FYI: For those who've grown used to a decade in which mining and energy companies bestrode the world, the current malaise in commodities markets can feel like the end times. At the start of 2011, 14 out of 53 companies with market values above $100 billion were in the oil and mining sectors. That club has since expanded to 69 corporates, but only Exxon Mobil, PetroChina, Chevron, Shell and Total are still members.
