Didn't we all kind of expect something like this? - some profit-taking by those who participated in the recent stock issue... The underwriters also had the right to purchase additional stock to play with within 30 days, so some short-term gaming of the pps is hardly surprising.
Oh Flo you're ending the year just like you started:
Tax-loss selling: Save the date
The key thing for investors to remember is that it has a deadline. For both Canada and the US, the last day for tax-loss selling in 2019 is December 31; however, investors should remember that the trade date must be no later than December 27, for processing time. ie the Settlement date.
