Nova Ltd. (NASDAQ:NVMI) shares have had a really impressive month, gaining 29% after a shaky period beforehand. Looking back a bit further, it's encouraging to see the stock is up 75% in the last year.

After such a large jump in price, Nova may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 42.2x, since almost half of all companies in the United States have P/E ratios under 18x and even P/E's lower than 10x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Nova has been doing quite well of late. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Nova's Growth Trending?

Nova'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, we see that the company managed to grow earnings per share by a handy 12% last year. The latest three year period has also seen an excellent 119% overall rise in EPS, aided somewhat by its short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.

Looking ahead now, EPS is anticipated to climb by 13% each year during the coming three years according to the six analysts following the company. With the market only predicted to deliver 10% per year, the company is positioned for a stronger earnings result.

With this information, we can see why Nova is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Key Takeaway

The strong share price surge has got Nova's P/E rushing to great heights as well. 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.

We've established that Nova maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. Right now shareholders are comfortable with the P/E as they are quite confident future earnings aren't under threat. It's hard to see the share price falling strongly in the near future under these circumstances.
