Standard Portfolio Analysis of Risk [SPAN] Law and Legal Definition
Standard Portfolio Analysis of Risk (SPAN) is a comprehensive system which is designed to accurately evaluate the risk in an entire portfolio and to match performance bond [margin] to portfolio risk more accurately than previously used methods. SPAN treats futures and options uniformly, while recognizing the unique risk characteristics of options. [Baghdady v. Robbins Futures, Inc., 1999 U.S. Dist. LEXIS 3394 (N.D. Ill. Mar. 11, 1999)].
