Our approach is more efficient than the tree methods because recalculating the option prices is much quicker. Applying put¡Vcall duality to an HSHP yields a tradable semistatic hedging portfolio (SSHP). Numerical results indicate that an SSHP has better hedging performance than a delta-hedged portfolio. Finally, we investigate the model risk for SSHP under a stochastic volatility assumption and find that the model risk is related to the correlation between asset price and volatility. ? 2018 Wiley Periodicals, Inc.American floating strike lookback optiondynamic hedgingmodel riskput¡Vcall dualitysemistatic hedgingstochastic volatility model[SDGs]SDG8journal article10.1002/fut.219862-s2.0-85058076275https://www.scopus.com/inward/record.uri?eid=2-s2.0-85058076275&doi=10.1002%2ffut.21986&partnerID=40&md5=ad76b4180ac60d6b2a451774612e88b6
