There's been a pattern of runs occurring about a week before earnings dates on the heavily-shorted securities, so with the AMC E.R. coming on March 1st, a bump across that sector in the middle part of this upcoming week sounds about right in that regard. Not to mention the Batman movie coming out next week as well to provide an additional "catalyst" narrative.
And once AMC blows, so should GME, and that could very well unleash several others as a domino effect.
