Sumitomo Metal Mining (TSE:5713): Valuation Check After Leading Japanese Market Gains on Global Optimism

Listen to the news

Sumitomo Metal Mining (TSE:5713) jumped 9% on Friday as Asian markets rallied on upbeat Wall Street trading and fresh expectations of China stimulus, putting this materials heavyweight back on many investors watchlists.

See our latest analysis for Sumitomo Metal Mining.

That one day surge caps a powerful run, with a 30 day share price return of 16.25% and a 90 day gain of 37.43%. The 1 year total shareholder return of 67.38% signals momentum is still building rather than fading.

If this rally has you rethinking where the next cyclical winner could emerge, it might be worth scanning fast growing stocks with high insider ownership for other under the radar names showing strong momentum and insider conviction.

Yet with the shares now trading above consensus targets after a huge 12 month run, investors must decide whether Sumitomo Metal Mining is still mispriced relative to its long term cycle, or if the market is already discounting future growth.

Price-to-Earnings of 67.3x: Is it justified?

Based on a lofty price-to-earnings ratio of 67.3x versus the last close of ¥5952, the market is clearly pricing in elevated expectations for Sumitomo Metal Mining.

The price-to-earnings multiple compares the current share price to the company’s earnings, making it a direct gauge of how much investors are willing to pay for each unit of profit in this cyclical metals and mining business.

Sumitomo Metal Mining is currently considered expensive on this metric, trading at 67.3x earnings compared to an estimated fair price-to-earnings ratio of 20.7x. This is a level the market could ultimately gravitate toward if optimism cools.

The gap is even starker when stacked against benchmarks. The stock’s 67.3x price-to-earnings multiple towers over the 12.1x average for the JP metals and mining industry and the 23.6x peer average, underscoring how aggressively the market is rewarding its earnings relative to rivals.
