Ann: Quarterly Report - March 2018, page-150

RIO doesn't have an upcoming operation that could increase company earnings by several hundred percent.

Big difference.

It's all about future value - if I invest now, what is my risked return in x months/years?
FCF today means diddly squat to those here for the upcoming company-multiplying expansions.

Best of luck with your $2 target. If it gets pushed there (which it certainly could), the trucks will be backing up; mine included.
