Minimum, maximum, median and geometric mean only use the families both stocks have (matching families: 8 of 8), so a family without a value on one side does not distort the comparison. Ahead in a family is the stock whose fair value there sits higher relative to its price. Geometric because deviations are ratios: half the price and twice the price average to 100%, not 125%.
Family by family: Costco is ahead in 4 of 8 shared families, Walmart in 4.
Costco: 26 of 26 models see the stock below the current price.
Walmart: 26 of 26 models see the stock below the current price.
