May 23, 2026, 11:29 PM EDT. Westpac Banking Corp (WBC) shares trade around $36.55 on the ASX, holding a price-earnings (PE) ratio of 19x versus the banking sector average of 18x. The PE ratio, which compares share price to annual earnings per share ($1.92 for WBC), serves as a basic valuation tool but may overlook dividends crucial for mature banks. Investors should consider the Dividend Discount Model (DDM), valuing shares based on projected dividends and their growth, discounted by a risk rate (e.g., 7%). The DDM provides a more robust valuation, reflecting the consistent dividends typical of banking stocks. Employing both methods offers a balanced view of WBC's market value amid ASX's dominant bank sector.
