Gogo Inc. (NASDAQ:GOGO) shareholders would be excited to see that the share price has had a great month, posting a 34% gain and recovering from prior weakness. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 15% over that time.

Although its price has surged higher, it's still not a stretch to say that Gogo's price-to-earnings (or "P/E") ratio of 19.2x right now seems quite "middle-of-the-road" compared to the market in the United States, where the median P/E ratio is around 18x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

Gogo could be doing better as its earnings have been going backwards lately while most other companies have been seeing positive earnings growth. One possibility is that the P/E is moderate because investors think this poor earnings performance will turn around. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

In order to justify its P/E ratio, Gogo would need to produce growth that's similar to the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 64%. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Turning to the outlook, the next year should generate growth of 5.8% as estimated by the five analysts watching the company. With the market predicted to deliver 15% growth , the company is positioned for a weaker earnings result.

In light of this, it's curious that Gogo's P/E sits in line with the majority of other companies. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. These shareholders may be setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

The Key Takeaway

Gogo's stock has a lot of momentum behind it lately, which has brought its P/E level with the market. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of Gogo's analyst forecasts revealed that its inferior earnings outlook isn't impacting its P/E as much as we would have predicted. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.

It is also worth noting that we have found 3 warning signs for Gogo (1 doesn't sit too well with us!) that you need to take into consideration.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
