#1 ETFs track action, they don't cause it...so no #2 Aphria likely headed lower not higher...so no #3 Cronos deal met with tepid response reflecting a negative post-legal sentiment...so no #4 Broader markets very weak and will likely continue downtrend with political turmoil in DC among many other national/global problems...so yes
I'll say MJ & HMMJ wind up ~5% lower by end of week. Maybe near bottom but not there yet and may be a while. Disappointing recent earnings and looming fraud scandals continue to weigh down any rebound.
If forced to pick a potential catalyst to make above assessment null & void here ya go, matey...
