With CBA shares trading at such astronomical highs, perhaps you might be thinking it's time to sell.
John Athanasiou, CEO of Red Leaf Securities, says you shouldn't. Here's why.
Expert says hold your CBA shares
The investment manager says CBA remains a market leader with strong profitability and dividend stability.
Athanasiou says (courtesy The Bull):
The company posted an unaudited cash net profit after tax of $2.6 billion in the third quarter of fiscal year 2025, up 6 per cent on the prior corresponding period.
Operating income was up 1 per cent driven by lending volume growth and higher trading income.
Looking ahead, Athanasiou sees several factors that may dampen share price growth.
… potential superannuation tax changes, elevated valuations and slowing credit growth temper near-term upside.
Investors may consider holding until more clarity on Federal Government policy emerges, or until the macroeconomic outlook improves for banks.
The Federal Government has proposed lifting the tax rate on superannuation earnings, including unrealised capital gains, above $3 million.
