These 5 ASX All Ords shares tumbled the most in FY25
1. IDP Education Ltd (ASX: IEL)
The IDP Education share price tumbled 76% to close at $3.67 on 30 June.
IDP Education arranges international student placements in Australia and conducts language tests for students.
In May, IDP Education informed investors that it expects a 28% to 30% fall in student placements in FY25.
On top of that, the company also anticipates an 18% to 20% fall in language tests for the financial year.
Arthur Garipoli of Seneca Financial Solutions says government policy uncertainty about international students has hurt the stock.
This is reflected in the substantial fall in value for the ASX All Ords consumer discretionary share in FY25.
He said: "While the share price has fallen to reflect the downgrade, we see better opportunities elsewhere."
