Investors are still getting to grips with a historic week in global markets in which a struggling and relatively obscure US video game retailer somehow became the world’s most heavily traded stock.

That came after a group of mostly Millennial and Gen Z DIY traders actually pulled off their far-fetched plan – plotted for months in a Reddit forum – to deliberately push the GameStop share price sky-high by buying stock en masse and cause problems for some big dog Wall Street hedge funds in the process in what is known as a “short squeeze” attack.
