When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 16x, you may consider Camtek Ltd. (NASDAQ:CAMT) as a stock to avoid entirely with its 45.4x P/E ratio. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Recent times have been pleasing for Camtek as its earnings have risen in spite of the market's earnings going into reverse. 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. If not, then existing shareholders might be a little nervous about the viability of the share price.

Does Growth Match The High P/E?

Camtek'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.

Retrospectively, the last year delivered a decent 13% gain to the company's bottom line. Pleasingly, EPS has also lifted 268% in aggregate from three years ago, partly thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Turning to the outlook, the next year should generate growth of 7.9% as estimated by the six analysts watching the company. Meanwhile, the rest of the market is forecast to expand by 13%, which is noticeably more attractive.

In light of this, it's alarming that Camtek's P/E sits above the majority of other companies. 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 Key Takeaway

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that Camtek currently trades on a much higher than expected P/E since its forecast growth is lower than the wider market. 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. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.

Many other vital risk factors can be found on the company's balance sheet. Take a look at our free balance sheet analysis for Camtek with six simple checks on some of these key factors.
