The Big 4 Fracturing? Whether experts issuing a "Sell Alert" on CBA Shares justified?

The art of Great Investing is not just about owning high-quality businesses but also about paying the right price, as even great companies can deliver very poor returns when bought at excessive valuations.

This seems to be the position Commonwealth Bank of Australia (ASX: CBA) is in today, where strong fundamentals are being overshadowed by a stretched valuation.

Commonwealth Bank of Australia (ASX: CBA) 

is the highest quality banking franchise in the country but recent analysis has suggested that its valuation may now be stretched relative to fundamentals and current market capitalisation is $289.38 billion.

Strong operations and financial performance

The bank in 1H26 reported cash net profit after tax of $5.445 billion which was up 6% year-on-year due to disciplined growth and consistent execution.
Operating income reached $15 billion which was an increase of 6.6% because of solid lending and deposit growth while margins were stable in a competitive environment.

Its strong franchise is clear from its dominant market position which is supported by deep customer relationships. Customer engagement also stands out with more than 9.4 million active app users and about 14 million daily logins which supports its leadership in digital banking.

The balance sheet is among the strongest with a CET1 capital ratio of 12.3% which is well above regulatory requirements and deposit funding at 79% of total funding.
Credit quality is strong as loan impairment expenses are low which reflects management's cautious risk management.

The bank also declared an interim dividend of $2.35 per share which is 10 cents higher than the previous corresponding period.

Growth outlook is stable

Operational performance is very strong but the outlook points to more moderate growth ahead. Credit growth is expected to stay steady because the broader economy will normalise and household debt levels will stabilise.

Net interest margins which are a key driver of profitability are likely to remain stable due to competition and pressure from funding costs.

The bank has invested heavily in technology, AI and customer experience which will support long-term growth but can increase near term costs. These investments strengthen the franchise but they do not immediately lead to higher earnings growth.

As a result, earnings momentum should remain solid but not strong enough to justify very high valuation premiums.

Valuation concerns

The stock is trading at a price/earnings multiple of around 28 which is much higher than other 3 big Australian banks that trade in the high-teens multiples despite similar earnings growth prospects.
This premium shows that the market has already priced in a large part of future growth which leaves limited upside potential.

The current annual dividend yield is around 2.86% which is lower than peers and less attractive for income focused investors.

Most of the positive factors are already reflected in the stock price and any slowdown in growth could create downside risk.

Final thoughts

Commonwealth Bank of Australia is a best-in-class banking franchise with exceptional financials and high returns on capital. However, a premium valuation has reduced future returns prospects for shareholders.
