Tesla's worst day in a year hands short sellers a $4.3bn payday

Elon Musk's electric vehicle giant just handed short sellers their biggest one-day windfall in months. Tesla shares cratered 14.5% on Thursday after a second-quarter earnings miss reignited doubts about the company's costly AI and robotics ambitions, a stock many South African retail investors hold through EasyEquities and offshore ETF exposure.
