摘要
The present invention provides methods and systems for managing short-term risk to a portfolio of securities holdings while executing an outstanding trade list. The methods and systems may include steps of determining covariances between securities in the outstanding trade list and securities in the portfolio of holdings; receiving a risk variable, at least one constraint on the execution of a trade, and a proposed quantity representing a portion of said outstanding trade list desired to be executed at a particular time; and determining an immediately executable trade list based at least in part on the covariances and risk variable. The executable trade list must satisfy all of the trade constraints and also must be substantially equal to or less then the proposed quantity.
