Parity Relations and Delta Hedging

Show Summary Details

Preview

The structure of the hedging portfolio is quite complicated, and is continuously rebalanced. This continuous rebalancing presents a problem since real life trading has a cost. For managerial purposes, it would be better to replicate a claim with a portfolio that remains constant over time — the buy-and-hold portfolio. This chapter analyses the buy-and-hold portfolio, sensitivity measures known as “the greeks”, and delta and gamma hedging. Practice exercises are included.

Keywords: hedging; pricing; Black-Scholes model; buy-and-hold portfolio
