Peer comparison in the stock market refers to the fundamental analytical process of evaluating a specific public corporation's financial performance, valuation multiples, operational efficiency, and growth metrics against those of its closest direct competitors operating within the exact same industry sector. By contrasting financial ratios such as price-to-earnings, debt-to-equity, profit margins, and return on equity with industry peers, institutional and retail investors can better determine whether a particular stock is overvalued, undervalued, or positioned strongly relative to its market competition.
