects for the company seems to be the main contributor to the depressed P/S. It's hard to see the share price rising strongly in the near future under these circumstances.
