SI386: When Position Sizing Saves You ft. Rob Carver

Today, we are joined by Rob Carver to unpack one of the most volatile weeks seen in commodity markets in years. The conversation centers on silver’s sharp rise and sudden collapse, using it as a case study in volatility targeting, liquidity risk, and disciplined position sizing. From Freaky Friday to broader dislocations across assets, they examine why systematic risk management matters when markets move faster than narratives. The discussion expands into diversification, correlation assumptions, alternative markets, and new research on trend portfolio construction, offering a grounded reminder that survival often matters more than precision.
