Using comps for PE ratios
The ‘PE’ ratio compares a company’s share price (P) to its most recent full-year earnings per share (E). Remember, ‘earnings’ is just another word for profit. That means, the PE ratio is simply comparing share price to the most recent yearly profit of the company. Some experts will try to tell you that ‘the lower PE ratio is better’ because it means the share price is ‘low’ relative to the profits produced by the company. However, sometimes shares are cheap for a reason!
Secondly, some extremely successful companies have gone for many years (a decade or more) and never reported an accounting profit — so the PE ratio can’t be used to value them.
Therefore, we think it’s crucial to dig deeper than just looking at the PE ratio and thinking to yourself ‘if it’s below 10x, I’ll buy it.’
One of the easy ratio models analysts use to value a bank share is to compare the PE ratio of the bank/share you’re looking at with its peer group or competitors and try to determine if the share is too much or cheap relative to the average. From there, and using the principle of mean reversion, we can multiply the profits/earnings per share by the sector average (E x sector PE) to reflect what an average company would be worth. It’s like saying, ‘if all of the other stocks are priced at ‘X’, this one should be too’.
If we take the NAB share price today ($37.96), 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 16.5x. That compares to the banking sector average PE of 16x.
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 $37.01.
Why fully franked dividends boost the NAB share price
Given that ASX bank shares like NAB tend to have a history of paying dividends — and they are relatively stable businesses like REITs — we can use a modelling tool called a dividend discount model or DDM to do a valuation.
A DDM uses the dividends shareholders are ‘expected’ to receive to arrive at a valuation. To do this you’ll need to know the last full-year dividend, and make an assumption and what you think the dividend growth will look like for the next few years. The only other number you need is a ‘risk’ rate (e.g. 7%) which is explained further below.
To do the valuation, use this formula: Share price = full-year dividend / (risk rate – dividend growth rate). It’s a good idea to do the calculation with a few different growth and risk assumptions, then take the average valuation. This helps to account for some of the uncertainty.
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 $35.31. However, using an ‘adjusted’ dividend payment of $1.68 per share, the valuation goes to $30.11. The expected dividend valuation compares to National Australia Bank Ltd’s share price of $37.96. 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 ($2.40), our valuation of the NAB share price prediction to $43.02.
