• RISK ARRAYS
  
  Refer to how a specific derivative instrument will change in value, from the present to a specific point in time for a given set of market conditions. For SPAN® purposes, this time period is typically one day. Here, risk array values are calculated basis a single long position. Note that SPAN® views LONG as the purchase of a call or a put and not as market direction strategy. This contrasts to LONG usually referring to the side of the market and not the ownership of an instrument.
