英文摘要:
The growth of the exhange-traded fund (ETF) industry has given rise to the trading of options written on ETFs and their leveraged counterparts {(LETFs)}. We study the relationship between the ETF and LETF implied volatility surfaces when the underlying ETF is modeled by a general class of local-stochastic volatility models. A closed-form approximation for prices is derived for European-style options whose payoff depends on the terminal value of the ETF and/or LETF. Rigorous error bounds for this pricing approximation are established. A closed-form approximation for implied volatilities is also derived. We also discuss a scaling procedure for comparing implied volatilities across leverage ratios. The implied volatility expansions and scalings are tested in three well-known settings: CEV, Heston and SABR.

中文摘要:
埃芬奇交易基金(ETF)行业的增长导致了ETF及其杠杆交易对手{(LETFs)}的期权交易。我们研究了当标的ETF由一类一般的局部随机波动率模型建模时,ETF和LETF隐含波动率曲面之间的关系。对于收益取决于ETF和/或LETF终值的欧式期权,导出了价格的封闭形式近似值。建立了这种定价近似的严格误差界。还导出了隐含挥发率的闭合形式近似。我们还讨论了一个比较杠杆比率隐含波动率的标度程序。隐含波动率扩展和标度在三个著名的环境中进行了测试:CEV、Heston和SABR。
