While trading at six-month lows, the Salisbury-based firm bounced back slightly over the past week after more than $100 million was wiped off its valuation in the week prior.

A nearly 10 per cent share price rise translated into more than $10 million returning to the company’s market capitalisation over the last week, with shares rising from $3.37 to $3.50.

That gave the pharmaceutical company the top spot on the Winners list, with phosphate miner Centrex hot on its heels with an 8.22 per cent increase in the week ending 8 September.

Centrex’s rise followed the news that it had put an agreement with the traditional land owners of an island in the Pacific ‘on hold’ following outrage from members of the Banaban community.

The remaining Winners were Micro-X with a 4.55 per cent share price increase, Adbri up 4.22 per cent, and Beach Energy up 1.57 per cent.

Of the Losers, AML3D saw the biggest losses – down 13 per cent – representing a $4 million valuation fall.

Archer Materials, Aerometrex, Maggie Beer and BHP Group also dropped this week, landing them in the top five Losers in the latest trading week.
