Abstract: A system and method for near-instantaneous portfolio protection is provided. The portfolio protection tool is configured to be activated/deactivated nearly instantaneously with minimal customer inputs and efficiently provides customizable risk-management solutions for individual investors and advisors alike. The system includes a Market Data Server that receives market data from electronic intra-day financial market data sources, processes and selectively compiles salient market data points. A Risk Pricer Server computes, based on user-defined protection period and protection level settings, a risk level and a price for the protection on the user's portfolio. A Book Manager identifies specific trades required to provide the portfolio protection as a function of an aggregate risk to multiple customers. A Trader is configured to execute the specific trades.
