A poor day's trade for CSL shares has been compounded by a large sale by one of its biggest shareholders.
It is understood one selling shareholder was behind two lines of shares, together worth $266 million, that crossed in early Tuesday afternoon trade.
The lines included one giant parcel of 1.43 million shares, worth $250 million, and a smaller line of 93,000 shares.
Both lines traded at $175.50 a share via UBS's institutional equities desk, led by George Kanaan, investor sources said.
