I know that the trade was an outlier, first thing and that you're likely right...probably a newbie type investor using a market order right at the opening bell.  

But now its part of the narrative, anyone going to check RVXCF is going to see that the 52 week high is $3.59....there won't be an asterisk saying 52 week range $0.84 - $3.59*  with a footnote explaining that the $3.59 high was the result of a trade on April 23rd  that was outside the trading range that day.

Thinking about it....its a nice target, $4.80 or so CDN.  I'm now wishing it was higher :-)
