LI Ka-shing gave the management of beleaguered Hanny Magnetics reason to smile last night, suggesting that the loss-maker still had potential. That smile may have become strained when Mr Li, speaking at the Hong Kong stock exchange anniversary celebrations, later said he held no Hanny shares. Hanny has sent out circulars to its shareholders warning of even more losses since July 31 this year. '[Hanny] has continued to incur additional losses subsequent to July 31, 1995,' the company said in a circular on its rights issue and new share issue. The company lost $100 million in the four months to July 31. Chairman Wong Sun has cited the backing of Mr Li's Cheung Kong and Hutchison Whampoa as the reason new investors are putting money into the company. European Union anti-dumping charges on 3.5-inch floppy disks imported from third countries could only make matters worse for the company, analysts said. Hanny makes floppy disks in China and Macau, both affected by the EU charges.
