I think a few profit takers... there are always people who will grab a 200% gain - some NEED to do that to pay bills - some people grabbed a 150-200% gain on SOME shares as they sell in increments as it goes up in price. Many people cannot resist taking a profit (they see the trees before the forest).
Sometimes they are right and they are the winners - but this time it looks like HOLDING for the PRs and maybe beyond for some or many is the best bet. With DISNEY involved - I think we are safe waiting for the PRs because this is NOT a typical penny stock where often there is no proof of a real business. We have Stan Lee and Disney --> safe to hold for the BIG PLAY when the PRs come out.
Look at man big runs in stocks and there are always big dips (bear raids, MM games, shorts covering, flippers, profit takers, or lulls in the trading). I cannot say to hold forever but I think it is a good idea to hold until Disney releases the PRs - even if there are dips during the day.
Just my opinion
