Almost certainly is TRP who allegedly have lost a cool 0.5...

It has been widely reported that T Rowe Price may have lost $500 million in its investment in 2 failed US banks (Google it) In that case the single trade today of 51.7 million shares could well be the overhang that has now cleared hopefully. It means that somebody has picked up a near 5% stake in the Company and it was just a matter of time before the two parties agreed a price. Hopefully the ASX will force the buyer to declare this in the next few days.

Almost certainly is TRP who allegedly have lost a cool 0.5 BILLION on investment on their investment in 2 failed US banks.
