Please elaborate.Well, think about the notion of a simple delta hedge: this tells you, to the extent that your model is accurate, what you have to eliminate any risk that cannot be reduced by increasing the frequency with which you rebalance. That has value, doesn't it? Without that, you might just flail away at controlling risk in your portfolio without realizing that you just haven't set things up correctly.
