The Financial Post reports in its Wednesday edition that Canada's national investment industry regulator says it has seen a 270-per-cent spike in complaints and other calls about do-it-yourself investing services, a surge that comes as retail investors have flocked to the platforms during COVID-19 lockdowns. The Post's Barbara Shecter writes that extreme price swings in some stocks, such as Gamestop, Blackberry and AMC has led to the surge in complaints. Citing the recent market volatility, which appears to have been driven in part by retail investors on DIY platforms such as the U.S. app Robinhood, the Investment Industry Regulatory Organization of Canada urged investors conducting their own trades to arm themselves with reliable information and enough knowledge about investment products to protect themselves from market volatility. "We urge investors to be careful about where they are getting their investing information, as many sources are unregulated and may contain inaccurate information," said Lucy Becker at IIROC. "This may lead to misinterpreting investment research and subsequently betting the farm." Last month, some of the country's biggest banks struggled with outages and delays in processing trades.
