Most Popular Narrative: 8% Undervalued

The most followed narrative places National Australia Bank's fair value at A$41.53, slightly above the last close at A$38.36. This frames the current pullback as modest relative to that estimate.

Ongoing digital transformation, focus on cost management, and productivity initiatives (including Citi integration, streamlined processes, and leveraging AI tools) are expected to structurally reduce the cost-to-income ratio over time, potentially boosting net margins and profitability.

Another View: Valuation Through the P/E Lens

That 8% undervaluation story sits beside a very different message from the P/E ratio. NAB trades on 19.2x earnings, above the global banks average of 11x and slightly above peers at 19x, while the fair ratio is 21.4x. Is this a margin of safety, or a valuation tightrope for you?
