I agree with @Dui. Certainly the whole sector has suffered in recent weeks/months and actually most of 2018, the so-called boom year for MC stocks as some pundits (or should I say punters) were speculating late last year. It appears most of those stocks mentioned (ZLD, AC8, THC, CAN, MXC) are plumbing previous technical lows established prior to the bullish spike seen last October/November 2017. This is possibly a technical shakeout testing those earlier lows/support levels...
