A Sliding Share Price Has Us Looking At BWX Technologies, Inc.'s (NYSE:BWXT) P/E Ratio

Simply Wall St

To the annoyance of some shareholders, BWX Technologies (NYSE:BWXT) shares are down a considerable 31% in the last month. Even longer term holders have taken a real hit with the stock declining 3.8% in the last year.

Assuming nothing else has changed, a lower share price makes a stock more attractive to potential buyers. While the market sentiment towards a stock is very changeable, in the long run, the share price will tend to move in the same direction as earnings per share. The implication here is that long term investors have an opportunity when expectations of a company are too low. Perhaps the simplest way to get a read on investors' expectations of a business is to look at its Price to Earnings Ratio (PE Ratio). Investors have optimistic expectations of companies with higher P/E ratios, compared to companies with lower P/E ratios.

That means that the market expects BWX Technologies will outperform other companies in its industry. Shareholders are clearly optimistic, but the future is always uncertain. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. When earnings grow, the 'E' increases, over time. And in that case, the P/E ratio itself will drop rather quickly. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

It's great to see that BWX Technologies grew EPS by 12% in the last year. And earnings per share have improved by 49% annually, over the last five years. So one might expect an above average P/E ratio.

A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. So it won't reflect the advantage of cash, or disadvantage of debt. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

BWX Technologies's Balance Sheet

BWX Technologies's net debt is 16% of its market cap. That's enough debt to impact the P/E ratio a little; so keep it in mind if you're comparing it to companies without debt.

The Bottom Line On BWX Technologies's P/E Ratio

BWX Technologies's P/E is 18.6 which is above average (12.8) in its market. While the company does use modest debt, its recent earnings growth is very good. Therefore, it's not particularly surprising that it has a above average P/E ratio. Given BWX Technologies's P/E ratio has declined from 26.8 to 18.6 in the last month, we know for sure that the market is significantly less confident about the business today, than it was back then. For those who prefer to invest with the flow of momentum, that might be a bad sign, but for a contrarian, it may signal opportunity.

Investors have an opportunity when market expectations about a stock are wrong. If the reality for a company is better than it expects, you can make money by buying and holding for the long term. So this free visual report on analyst forecasts could hold the key to an excellent investment decision.
