No one can tell you for certain whether now is the perfect time to buy.
In the short run, the share market can seem like a random place. It can be up 2% one day, down 3% the next. There’s often no rhyme or reason (although pundits are paid the big bucks for the evening news to make you think they have a crystal ball).
In this article, we’ll go step-by-step through two basic valuation tools you can use to value a share like WBC or even Bank of Queensland Limited (ASX: BOQ) and National Australia Bank Ltd (ASX: NAB).
PE ratios: how to use it to value the WBC share price
It’s likely that if you have been actively investing in shares for more than a few years you will have heard about the PE ratio. The price-earnings ratio or ‘PER’ compares a company’s share price (P) to its most recent full-year earnings per share (E). If you bought a coffee shop for $100,000 and it made $10,000 of profit last year, that’s a price-earnings ratio of 10x ($100,000 / $10,000). ‘Earnings’ is just another word for profit. So, the PE ratio is basically saying ‘price-to-yearly-profit multiple’.
The PE ratio is a very general tool but it’s not perfect so it’s vital to use it with other techniques (see below) to back it up. That said, one of the rough ratio strategies even professional analysts will use to value a share is to compare the company’s PE ratio with its competitors to try to determine if the share price is overvalued or cheap. It’s akin to saying: ‘if all of the other banking sector stocks are priced at a PE of X, this one should be too’. We’ll go one step further than that in this article. We’ll apply the principle of mean reversion and multiply the profits per share (E) by the sector average PE ratio (E x sector PE) to calculate what an average company would be worth.
If we take the WBC share price today ($30.23), together with the earnings (aka profits) per share data from its 2023 financial year ($1.95), we can calculate the company’s PE ratio to be 15.5x. That compares to the banking sector average PE of 16x.
Next, take the profits per share (EPS) ($1.95) and multiply it by the average PE ratio for WBC’s sector (Banking). This results in a ‘sector-adjusted’ PE valuation of $31.21.
How we’d value WBC shares
A dividend discount model or DDM is a much more robust way of valuing companies in the banking sector — if it’s done correctly (take your time!).
DDM valuation models are some of the oldest valuation models used on Wall Street and even here in Australia. A DDM model uses 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 slightly for the forecast period (e.g. 5 years or forever). 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 ($1.42) goes up 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 WBC shares is $27.07. However, using an ‘adjusted’ dividend payment of $1.68 per share, the valuation goes to $30.11. The expected dividend valuation compares to Westpac Banking Corp’s share price of $30.23. 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 WBC share price estimate to $43.02.
Where to from here
Make sure you don’t forget that the two models used here are only the starting point of the process for analysing and valuing a bank share like WBC.
We think it’s good practice to read at least three years of annual reports, jot down your thoughts/research and set out your thesis/expectations based on what management is saying. Indeed, a very useful tool is studying management’s language in presentations and videos. Is the management team candid? Or does he/she use lots of jargon and never answer a straight question? Finally, read articles and research from good analysts, and when you do, seek out people who disagree with you. These voices are often the most helpful.
These are just a handful of the best strategies to use alongside your valuation tools to determine if you’re making a mistake — hopefully, before you make a costly mistake!
