The 26-year-old describes it as "a somewhat silly promise" inspired by the sacrifices her non-English-speaking parents made to raise the family. But she is trying to make that dream come true by investing her savings in the stock market. "Times are so different and investing has become a necessity," says Huynh, who works in sales for a tech firm. With more than a third of her investments in tech stocks, by the middle of July that part of her savings had jumped this year by 50% - a rise of A$31,000 (£16,100; $21,666). The rise in tech stocks, led by firms riding the artificial intelligence (AI) boom, has attracted large numbers of ordinary investors, many of them in their 20s and early 30s, even as some analysts warn that the fervour around AI may be overblown.
