In this paper, we consider a variance-optimal hedge for target volatility options, under exponential Lévy dynamics. Since the payoff of target volatility options is related with realized volatility of some underlying asset, which is path-dependent, it is difficult to price this instrument. Here we will derive an explicit Föllmer-Schweizer decomposition of the contingent claim of target volatility options and then give the explicit expressions of hedging strategies in both discrete time and continuous time.
Keywords: Galtchouk-Kunita-Watanabe decomposition., target volatility options, Föllmer-Schweizer decomposition, Lévy processes, Variance-optimal hedging.
