Commonwealth Bank of Australia (ASX: CBA)
Shaw and Partners has named this big four bank as an ASX share to sell this week.
It highlights that CBA shares continue to trade at a significant premium to peers despite its subdued earnings growth outlook. It said:
In our view, the stock trades at a significant premium to domestic peers and on historical valuations. While the bank maintains a high quality franchise and strong market position, earnings growth is expected to remain modest amid competitive lending conditions and regulatory pressures.
Recent Federal Government initiatives aimed at increasing housing supply and improving affordability is likely to lead to intensifying competition across the mortgage market and place pressure on lending margins. Current valuations leave limited scope for further earnings driven upside. Investors may wish to take profits and re-deploy capital into opportunities offering stronger risk-adjusted return potential.
Fortescue Ltd (ASX: FMG)
The team at RaaS Group has named iron ore giant Fortescue as an ASX share to sell.
It thinks the outlook for iron ore is less appealing than other commodities. It said:
The iron ore producer generated revenue of $US16.966 billion in full year 2026, up 9 per cent on the prior corresponding period. Statutory net profit after tax of $US2.860 billion was down 15 per cent, which included a $US525 million non-cash impairment charge relating to the Iron Bridge project and a $US73 million compensation claim expense. The final, fully franked dividend of 46 cents a share was down from 60 cents a year ago.
Capital expenditure and investment guidance in full year 2027 is forecast to increase on full year 2026. The outlook for the iron ore price isn't as appealing as other commodities. The share price has fallen from $22.99 on May 14 to trade at $17.22 on September 10.
Woolworths Group Ltd (ASX: WOW)
Shaw and Partners has also named supermarket giant Woolworths as an ASX share to sell.
While it acknowledges that Woolworths is a quality business, it thinks investors should be taking profit after a recent rally and focusing on investments with a more attractive risk-reward profile. Shaw and Partners said:
The supermarket group has experienced a strong recovery in the past year, with the share price recently trading near the upper end of its historical range. While the company remains high quality with a leading position in Australian food retailing, much of the recent improvement appears to be reflected in the WOW share price. Earnings growth is expected to remain relatively steady rather than exceptional, limiting scope for further share price appreciation from current levels.
Following the recent rally, investors may consider taking profits before re-allocating capital to opportunities with stronger growth potential and a more attractive risk-reward profile.
