With a price-to-earnings (or "P/E") ratio of 20.6x Marten Transport, Ltd. (NASDAQ:MRTN) may be sending bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 17x and even P/E's lower than 9x are not unusual. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.
With earnings that are retreating more than the market's of late, Marten Transport has been very sluggish. It might be that many expect the dismal earnings performance to recover substantially, which has kept the P/E from collapsing. If not, then existing shareholders may be very nervous about the viability of the share price.
What Are Growth Metrics Telling Us About The High P/E?
There's an inherent assumption that a company should outperform the market for P/E ratios like Marten Transport's to be considered reasonable.
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 36%. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.
Turning to the outlook, the next year should generate growth of 0.5% as estimated by the sole analyst watching the company. That's shaping up to be materially lower than the 11% growth forecast for the broader market.
With this information, we find it concerning that Marten Transport is trading at a P/E higher than the market. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.
The Key Takeaway
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.
We've established that Marten Transport currently trades on a much higher than expected P/E since its forecast growth is lower than the wider market. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings aren't likely to support such positive sentiment for long. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
