Our largest bank shares make up more than one-third of the local share market, measured by the market capitalisation of the largest 200 companies in the S&P/ASX 200 index.

A proper PE ratio for NAB shares
The PE ratio compares a company’s share price (P) to its yearly earnings per share (E) (note: ‘earnings’ is another word for profit).
There are three simple ways to quickly use the PE ratio. First, you can use ‘intuition’ and say ‘if it’s low, I’ll buy shares’ or ‘if it is above 40x, I’ll sell shares’ (whatever works for you).
Secondly, you can compare the PE ratio of a stock like NAB with ANZ or the sector average. Is it higher or lower? Does it deserve to be more expensive or cheaper? Third, you can take the earnings/profits per share of the company you’re valuing and multiply that number by a PE multiple that you believe is appropriate. For example, if a company’s profit per share (E) was $5 and you believe the stock is ‘worth at least 10x its profit’ it would have a valuation, according to you, of $5 x 10 = $50 per share.
If we take the NAB share price today ($29.08), together with the earnings (aka profits) per share data from its 2023 financial year ($2.3), we can calculate the company’s PE ratio to be 12.6x. That compares to the banking sector average PE of 13x.
Next, take the profits per share (EPS) ($2.3) and multiply it by the average PE ratio for NAB’s sector (Banking). This results in a ‘sector-adjusted’ PE valuation of $28.80.
NAB share price analysis
A dividend discount model or ‘DDM’ is a more robust way of valuing companies in the banking sector.
DDM valuation models are some of the oldest proper valuation models used by professional analysts or brokers on Wall Street (note: just because they’re old doesn’t make them ‘good’). A DDM model takes the most recent full year dividends (e.g. from last 12 months or LTM), or forecast dividends for next year, and then assumes the dividends remain consistent or grow for the forecast period.
To make this DDM easy to understand, we will assume last year’s dividend payment ($1.67) rises at a fixed rate each year.
Next, we pick the ‘risk’ rate or expected return rate. This is the rate at which we discount the future dividend payments back to today’s dollars. The higher the ‘risk’ rate, the lower the share price valuation.
We’ve used a blended rate for dividend growth and a risk rate between 6% and 11%, then got the average.
This simple DDM valuation of NAB shares is $31.84. However, using an ‘adjusted’ dividend payment of $1.71 per share, the valuation goes to $30.65. The expected dividend valuation compares to National Australia Bank Ltd’s share price of $29.08. Since the company’s dividends are fully franked, you might choose to make one further adjustment and do the valuation based on a ‘gross’ dividend payment. That is, the cash dividends plus the franking credits (available to eligible shareholders). Using the forecast gross dividend payment ($2.44), our valuation of the NAB share price calculation to $43.79.
NAB share price: don’t stop with this
Our two models could be used as an introductory guide for how the valuation process works. Analysing a bank share like National Australia Bank Ltd is a complicated task. If we were looking at the shares and considering an investment, we would first want to know more about the bank’s growth strategy. For example, are they pursuing more lending (i.e. interest income) or more non-interest income (fees from financial advice, investment management, etc..
Next, take a close look at economic indicators like unemployment, house prices and consumer sentiment. Where are they headed? Finally, we believe it’s important to make an assessment of the management team. For example, when we pulled data on NAB’s culture we found that it wasn’t a perfect 5/5. Culture is one thing to think carefully about.
