I know these HUGE drop-offs with MVNT are just one-off events. But after being here for many months now, I also know that this has happened more than once.
I still think this is "residual" selling by those needing cash for other purposes (perhaps to play "runners" as you suggest) who are sitting on HUGE gains for MVNT for shares purchased when it was under a penny or even as far back as when it was trading under $.002 (still almost 1000% gains).
