How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)

Or for Amkor Technology:

P/E of 18.03 = $7.13 ÷ $0.40 (Based on the year to March 2019.)

Is A High P/E Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each $1 the company has earned over the last year. That isn’t necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. That’s because companies that grow earnings per share quickly will rapidly increase the ‘E’ in the equation. 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.

Amkor Technology shrunk earnings per share by 67% over the last year. But it has grown its earnings per share by 58% per year over the last three years. And it has shrunk its earnings per share by 7.1% per year over the last five years. This might lead to muted expectations.

Amkor Technology’s P/E tells us that market participants think it will not fare as well as its peers in the same industry. Many investors like to buy stocks when the market is pessimistic about their prospects. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.

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

Don’t forget that the P/E ratio considers market capitalization. Thus, the metric does not reflect cash or debt held by the company. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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.

How Does Amkor Technology’s Debt Impact Its P/E Ratio?

Amkor Technology’s net debt equates to 50% of its market capitalization. You’d want to be aware of this fact, but it doesn’t bother us.

The Bottom Line On Amkor Technology’s P/E Ratio

Amkor Technology has a P/E of 18. That’s around the same as the average in the US market, which is 17.8. When you consider the lack of EPS growth last year (along with some debt), it seems the market is optimistic about the future for the business.
