The Financial Markets Authority has been ordered to provide more details of its market manipulation case against Mark Warminger.
Warminger, who is on extended leave from his position as a portfolio manager at Milford Asset Management, is fighting a FMA lawsuit due to go to trial in September.
The FMA alleges Warminger misused his privileged position with an institutional investor to trade shares not for a genuine commercial purpose but to increase their market price so that he could then transact significant off-market sales at a greater profit.
Its claim against him, for example, alleges certain trades of Fisher & Paykel Healthcare shares were likely to have created a false or misleading appearance of the extent of active trading and the supply, demand, price, and value of that stock.
However, Warminger went to the High Court at Auckland last month to ask for more details of the FMA's claim.
