PAYD back in early 2000's jumped from teens to .80. About 8 fold for a smaller float is pretty good. One example I was personally in. The first few days I was not able to trade because I did not have in my account from Ameritrade yet. At that time I think it was Datek? Can't recall. Took 2 business days but stock increased during that time because mm's had to cover their naked shares.
