That is a obvious thing to happen. BCC or any other coin you take of it is not on an exchanger then there wont be any movement in its price. Just take an example of bitcoin analysis from last week. When everyone knew we can not transact the bitcoin or it is not advisable to transact bitcoin in the period of august then the price of bitcoin was completely frozen and there seem no movement in its volatile nature.
This you can take as an example to know what can happen with BCC. Anyway now some of the exchanges has started and you can convert the bcc right away. This will crash the price of bcc now and will probably increase bitcoin price on positive side.
