With a price-to-earnings (or "P/E") ratio of 34.9x Lam Research Corporation (NASDAQ:LRCX) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 16x and even P/E's lower than 9x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Recent times haven't been advantageous for Lam Research as its earnings have been falling quicker than most other companies. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Keen to find out how analysts think Lam Research's future stacks up against the industry? In that case, our free report is a great place to start.

Does Growth Match The High P/E?

Lam Research's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better 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 24%. That put a dampener on the good run it was having over the longer-term as its three-year EPS growth is still a noteworthy 15% in total. Accordingly, while they would have preferred to keep the run going, shareholders would be roughly satisfied with the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 22% per year during the coming three years according to the analysts following the company. With the market only predicted to deliver 9.9% per year, the company is positioned for a stronger earnings result.

In light of this, it's understandable that Lam Research's P/E sits above the majority of other companies. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.
