  • Publication number: 20200279327
    Abstract: A computer-implemented method and a computer system for a risk reversal index comprises a computer processor that is configured to sell at least one out-of-the-money put option on an underlying index, calculate a premium from the sale of the out-of-the- money put option, use the premium to buy at least one out-of-the-money call option on the underlying index, and invest any remaining premium after purchase of the out-of-the-money call option in a cash-equivalent position having a value. The out-of-the-money put option is sold and the out-of-the-money call option is bought on a roll date.
