SLM Corporation's (NASDAQ:SLM) Shares Not Telling The Full Story

SLM Corporation's (NASDAQ:SLM) price-to-earnings (or "P/E") ratio of 11.6x 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 19x and even P/E's above 34x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

SLM hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It seems that many are expecting the dour earnings performance to persist, which has repressed the P/E. If you still 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.

What Are Growth Metrics Telling Us About The Low P/E?

SLM's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 13%. Still, the latest three year period has seen an excellent 32% overall rise in EPS, in spite of its unsatisfying short-term performance. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Turning to the outlook, the next three years should generate growth of 11% per annum as estimated by the eight analysts watching the company. Meanwhile, the rest of the market is forecast to expand by 10% per year, which is not materially different.

With this information, we find it odd that SLM is trading at a P/E lower than the market. It may be that most investors are not convinced the company can achieve future growth expectations.

The Key Takeaway

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that SLM currently trades on a lower than expected P/E since its forecast growth is in line with the wider market. There could be some unobserved threats to earnings preventing the P/E ratio from matching the outlook. At least the risk of a price drop looks to be subdued, but investors seem to think future earnings could see some volatility.
