How Do You Calculate A P/E Ratio?

The formula for P/E is:

Price to Earnings Ratio = Share Price (in reporting currency) ÷ Earnings per Share (EPS)

Or for Alumina:

P/E of 7.61 = $1.68 (Note: this is the share price in the reporting currency, namely, USD ) ÷ $0.22 (Based on the trailing twelve months to December 2018.)

Is A High Price-to-Earnings Ratio Good?

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. 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

P/E ratios primarily reflect market expectations around earnings growth rates. When earnings grow, the 'E' increases, over time. That means even if the current P/E is high, it will reduce over time if the share price stays flat. Then, a lower P/E should attract more buyers, pushing the share price up.

Alumina's earnings made like a rocket, taking off 87% last year. The sweetener is that the annual five year growth rate of 314% is also impressive. So I'd be surprised if the P/E ratio was not above average.

How Does Alumina's P/E Ratio Compare To Its Peers?

We can get an indication of market expectations by looking at the P/E ratio. The image below shows that Alumina has a lower P/E than the average (11.9) P/E for companies in the metals and mining industry.

ASX:AWC Price Estimation Relative to Market, May 27th 2019

Alumina's P/E tells us that market participants think it will not fare as well as its peers in the same industry. Since the market seems unimpressed with Alumina, it's quite possible it could surprise on the upside. You should delve deeper. I like to check if company insiders have been buying or selling.

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

The 'Price' in P/E reflects the market capitalization of the company. That means it doesn't take debt or cash into account. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

Alumina's Balance Sheet

The extra options and safety that comes with Alumina's US$77m net cash position means that it deserves a higher P/E than it would if it had a lot of net debt.

The Verdict On Alumina's P/E Ratio

Alumina trades on a P/E ratio of 7.6, which is below the AU market average of 16.2. It grew its EPS nicely over the last year, and the healthy balance sheet implies there is more potential for growth. The below average P/E ratio suggests that market participants don't believe the strong growth will continue.

Investors have an opportunity when market expectations about a stock are wrong. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
