Atrion Corporation's (NASDAQ:ATRI) 26% Share Price Surge Not Quite Adding Up

Those holding Atrion Corporation (NASDAQ:ATRI) shares would be relieved that the share price has rebounded 26% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 33% in the last twelve months.

Following the firm bounce in price, Atrion may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 32.3x, since almost half of all companies in the United States have P/E ratios under 16x and even P/E's lower than 9x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

For example, consider that Atrion's financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Atrion's Growth Trending?

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

Retrospectively, the last year delivered a frustrating 38% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 32% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 10% shows it's an unpleasant look.

In light of this, it's alarming that Atrion's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Final Word

Atrion's P/E is flying high just like its stock has during the last month. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Atrion revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
