MJMJ -28% now. Looks like it followed the same pattern as many past high fliers.
One bid up day and a run into the close and closing near the high. (Yesterday)
Following day (today) a pullback at the opening with profit taking and then those that come in and try and catch the pullback and it rebounds as it did nicely off the AM low.
After that it can go either way. Some continue up nicely the 2nd day and others fall hard. Looks like MJMJ might follow the fall hard route here.
