While it was not the worst performer among the Magnificent Seven stocks – that bouquet belongs to Apple, which dropped more than 9 per cent – Nvidia attracted a lot of Aussie money on the way up. James Packer is among the most high-profile backers. One of his private investment vehicles, Consolidated Press International Holdings, holds more than one million shares after buying up the stock last year. Packer will have lost more than $US50 million ($80 million) since January alone, but it does not mean he has made a loss on his investment to date. His bet on big tech is a fraction of the exposure of Australians to the market rout, with VanEck estimating that local super funds and fund managers owned as much as $28 billion worth of Nvidia stock in January.
