Shares of Canopy Growth Corp (CGC), the largest medical marijuana company in Canada, have been halted from trading multiple times in the last week by the Toronto Stock Exchange due to excessive levels of volatility. That intervention spooked a lot of investors – triggering a wave of profit taking after Canopy delivered big gains in the last few months. I view the correction as healthy. The sector was overbought. The pullback creates an opportunity for new investors to buy when shares are trading well off the 52-week high.
