Implied Volatilities and Greeks

Real-time analytics outputs of the highest quality and integrity.

Cboe Hanweck produces real-time implied volatilities and Greeks — Delta, Gamma, Theta, Vega & Rho — on the global listed options markets. Hanweck Options Analytics is powered by the proprietary Volera® engine, a high-performance, hardware-accelerated system capable of performing millions of option valuations per second. Volera’s proprietary calculation process ensures that the latest available prices are used for each computation, while Volera’s supercomputing hardware can tackle the most demanding of market conditions. Volera scales easily to meet ever-increasing message rates.

This cutting-edge technology is already available throughout the entire suite of Cboe Data and Access Solutions.

Volatility Surfaces

In addition to analytics on individual contracts, Cboe Hanweck Options Analytics computes standard volatility surfaces for computing theoretical option prices and more general purpose volatility modeling. Expressed as standard constant maturity tenors with several different money-ness factors, risk managers can be certain to have a continuous set of volatility data points. Our constant maturity approach interpolates volatility points that fall between stated option expiries.

  • Volatility points are calculated on both delta-relative and price-relative (e.g., % of spot) perspectives.
  • Delta- and price-relative points are also available at listed option expiries.
  • Stochastic volatility models such as SABR are also available.

Customizable Instances

If you need a customized volatility model or prefer to tailor data and model inputs, Cboe Hanweck can configure a unique, dedicated instance for your business needs.
