There wouldn't be many who think Unico American Corporation's (NASDAQ:UNAM) price-to-sales (or "P/S") ratio of 0.5x is worth a mention when the median P/S for the Insurance industry in the United States is similar at about 0.9x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

How Has Unico American Performed Recently?

For example, consider that Unico American's financial performance has been poor lately as its revenue has been in decline. Perhaps investors believe the recent revenue performance is enough to keep in line with the industry, which is keeping the P/S from dropping off. If not, then existing shareholders may be a little nervous about the viability of the share price.

How Is Unico American's Revenue Growth Trending?

The only time you'd be comfortable seeing a P/S like Unico American's is when the company's growth is tracking the industry closely.

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 68%. This means it has also seen a slide in revenue over the longer-term as revenue is down 62% in total over the last three years. 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 6.8% 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 somewhat alarming that Unico American's P/S sits in line with the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh on the share price eventually.

The Bottom Line On Unico American's P/S

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 find it unexpected that Unico American trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
