Can the exuberance over ASX 200 bank shares last?
There are some mixed views on this. UBS reckons ASX 200 bank shares 'don't appear overly expensive' compared to global peers, whereas Goldman Sachs views them as the most expensive in the world.
Goldman Sachs said ASX 200 bank shares valuations are "skewed to the downside" from here. The broker says there is an expanding valuations discrepancy despite weaker relative profitability.
Philip King, CIO at Regal Funds Management, says Aussie banks are being "attacked from all angles" by competitors such as buy now, pay later operators, non-bank lenders, and private credit.
Martin Conlon from Schroders says the banks' profits will be "flat at best" unless they can reduce costs.
What's ahead for the NAB share price in FY25?
While UBS expects NAB to grow its profits in FY24 and FY25, the broker has a sell rating on the shares. The NAB share price is now trading well beyond the broker's 12-month price target of $30.
Goldman Sachs has a neutral rating on NAB with a 12-month share price target of $34.04.
Earlier this month, NAB paid an interim dividend of 84 cents per share to shareholders.
