Commonwealth Bank shares (ASX: CBA): record profit, a valuation puzzle, and what investors are watching in 2026

Daniel Nguyen Jul 18, 2026 · 4 min read

The short version: CBA posted a record $5.45 billion cash profit for the first half of FY2026 — up 6% year-on-year — and shares jumped 7% on results day. The stock is now trading near AU$170.93. The question most investors are sitting with is not whether the business is performing well (it clearly is), but whether the current share price already prices in everything good that could happen.

Where CBA shares are trading now

Commonwealth Bank of Australia (ASX: CBA) is trading at AU$170.93 as of July 16, 2026

That price puts CBA among the most expensive bank stocks in the developed world on a price-to-earnings basis. For context, CBA's one-year total shareholder return through early February 2026 was just 1.11% — not because the business was struggling, but because much of the good news had already been priced in.

2026 has seen a significant move higher, fuelled almost entirely by the February half-year result.

What the H1 FY2026 results showed

CBA released its half-year results on February 11, 2026, for the six months ended December 31, 2025. The headline numbers were strong across the board:

Cash profit: $5.45 billion — a record for any Australian bank in a single half-year reporting period
Up 6% on the prior corresponding period
Business lending growth: CBA grew its business lending book during the period, outpacing system credit growth
Market share gains: Morningstar noted CBA was "taking share in a competitive market" during the period, per its February 12 analysis

CEO Matt Comyn described the result in a statement on the CommBank newsroom: "We have continued to execute our strategy with discipline, maintaining a strong focus on operating performance."

The $5.45 billion figure blitzed market expectations, according to SMH, which noted analysts had expected a lower result heading into the release.

How the market reacted

CBA shares surged 7% on results day, February 11 dragging the broader ASX 200 higher along with it. The reaction reflected genuine surprise at the scale of the beat — the $5.45 billion number was not just above consensus, it was a record.

The ASX 200 rallied on the day, with the CBA move acting as a significant index contributor given its market cap weighting

The valuation debate

Here is where it gets genuinely interesting.

Despite the record profit and the 7% single-day rally, Morningstar maintained that CBA "remains overvalued despite the strong result," per its February 12, 2026 analysis. Morningstar's fair value estimate for CBA stood at $100 per share as of late January 2026, per its earnings season preview — a level the stock traded significantly above even before the February surge.

AFR put it bluntly in January, writing that CBA "faces an uphill battle to win back investors in 2026," per its January 13 report — noting that the bank's share price had already priced in considerable optimism.

The tension is real: the underlying business is genuinely strong, growing market share and posting record profits. At the same time, the stock's price-to-earnings multiple is extreme by any historical standard for a bank. These two things can both be true simultaneously, and that's what makes CBA one of the more debated stocks on the ASX.

What the RBA rate environment means for CBA

Interest rates are central to how CBA earns money. Higher rates, in theory, widen net interest margins — the gap between what banks charge on loans and what they pay on deposits. CEO Matt Comyn flagged "upward pressure on rates" in commentary around the results.

The RBA held interest rates steady at its June 2026 meeting, per social reporting from May 2026, keeping the cash rate environment relatively stable. Any future rate changes — either up or down — will directly affect CBA's net interest margin and, by extension, its profitability.

For mortgage holders, the rate environment stays a concern. The Yahoo Finance headline on results day captured the contrast plainly: "CBA's $5.4bn bonanza amid mortgage hell" — a title that reflects just how divided the experience of high rates is between the bank and its borrowers

Key things to watch in the second half of 2026

Three things worth tracking for CBA shareholders and observers over the rest of the year:

Full-year results (August 2026). CBA's full-year results for FY2026 — covering the 12 months to June 30, 2026 — will be the next major event. Given the record H1 result, market expectations will be elevated. The question is whether the second half maintained momentum, particularly given competition in mortgage and business lending markets.

Final dividend announcement. CBA typically announces its full-year dividend alongside the August result. Following a strong H1, income investors will watch whether the full-year payout improves materially on prior years.

RBA policy direction. Any signal from the Reserve Bank about the rate path — particularly any cut to the cash rate — would affect margin expectations and, consequently, analyst earnings forecasts for CBA. Rate cuts compress margins; rate rises expand them, up to a point.
