Money of Mine Rob Mullin: Gold Stocks Still Cheap, Energy Stocks Cheaper
We continue our search for the world’s best natural-resource investors with today’s guest, Rob Mullin.
Rob is the Founder and CIO of Marathon Resource Advisors, a long-short fund that has compounded at extraordinary rates by doing what few others still do: buying real cash flow, not stories.
In this wide-ranging chat, Rob explains why gold stocks remain “super cheap” despite their strong run, why he’s finding his best ideas in overlooked European energy producers, and how he frames risk through volatility rather than avoiding it.
We dig into the structural forces reshaping the market, from the dominance of pod shops and passive flows to the slow return of generalist investors to resources. Rob also lays out why he believes tangible assets are set to outperform financial abstractions for years to come.
Along the way, he contrasts the speculative vibe economy of AI and crypto with the grounded reality of mining and energy cash flows, and why this cycle could belong to the real economy again.
