With a price-to-earnings (or "P/E") ratio of 6.4x Atkore Inc. (NYSE:ATKR) may be sending very bullish signals at the moment, given that almost half of all companies in the United States have P/E ratios greater than 20x and even P/E's higher than 36x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

Atkore could be doing better as its earnings have been going backwards lately while most other companies have been seeing positive earnings growth. The P/E is probably low because investors think this poor earnings performance isn't going to get any better. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

Is There Any Growth For Atkore?

Atkore's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Retrospectively, the last year delivered a frustrating 25% decrease to the company's bottom line. Even so, admirably EPS has lifted 62% in aggregate from three years ago, notwithstanding the last 12 months. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Looking ahead now, EPS is anticipated to slump, contracting by 23% during the coming year according to the six analysts following the company. With the market predicted to deliver 15% growth , that's a disappointing outcome.

In light of this, it's understandable that Atkore's P/E would sit below the majority of other companies. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.
