By arbitraging and market making these differences Da Vinci helps markets to become more efficient providing benefits to end investors. The instruments traded include, but are not limited to:

  • options and futures on single stock equities

  • options and futures on volatility indices and dividends

Da Vinci trades solely with its own money creating natural risk awareness and does not have any customers.

Our Company

Over the past couple of years Da Vinci has been growing successfully and will continue to do so.
