        How Does the SPAN Methodology Calculate Risk for Complex Options Strategies?
        
         
        
        
          
        
        
      
        
     
        
        SPAN calculates portfolio risk by simulating 16 market scenarios to find the maximum one-day loss, crediting offsets from complex strategies.
        
        What Are the Primary Differences between Portfolio Margining and SPAN for a Derivatives Portfolio?
        
         
        
        
          
        
        
      
        
     
        
        Portfolio Margining holistically simulates total portfolio risk for capital efficiency; SPAN uses standardized scenarios to assess component risks.
        
        How Does Span’S Use of Risk Arrays Differ from Tims’s Scenario Grid?
        
         
        
        
          
        
        
      
        
     
        
        SPAN uses pre-calculated, contract-level risk arrays for margin, while TIMS re-prices entire portfolios across a dynamic grid of scenarios.
        
        To What Extent Do Modern VaR-Based Methodologies Supersede the Approaches of Both Span and Tims?
        
         
        
        
          
        
        
      
        
     
        
        Modern VaR models supersede legacy systems by replacing static scenarios with holistic, data-driven simulations for superior risk accuracy.
