- Two popular methods to evaluate bank shares

- Key factors to monitor beyond basic metrics
National Australia Bank Ltd (ASX:NAB) is part of the ASX 100 stocks, a group that includes some of Australia’s most well-known companies. Understanding how to assess the value of such shares can help investors make informed decisions based on objective analysis rather than market noise. This article explains two widely used valuation methods for ASX bank shares and outlines important factors to consider beyond the numbers.
PE Ratio: Comparing Price to Earnings
The price-to-earnings (P/E) ratio measures how a company’s share price compares to its earnings. For NAB, this involves taking the current share price and dividing it by the earnings per share from the most recent financial year.
Analysts often compare a bank’s P/E ratio to the sector average. If NAB’s ratio is below the average, it may suggest the market is valuing it lower relative to its peers. However, context matters — differences in growth prospects, risk exposure, and operational performance can all influence these numbers.
One approach is to use the sector’s average P/E and multiply it by NAB’s earnings per share to estimate a sector-adjusted valuation. This technique assumes that similar companies should trade at comparable multiples, but it should always be combined with further research.
Dividend Discount Model (DDM)
The DDM takes a different path by focusing on future dividend payments. This method estimates value by forecasting dividend growth and applying a “discount rate” to reflect the risk of receiving those payments.
Because banks like NAB have a long history of stable dividend distributions, this model can be particularly relevant. Using past dividend figures, an analyst can project growth over time and calculate a present value. Adjustments can also be made for franking credits, which are a unique feature of the Australian market.
Looking Beyond the Models
While these models are helpful, they should not be used in isolation. Reviewing NAB’s loan growth, provisions for bad debts, and capital sources can provide deeper insight into its risk profile and operational strength. For example, a high reliance on wholesale debt markets may introduce different risks compared to funding primarily from customer deposits.
