This seminar will examine the returns to positions on FX options based on their implied volatilities and discuss an explanation for the apparent mispricing of these securities.

Seminar abstract

We study the cross-section of returns on FX options sorting currencies based on implied volatilities (IV).

Long straddle positions in currencies with low (high) implied volatilities perform well (poorly). A long low IV-short high IV strategy produces large average returns after transaction costs. total volatility matters rather than any component or transformation of volatility.

The returns are distinct from those in the literature on foreign exchange returns or equity option returns and cannot be explained convincingly by standard risk factors. 

We argue that mispricing is caused by cross-section differences in hedging demand combined with limits to arbitrage.
