No, but if a stock has 10% volatility it can move much further than that.Have you ever traded a stock using margin and the price swung 10% against you? if so, did you get a margin call from your broker?
I've been screwed many times using margin even when the stock swung 10% or less against me the loss was too much to handle and I ended up chasing losses and blew my account. It's more about the mental aspect.
