Federal Agricultural Mortgage Corporation's (NYSE:AGM) price-to-earnings (or "P/E") ratio of 10.5x might make it look like a buy right now compared to the market in the United States, where around half of the companies have P/E ratios above 17x and even P/E's above 30x are quite common. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Is There Any Growth For Federal Agricultural Mortgage?

There's an inherent assumption that a company should underperform the market for P/E ratios like Federal Agricultural Mortgage's to be considered reasonable.

If we review the last year of earnings growth, the company posted a worthy increase of 4.0%. The latest three year period has also seen an excellent 60% overall rise in EPS, aided somewhat by its short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.

Shifting to the future, estimates from the three analysts covering the company suggest earnings should grow by 8.1% each year over the next three years. That's shaping up to be materially lower than the 11% per year growth forecast for the broader market.

In light of this, it's understandable that Federal Agricultural Mortgage's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Key Takeaway

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

We've established that Federal Agricultural Mortgage maintains its low P/E on the weakness of its forecast growth being lower than the wider market, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. It's hard to see the share price rising strongly in the near future under these circumstances.
