Back-adjusted data: This is a data series created by calculating a backward cumulative adjustment for the difference between the current Contract and previous Contract on the day specified in the Rollover Period. For example, if on the rollover day (ie expiration), the current Contract is 94.80 and the previous Contract is 95.00, then the Back-Adjusted Contract is the previous Contract - .20 + plus any cummulative adjustment prior to the rollover date (if any). The Back-Adjusted data series is especially useful when analyzing long-term studies.
Note: Since the adjustment for the Back-Adjusted contract is cumulative, it is possible to produce negative (-) price values.
