Implied volatility data & analytics. Our story

When we decided to become a volatility data vendor, we listed the reasons why: volatility data was hardly available from an independent source, and if it was, data quality was – shall we say – substandard. Not much has changed, still today.

We then put our combined expertise in derivatives theory and data management to work. And vowed to create the best implied volatility database money could buy. After all these years, we can proudly state that SIGMA28 is now considered the institutional benchmark for volatility data and analytics. For banks, fund administrators, hedge funds and trading companies. Our volatility data is used for pre- and post trade workflows like risk management, trading, independent valuation and model calibration.

So – how can we be of service?
