Deciding which ASX shares are buys and which ones are sells can be difficult.
To help you figure things out, let's look at three ASX shares that experts are tipping as sells this week, courtesy of The Bull.
Here's what they are saying:

Commonwealth Bank of Australia (ASX: CBA)
The team at Red Leaf Securities thinks that Australia's largest bank is an ASX share to sell now.
While it acknowledges the quality of CBA, it has concerns over its premium valuation at a time when credit growth could slow and borrower stress could increase. It explains:
CBA is Australia's highest quality major bank, but, in my view, quality doesn't always represent value. Its premium valuation leaves limited room for disappointment as rising interest rates potentially slow credit growth and increase borrower stress. Investors could use the opportunity to take profits and consider better-value alternatives elsewhere in the banking sector.
Corporate Travel Management Ltd (ASX: CTD)
Red Leaf Securities is also bearish on this corporate travel specialist and thinks it could be an ASX share to sell.
It has concerns over historical customer remediation and feels the near term risk-reward equation is unattractive. Red Leaf said:
CTD reported improved underlying earnings in fiscal year 2026. However, in my view, questions remain around historical customer remediation, governance, financial controls and funding requirements. In a company update on April 22, 2026, a review had found that UK customers were charged in excess of their contractual entitlement. On September 1, 2026, the company noted about 78 per cent of customer refunds had been agreed or were nearing finalisation. In my view, the near term risk-reward equation remains unattractive.
Xero Ltd (ASX: XRO)
Fairmont Equities has named Xero as an ASX share to sell this week.
It suspects that increasing bond yields and interest rates could be a headwind for technology stocks in the near term. Fairmont explains:
Xero is an accounting software provider. In my view, potentially increasing bond yields and interest rates will continue to be a headwind for technology stocks, such as XRO. Fiscal year 2026 operating revenue increased 31 per cent on the prior corresponding period. However, net profit after tax fell 27 per cent. The gross margin declined from 89 per cent to 83.9 per cent. From a charting perspective, selling pressure follows share price rallies, so the downtrend may not yet be over at this point.
