The short term price usually fluctuates and is definitely more volatile in a low float stock like JNSH. Doesn't mean the company isn't solid. This is just the way the market usually interacts when big changes occur.
1st: there's a surge in volume 2nd: those who have yet to do DD place safe bids to get in while they catch up on the DD 3rd: you'll always have sellers before you have buyers, on a larger float stock you won't see that fluctuation much but on a low float like JNSH it's easier to see 4th: people's DD catch up and they start to realize the opportunity and the bids start stacking at the lows (hence the 888K we saw on 10's the other day)
