How the comparison is scored
QuantLink marks a row leader only when both companies have a numeric value and the metric has a fixed comparison direction. Lower values lead on valuation multiples and debt/equity, while higher values lead on profitability and dividend yield.
Price and market capitalization are shown for context only, so they do not receive a leader checkmark and do not affect the tally.
