Features of FLEX Options
FLEX Options provide investors with:

  • The ability to customize key contract terms, like exercise prices, exercise styles and expiration dates. Index FLEX options are cash-settled and may have expiration dates up to 15 years from the trade date, approximately 5 to 10 years more than what’s available for most popular indexes.
    • A recent Options Clearing Corporation (OCC) report showed S&P 500 (SPX) options with expirations through 2029, Russell 2000 (RUT) options with expirations through 2025, and Dow 30 (DJX) options with expirations though 2024.
  • Virtual elimination of counter-party risk – guaranteed by the OCC
  • Price discovery in competitive, transparent, auction markets
  • A secondary market, which provides an opportunity to offset or alter positions before expiration
  • Independent daily valuation of prices by OCC
  • Daily price and open interest reports
  • Operational efficiencies of exchange-listed options

The indexes in the Cboe S&P 500 Buffer Protect Index Series measure the performance of a portfolio of hypothetical exchange-traded FLEX options on the S&P 500 Index, and are designed to provide target outcome returns to the US domestic stock market.
