NetApp, Inc.'s (NASDAQ:NTAP) price-to-earnings (or "P/E") ratio of 23.2x might make it look like a sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 17x and even P/E's below 9x 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 as high as it is.

NetApp has been struggling lately as its earnings have declined faster than most other companies. 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.

Is There Enough Growth For NetApp?

In order to justify its P/E ratio, NetApp would need to produce impressive growth in excess of the market.

Retrospectively, the last year delivered a frustrating 24% decrease to the company's bottom line. Even so, admirably EPS has lifted 71% in aggregate from three years ago, notwithstanding the last 12 months. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Looking ahead now, EPS is anticipated to climb by 9.0% during the coming year according to the analysts following the company. Meanwhile, the rest of the market is forecast to expand by 11%, which is noticeably more attractive.

With this information, we find it concerning that NetApp 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. There's a good chance these shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

The Bottom Line On NetApp's P/E

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.

Our examination of NetApp's analyst forecasts revealed that its inferior earnings outlook isn't impacting its high P/E anywhere near 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 high P/E lower. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
