News: PTM Platinum Asset Management Posts FY Net Profit Attributable Of $157.7 Million, page-408

You are right.
Platinum benefited from the good performance of Asia ex Japan in June, which seems to be + 0.5 % according to VAE.
Unfortunately, it was also partly offset by their exposure to Japan. Nikkei 225 was - 3.2 % in June and - 5.4 % in AUD, according to my calculation.

At the end of May, their main fund (Platinum International Fund) had a net exposure of 12.8 % for Asia ex Japan and 8.3 % for Japan.

So, they had a lot of good bets in June :
- their short exposure to tech,
- their exposure to USD,
- and their exposure to Asia ex Japan (as you mentioned it).

At 29/6/22, Platinum International fund NAV performance was - 2.2 % MTD.
