  • How to Value National Australia Bank (NAB) Shares Using P/E Ratio
    May 29, 2026, 10:18 PM EDT. National Australia Bank Ltd (ASX: NAB) trades around $37, attracting yield-focused investors. A key valuation tool is the price-earnings (P/E) ratio, which compares share price to yearly earnings per share. NAB's P/E ratio stands at 16.5x based on a $37.33 share price and $2.26 earnings per share (EPS). This is below the banking sector average of 18x. Applying the sector average P/E to NAB's EPS suggests a fair value of about $40.72, hinting NAB shares might be undervalued compared to peers. The P/E ratio provides a useful benchmark but should be combined with other analysis methods for robust investment decisions.
