Story Continues

What counts as a “normal” P/E depends on what the market expects from a company. Higher expected growth or lower perceived risk can support a higher P/E, while lower expected growth or higher risk usually means a lower P/E looks more reasonable.

South32 currently trades on a P/E of 37.19x. That sits above the Metals and Mining industry average of 13.31x and the peer group average of 25.75x. Simply Wall St’s Fair Ratio for South32 is 26.21x, which is its proprietary view of what a “fair” P/E could be after weighing factors such as earnings growth, industry, profit margins, market cap and company specific risks.

This Fair Ratio can be more useful than simple peer or industry comparisons because it adjusts for the specific characteristics of South32 rather than assuming all miners deserve similar multiples. With the current P/E of 37.19x compared to a Fair Ratio of 26.21x, the shares appear expensive on this measure.
