Abstract:
In this paper, we develop asymptotic Asian option hedging methods for the
Black–Scholes markets with transaction costs. We first construct
classical replication strategies and then, using the Leland approach, propose
corresponding modifications for the financial markets with proportional
transaction costs. Sufficient conditions are found on the transaction costs
implying the asymptotic hedging for the constructed strategies. The pricing
problem is also considered. Three cases are studied: the case where the
option price is the same as for the hedging problem without transaction
costs, the case of increasing volatility, and the case where the option price
equals the option price of the “buy and hold” strategy for European call
options.
