Where CBA shares stand into Monday’s open
CBA closed A$157.30 on Friday, down about 10% from Monday’s A$174.92 close as the market punished the stock’s margin commentary despite headline profit growth. That weekly drawdown followed the 11 Nov update and leaves the shares well below their recent peak earlier this year.
For context on valuation, Reuters has repeatedly highlighted CBA’s premium multiples—with price-to-earnings and price‑to‑book more than double global bank averages—making the stock sensitive to any hint of slower margin momentum or cost pressure. Local market coverage last week framed much of the sell‑off as valuation‑led rotation to cheaper peers rather than a thesis change on CBA’s franchise quality.
What the latest quarterly update really said
CBA’s 1Q26 trading update (three months to 30 Sep 2025) showed:
- Cash NPAT: ~A$2.6bn (+1% vs 2H25 quarterly average, +2% YoY).
- Income: Operating income up 3%, with net interest income +3%; however, the headline NIM fell due to a mix‑shift into lower‑yielding liquid assets and institutional repos (plus deposit switching and competition).
- Volumes:Home loans +A$9.3bn (around 1.1x system); household deposits +A$17.8bn (about 1.2x system); ~175k increase in retail transaction accounts, largely from new‑to‑bank customers.
- Asset quality:Loan impairment expense A$220m (9 bps of GLAA); home‑loan arrears 0.66%, with consumer and corporate arrears improving as financial conditions eased.
- Funding & liquidity:Customer deposit funding ratio 79%, LCR 133%, NSFR 116%.
Margin disclosure: The bank did not publish a NIM figure, which irked some investors. Reuters reported the shares fell nearly 5% on the day as the market extrapolated downside for margins given deposit switching, competition and the lower cash‑rate environment.
Capital, dividends and regulatory backdrop
- CET1 (Level 2) stood at 11.8% on 30 Sep (well above APRA’s 10.25% minimum). Under the revised APS 117 for interest‑rate risk in the banking book (effective 1 Oct), CBA estimates a pro‑forma +20 bps boost to CET1 (~12.0%) from a lower IRRBB capital charge.
- The bank bought back >A$640m of shares on‑market in the quarter to neutralise DRP issuance (14.8% participation), signalling ongoing capital management discipline.
- For income investors, CBA paid a final FY25 dividend of A$2.60 (total FY25 A$4.85 per share). Using Friday’s close, the trailing yield is ~3.1% (A$4.85 / A$157.30).
Rates, housing and the week’s macro calendar
The RBA left the cash rate at 3.60% on 4 Nov and remains cautious given sticky inflation; minutes of that meeting publish on Tuesday, 18 Nov at 11:30 am AEDT. For bank shares, traders will parse any fresh colour on household balance sheets, deposit behaviour and the Board’s tolerance for prolonged “restrictive” settings. Reserve Bank of Australia+1
Separately, several lenders have nudged fixed mortgage rates higher in recent days, reflecting a modest shift in rate expectations—another cross‑current for bank margins as competitive pressures persist.
Why the stock fell last week despite a solid headline profit
Two themes explain the pullback:
- Margins in focus: Management flagged a slightly lower underlying NIM (ex‑liquidity mix) amid deposit switching and heavy competition, while declining to disclose the quarterly NIM. Markets often “shoot first” in premium‑multiple stocks when negative operating leverage is implied. announcements.asx.com.au+1
- Valuation premium: CBA’s status as one of the world’s most expensive major banks leaves the share price more sensitive to any deceleration in earnings momentum. Several commentators characterised the sell‑off as rotation into cheaper majors rather than a downgrade to CBA’s franchise strength.
Five things for ASX:CBA traders to watch at the open (Mon, 17 Nov)
- Opening auction & liquidity: Be mindful of the OSPA—the open is randomised around 9:59 am, with continuous trading starting 9:59:45–10:00:00. Gaps are common on news‑heavy days; pre‑open order depth can be thin.
- Follow‑through on U.S. lead: A mixed Wall St close Friday (Dow down, Nasdaq slightly up) offers a neutral cue; look for local risk appetite across the bank complex at the bell.
- Broker and fund‑flow rotation: Watch for continued switching into ANZ/WBC/NAB if valuation remains the dominant narrative. Recent coverage emphasised valuation‑driven rotation after CBA’s update.
- Rates path and minutes preview: With the RBA minutes due Tuesday, any desk notes into the open that flag a tougher tone on inflation could influence bank multiple assumptions and deposit competition expectations.
- Capital comfort vs. earnings pressure: CBA’s strong capital and liquidity (CET1 11.8%, LCR 133%, NSFR 116%) and pro‑forma APS 117 boost provide a buffer; the debate is whether margin compression and cost growth (wages/tech) temper FY26 earnings momentum.
The bottom line
CBA enters Monday’s session with robust balance‑sheet credentials and clear growth in deposits and mortgages, but margins and costs remain the swing factors for near‑term share performance. After last week’s drop, the premium valuation is still the lightning rod: any further hints of NIM pressure—or a hawkish‑sounding RBA minutes on Tuesday—could extend rotation into cheaper banking peers, while evidence of stabilising margins would help the shares base.
