Diagnostic Medical Systems S.A.'s (EPA:ALDMS) Shares Leap 32% Yet They're Still Not Telling The Full Story

Diagnostic Medical Systems S.A. (EPA:ALDMS) shareholders would be excited to see that the share price has had a great month, posting a 32% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 14% in the last twelve months.

In spite of the firm bounce in price, given about half the companies operating in France's Medical Equipment industry have price-to-sales ratios (or "P/S") above 2x, you may still consider Diagnostic Medical Systems as an attractive investment with its 0.4x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

What Does Diagnostic Medical Systems' P/S Mean For Shareholders?

The revenue growth achieved at Diagnostic Medical Systems over the last year would be more than acceptable for most companies. Perhaps the market is expecting this acceptable revenue performance to take a dive, which has kept the P/S suppressed. 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?

There's an inherent assumption that a company should underperform the industry for P/S ratios like Diagnostic Medical Systems' to be considered reasonable.

Taking a look back first, we see that the company grew revenue by an impressive 17% last year. Revenue has also lifted 25% in aggregate from three years ago, mostly thanks to the last 12 months of growth. Accordingly, shareholders would have probably been satisfied with the medium-term rates of revenue growth.

Weighing that recent medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 6.4% shows it's about the same on an annualised basis.

With this information, we find it odd that Diagnostic Medical Systems is trading at a P/S lower than the industry. Apparently some shareholders are more bearish than recent times would indicate and have been accepting lower selling prices.

The Final Word

The latest share price surge wasn't enough to lift Diagnostic Medical Systems' P/S close to the industry median. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Diagnostic Medical Systems revealed its three-year revenue trends looking similar to current industry expectations hasn't given the P/S the boost we expected, given that it's lower than the wider industry P/S, When we see industry-like revenue growth but a lower than expected P/S, we assume potential risks are what might be placing downward pressure on the share price. It appears some are indeed anticipating revenue instability, because the persistence of these recent medium-term conditions should normally provide more support to the share price.

You should always think about risks. Case in point, we've spotted 4 warning signs for Diagnostic Medical Systems you should be aware of, and 2 of them are a bit unpleasant.
