Canopy Growth Corporation $CGC has been on a bull run since 2016, when it bottomed at around $1.00 a share. It peaked in 2018 at an all-time-high around $59 a share. I am almost sure a major pullback is coming.CGC Daily Chart(click to enlarge)Another 50% Correction?- From that high of $59, price has already retreated to $31.40. This was almost a 50% decline.- In fact, it was more than that when price hit a low of $28.10 last week.- But I think there will be further downside towards $15, about another 50%.- Just look at all that volume that came in when price moved from $20 to almost $60. - I think this is highly speculative volume, much like crypto in late 2017. - There is possible support around $20, but I think general market risk will drag CGC even further.- $17.00 is a support/resistance pivot that might also provide some buying. The 2018-low is around here.- But I personally would not look for an entry until price gets in the $11-$15 area. - This is the resistance area for the 2017 consolidation, and I believe it will act as support. - Also, at $15, price will likely meet a rising trendline, which might also provide some support.
