You may think that with a price-to-sales (or "P/S") ratio of 0.1x Traffic Technologies Limited (ASX:TTI) is definitely a stock worth checking out, seeing as almost half of all the Infrastructure companies in Australia have P/S ratios greater than 2.3x and even P/S above 9x 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.

What Does Traffic Technologies' Recent Performance Look Like?

As an illustration, revenue has deteriorated at Traffic Technologies over the last year, which is not ideal at all. One possibility is that the P/S is low because investors think the company won't do enough to avoid underperforming the broader industry in the near future. 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.

How Is Traffic Technologies' Revenue Growth Trending?

The only time you'd be truly comfortable seeing a P/S as depressed as Traffic Technologies' 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 45%. As a result, revenue from three years ago have also fallen 39% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

In contrast to the company, the rest of the industry is expected to grow by 9.4% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we understand why Traffic Technologies' P/S is lower than most of its industry peers. 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 Final Word

We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

It's no surprise that Traffic Technologies maintains its low P/S off the back of its sliding revenue over the medium-term. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises either. If recent medium-term revenue trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.
