Do we understand delta hedging?


  • Daniel Badagnani

    (Universidad Nacional de La Plata)


We show that the delta-hedged portfolio is not actually risk-free even for brownian underlying due to history dependence in the ammount of hold portfolio. We find this ammount explicitly, as a function of underlying price evolution and option price. This shows that even in the B-S world (perfect market and brownian asset price evolution) the B-S equation can only be an approximation.
