What Is Apergy's (NYSE:APY) P/E Ratio After Its Share Price Rocketed?

Simply Wall St

It's great to see Apergy (NYSE:APY) shareholders have their patience rewarded with a 34% share price pop in the last month. The full year gain of 26% is pretty reasonable, too.

Assuming no other changes, a sharply higher share price makes a stock less attractive to potential buyers. In the long term, share prices tend to follow earnings per share, but in the short term prices bounce around in response to short term factors (which are not always obvious). The implication here is that deep value investors might steer clear when expectations of a company are too high. One way to gauge market expectations of a stock is to look at its Price to Earnings Ratio (PE Ratio). A high P/E ratio means that investors have a high expectation about future growth, while a low P/E ratio means they have low expectations about future growth.

NYSE:APY Price Estimation Relative to Market, December 30th 2019

Apergy's P/E tells us that market participants think the company will perform better than its industry peers, going forward. Shareholders are clearly optimistic, but the future is always uncertain. So further research is always essential. I often monitor director buying and selling.

How Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. When earnings grow, the 'E' increases, over time. And in that case, the P/E ratio itself will drop rather quickly. Then, a lower P/E should attract more buyers, pushing the share price up.

Apergy's earnings per share fell by 41% in the last twelve months. But EPS is up 8.9% over the last 5 years.

Remember: P/E Ratios Don't Consider The Balance Sheet

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

So What Does Apergy's Balance Sheet Tell Us?

Apergy has net debt worth 21% of its market capitalization. It would probably deserve a higher P/E ratio if it was net cash, since it would have more options for growth.

The Verdict On Apergy's P/E Ratio

Apergy trades on a P/E ratio of 33.5, which is above its market average of 18.9. With a bit of debt, but a lack of recent growth, it's safe to say the market is expecting improved profit performance from the company, in the next few years. What we know for sure is that investors have become much more excited about Apergy recently, since they have pushed its P/E ratio from 25.1 to 33.5 over the last month. If you like to buy stocks that have recently impressed the market, then this one might be a candidate; but if you prefer to invest when there is 'blood in the streets', then you may feel the opportunity has passed.
