Aviat Networks, Inc. (NASDAQ:AVNW) shareholders have seen the share price descend 20% over the month. But that doesn't undermine the fantastic longer term performance (measured over five years). In that time, the share price has soared some 382% higher! So we don't think the recent decline in the share price means its story is a sad one. Only time will tell if there is still too much optimism currently reflected in the share price. Unfortunately not all shareholders will have held it for the long term, so spare a thought for those caught in the 48% decline over the last twelve months.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Aviat Networks' earnings per share are down 25% per year, despite strong share price performance over five years. The impact of extraordinary items on earnings, in the last year, partially explain the diversion.

Essentially, it doesn't seem likely that investors are focused on EPS. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

In contrast revenue growth of 12% per year is probably viewed as evidence that Aviat Networks is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive growth.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money. This free report showing analyst forecasts should help you form a view on Aviat Networks

A Different Perspective

Aviat Networks shareholders are down 48% for the year, but the market itself is up 8.2%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 37% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
